Book summary “Maintenance and reliability best practices”: summary

Introduction

You face intense global competitive pressures and widespread skill shortages that threaten your plant operations. Equipment failures and reactive firefighting drain your resources and limit your production capacity.

Achieving plant excellence requires shifting from reactive maintenance to proactive reliability through structured work management, condition monitoring, and total workforce engagement.

Ramesh Gulati shows you how to maximize asset availability using proven best practices. The book guides you through foundational benchmarks, workforce management, problem-solving methodologies, and advanced maintenance strategies.

You will discover answers to critical operational challenges:

• What defines an industry benchmark and how do you overcome adoption barriers?
• How do you manage human capital and build a reliability culture?
• What tools eliminate root causes instead of treating symptoms?

1. Introducing Best Practices and Benchmarks

A best practice is a documented technique, method, or process that consistently delivers superior results and performance compared to any other approach. Rooted in Frederick Taylor's management principles of finding the one best way, a best practice serves as an industry benchmark of excellence. When implemented properly, it improves efficiency, reduces complications, and enhances overall operational performance.

Dick Fosbury revolutionized high jumping in the 1968 Summer Olympics by going over the bar back-first, defying the standard practice of jumping head-first and winning the gold medal.

A best practice delivers superior performance and serves as an industry benchmark, but adoption is often blocked by institutional barriers and poor understanding of asset failure factors.

What Is a Best Practice

The adoption of best practices is frequently hindered by specific institutional barriers and common psychological excuses within organizations. According to the American Productivity and Quality Center, the three primary barriers are:

• a lack of knowledge about current best practices;
• a lack of motivation to change;
• a lack of required skills.

Top excuses include thinking current processes are fine, past failures, and perceiving the organization as uniquely different. Organizations ultimately fail to implement best practices due to four foundational missteps rather than mere operational oversight. These include a failure to understand business operational risks, an inability to correlate best practice cause and effect, a general fear of change, and persistent budget and schedule constraints.

Asset Performance Factors

An asset's actual operational performance is governed entirely by three distinct factors: its inherent reliability, its operating environment, and its maintenance plan. Inherent reliability is built in during the design and component configuration phase. The operating environment involves operational conditions and operator skills, with studies showing 40 percent or more of failures stem from operational errors. The maintenance plan defines how the asset is serviced to prevent unscheduled downtime.

Performance Benchmarks

Maintenance cost as a percentage of replacement asset value serves as a primary performance measure for evaluating maintenance excellence. Replacement asset value is the current replacement cost of all industrial facility assets, including the cost of removing old assets and installing new ones, sourced from engineering or insurance carriers rather than accounting book values. World-class maintenance organizations maintain exceptionally high percentages of planned work and robust schedule compliance rates.

Schedule compliance measures completed approved scheduled tasks versus available labor hours, while planned work calculates work orders where all parts, specifications, and procedures are defined beforehand. Typical organizations achieve low compliance, whereas world-class performers reach significantly higher thresholds. Organization A has a typical schedule compliance of 40 percent, whereas Organization B has applied best practices and achieved a schedule compliance of 80 percent. Typical organizations achieve 30 percent planned work, while world-class organizations reach 90 percent.

2. Workforce Management and Development

Human capital volatility requires active employee lifecycle steering, structured job analysis, and treating training as a long-term strategic investment.

Managing human capital requires continuous attention across a four-step lifecycle to reduce turnover.

The Walt Disney Company refers to its customers as guests to instill intimacy and culture from day one, instructing employees that their objective is to create happiness.

You must navigate talent through hiring, mentoring, recognition, and retention. Use these practices to steer the employee life cycle:

• hire talent, not just trainable skills;
• make newcomers feel welcome and assign a mentor;
• give positive feedback, rewards, and recognition frequently;
• provide ongoing challenges and development to retain employees until retirement.

Employee Life Cycle

Dr. W. Edwards Deming developed 14 foundational principles focused on people development, leadership, and process improvement. You must eliminate fear and drive out slogans that demand zero defects without improving underlying processes.

Five distinct generations coexist in the modern workplace. The workforce spans the Silent Generation, Baby Boomers, Generation X, Generation Yers, and Generation Zers.

70 percent of participants in a web poll experienced a generational rift. Gen Y and Gen Z will constitute nearly 70 percent of the global workforce within a few years, while Gen Z makes up 25 percent of the U.S. population.

Bridging generational differences requires targeted workplace adaptations:

• team up a seasoned Silent employee with a younger generation worker for mutual knowledge transfer;
• provide Gen Xers with training and development opportunities;
• offer Gen Yers work schedule flexibility and clear purpose;
• respect Gen Zers' digital fluency and desire for independent work environments.

People spend over 75 percent of their time in interpersonal situations to get work done. You must master active listening to prevent misunderstandings and conflict.

Communication and Development

Effective time management allocates limited time to the right activities through planning and delegation.

Job task analysis establishes foundational duties and skill sets for a position. You must gather requirements using structured methods:

• review job classification systems and conduct incumbent interviews;
• observe workers and interview area supervisors;
• use structured questionnaires and task inventories;
• group collected information into duties and tasks, environment, tools and equipment, relationships, and requirements categories.

Training must be treated as a strategic investment rather than an expense. Studies indicate that 70 to 80 percent of equipment failures are self-induced. An increase in workforce education by 10 percent leads to an 8.6 percent increase in productivity. Only 18 percent of U.S. manufacturers spend more than 40 hours per person annually on training, compared to 29 percent in Mexico.

You should build a comprehensive program using specific methods:

• establish a training database to track required hours, certifications, and skill assessments;
• include regulatory safety, technical repair, and organization-specific modules in the training curriculum;
• partner with local community colleges for remedial reading and math courses.

Organizational Structure

Professional certifications measure understanding of a standard body of knowledge. The labor force participation rate in 2018 was 87.7 percent for workers with credentials compared to 57.8 percent without them.

You should guide professional growth with specific credentials:

• identify required competency levels for asset operation and maintenance;
• encourage professionals to pursue recognized credentials like CMRP, CMRT, CRL, or CMM;
• use certification standards to assess employee knowledge gaps and build targeted training programs.

The percentage of workers aged 65 to 84 is projected to increase by 48.3 percent between 2016 and 2030. Succession planning and organizational design mitigate disruptions caused by retirements.

You can maintain workforce continuity through structured steps:

• review management personnel to determine backups for key positions;
• identify critical positions and future competencies;
• develop individual development plans and mentoring programs for high-performing employees;
• evaluate hybrid organizational models combining centralized specialized staff with area-assigned maintenance technicians.

3. Problem Solving and Quality Tools

Systematic problem-solving tools such as root cause analysis, FMEA, and Six Sigma allow you to eliminate process defects rather than merely treating superficial symptoms.

Root Cause Analysis is a structured investigation methodology designed to discover the prime cause of an undesirable condition or failure. Studies indicate that 80 to 90 percent of unwanted situations caused by failures are related to process problems, while 10 to 20 percent of failures relate to personnel or people problems.

A plant manager repeatedly found oil puddles on the floor near a tube assembly machine. Treating it as a personnel issue led to reprimands, whereas an RCA traced the oil leaks through defective replacement seals, poor supplier quality from lowest-bidder purchasing, and finance mandates to cut costs based on the manager's own cost-reduction memo.

You can execute Root Cause Analysis using a six-step process:

• Define the problem—failure.
• Collect data/evidence about issues that contributed to the problem.
• Identify possible causal factors.
• Develop solutions and recommendations.
• Implement the recommendations.
• Track the recommended solutions to ensure effectiveness.

The 5 Whys analysis is a simple, iterative problem-solving technique used to quickly uncover the root cause of a failure by repeatedly asking why an event occurred. You can apply this technique by asking a sequence of targeted questions:

• Why is our customer (operations department XYZ) unhappy?
• Why were we unable to meet the agreed-upon schedule for delivery?
• Why did it take so much longer?
• Why did we underestimate the work?
• Why didn’t we do the proper planning—detailed analysis—for this job?

The Cause-and-Effect or fishbone diagram provides a structured, visual method to categorize potential causes of complex problems and identify root causes during team brainstorming sessions. Invented by Dr. Kaoru Ishikawa, the tool places the problem in the head of the fish and organizes potential causes along major categories.

You can build a fishbone diagram using these steps:

• Define the problem (head of the fish).
• Brainstorm causes of failures.
• Identify/document all causes by major category (bone).
• Select any causes that may be at the root of the problem.
• Develop a corrective action plan to eliminate or reduce the impact of the causes selected in Step 4.

The Pareto principle states that an imbalance exists between causes and results, where approximately 80 percent of effects are created by 20 percent of causes, allowing organizations to focus resources on the vital few issues. Plant asset analysis indicated that three specific assets—Air Compressor #1, Crane 150 Ton, and NC Machine #3—were the major contributors to plant downtime failures. You can use Pareto charts to reduce or eliminate 70 to 80 percent of plant downtime by taking care of top failing assets.

Process Improvement Tools

Failure Mode and Effects Analysis is a systematic, qualitative method used to evaluate potential technical risks, determine how assets can fail, assess consequences, and prioritize mitigation actions using Risk Priority Numbers.

FMEA examines items, functions, failure modes, failure causes, and failure effects. The Risk Priority Number is calculated as the mathematical product of severity, probability, and detection ratings. Severity uses a 1 to 10 scale where 1 represents no effect and 10 indicates very severe. Probability uses a 1 to 10 scale where 1 represents not likely and 10 indicates inevitable.

You can execute an FMEA project through structured implementation steps:

• Establish the objective of the FMEA and identify analysis team members.
• Describe the asset or process and its functions.
• Create a block diagram of the asset or process.
• Create a spreadsheet or a form and list items or components and the functions they provide.
• Identify which component could fail, how it will fail, and why it will fail.
• List failure modes for the functions of each component or process step.
• Identify the causes of each failure mode.
• Identify failure mechanisms that will create a random or wear-out type of failure event.
• List the effects of each of the failure modes.
• Establish a numerical ranking for the severity of the effect.
• Estimate the probability factor for each cause.
• Assess the likelihood that current control measures will detect the cause.
• Calculate and review the risk priority numbers.
• Identify current practices, including PM plans or controls in place.
• Determine the recommended actions to address potential failures with a high RPN.
• Assign responsibility and a target completion date for these actions.
• Track actions taken and reevaluate risk.

Six Sigma is a statistical quality improvement methodology that seeks to reduce process variation and eliminate waste. Achieving Six Sigma means delivering only 3.4 defects per million opportunities. One sigma performance yields 691,462 defects per million opportunities and 30.85 percent good output. For problem solving, Six Sigma utilizes the DMAIC structured five-phase cycle: Define, Measure, Analyze, Improve, and Control.

A Six Sigma project at Plant XYZ targeted hydraulically actuated valve downtime. By auditing valve health across six plant zones, analyzing root causes with fishbone diagrams, restructuring PMs, and cleaning oil systems, downtime hours were reduced by 28 percent in two years and 42 percent in four years, while maintenance costs dropped by 22 percent.

Value Stream Mapping provides a visual graphical map of end-to-end workflow and information flow to identify non-value-added activities. You can construct VSM through eight structured steps:

• Step 1: Identify the problem and set expectations.
• Step 2: Select the team.
• Step 3: Select the process to be mapped.
• Step 4: Collect data and produce the current-state map.
• Step 5: Critique/evaluate the current state.
• Step 6: Map the future state; identify waste and non-value added items.
• Step 7: Create an action plan and implement it.
• Step 8: Measure and evaluate results; readjust the plan if needed.

The Theory of Constraints posits that an organization or system is like a chain limited by its weakest link. Developed by Eliyahu M. Goldratt, TOC dictates that you must manage bottlenecks to maximize overall throughput through a distinct sequence:

• Communicate the goal of the process or organization.
• Identify the constraint that prevents meeting that goal.
• Exploit the constraint by ensuring it is dedicated solely to what it uniquely adds.
• Elevate the constraint by increasing its capacity or reducing setup time.
• Return to Step 1 and repeat if the constraint has moved to another system.

4. Standards and Asset Management Systems

Implementing recognized management standards and standardized asset management systems provides a rigorous framework for continuous operational improvement.

Codes dictate minimum accepted rules of what must be done to ensure safety and quality. Standards provide the step-by-step how-to instructions to execute codes. Specifications outline explicit, additional requirements for a specific product or process that go beyond standard or code minimums. Regulations are mandated by government bodies and enforceable by law.

The ASME Boiler and Pressure Vessel Code serves as a mandatory safety code, while standard pipe dimensions or testing methods dictate how to build, and specific carbon maximums of 0.23% in A106 Gr B pipe define a commercial specification.

Major historical disasters and infrastructure incompatibilities catalyzed the creation of national standards and standardization bodies. The absence of unified standards historically led to major catastrophes, such as fire engines arriving to help cities only to discover their hoses could not connect to local hydrants, or trains being forced to unload because track gauges varied between regions.

Following the disastrous 1904 Baltimore fire which engulfed an 80-block area because visiting fire trucks from New York, Philadelphia, and Washington could not hook up to local hydrants, the nation researched over 600 fire hose couplings to create a uniform national standard.

Codes and Standards

Codes and standards evolved to prevent historical infrastructure failures. Documented events include 7000 BC cylindrical stones used as units of weight in Egypt, 1120 King Henry I establishing the yard based on his forearm, and 1689 Boston passing a brick size law of 9x4x4 inches after a fire. In 1864, a railroad gauge of 4 feet, 8.5 inches was mandated for the Transcontinental Railroad, and the 1904 Baltimore fire destroyed 2,500 buildings over 30 hours.

ISO Management Systems

ISO 9001 provides a process-oriented quality management system based on the Plan-Do-Check-Act cycle to ensure consistent product and service delivery. The standard contains 10 sections total in ISO 9001:2015 and rests on 7 core principles of a Quality Management System. Organizations like the Aerospace Testing Alliance at the Arnold Engineering Development Complex and Jacobs implemented ISO 9001 to all work processes, including asset management, achieving certification back in 2004.

The ISO 55000 series establishes formal requirements and guidance to optimize physical and intangible asset management and maximize organizational value. There are three standards in the series: ISO 55000, ISO 55001, and ISO 55002. The system rests on four fundamentals of asset management: Value, Alignment, Leadership, Assurance.

ISO 31000 provides a structured, adaptable framework for identifying, analyzing, and treating risks to enhance organizational governance and decision-making. The standard features 6 clauses in ISO 31000:2018 and breaks risk assessment down into 3 components: identification, analysis, evaluation.

ISO 14224 establishes a standardized taxonomy and data collection format for equipment reliability and maintenance across industrial lifecycles. It relies on 3 main categories of collected data: equipment data, failure data, maintenance data.

Implementation Steps

Implementing an ISO management standard or asset management system requires a methodical 12-step procedure from initial comprehension to ongoing recertification. You must maintain certification through continuous improvement and mandatory recertification every 3 years.

• 1. Understand the standard and compulsory shall statements.
• 2. Perform a gap analysis with internal or external resources.
• 3. Acquire top management support and establish an asset management policy.
• 4. Identify all regulatory, customer, and cultural requirements.
• 5. Define the scope of the asset management system using a strategic asset management plan.
• 6. Define processes, procedures, and interactions using SIPOC analysis and place them in a central system.
• 7. Implement processes and procedures in a management documentation system or computerized maintenance management system.
• 8. Establish comprehensive employee training and awareness programs focused on change management.
• 9. Choose an external certification body or registrar early in the project.
• 10. Conduct rigorous internal audits to verify process compliance and fix nonconformities.
• 11. Undergo a two-step certification audit involving a document review and an on-site operational records review.
• 12. Maintain certification through continuous improvement and mandatory recertification every 3 years.

5. Leadership and Reliability Culture

Transitioning to a proactive reliability culture requires distinct leadership actions, clear strategic frameworks, and structured change management to overcome resistance.

Managers deal with today's operational details, budgets, and schedules. Leaders are concerned about tomorrow, establishing vision, and providing direction and resources. In 1939, Kurt Lewin and researchers identified leadership styles as authoritarian, participative, and delegative. Authoritarian leaders maintain strict control and independent decision-making. Participative leaders involve team members in critical decisions, fostering motivation. Delegative leaders offer little guidance, which can lead to poorly defined roles. Various researchers have expanded leadership theory into styles such as transformational, situational, transactional, and servant leadership. Oren Harari synthesized Colin Powell's approach into 18 lessons that emphasize responsibility, challenging elites, anticipating problems, and maintaining perpetual optimism as a force multiplier.

• Being responsible sometimes means pissing people off.
• Never neglect details.
• Look for intelligence, judgment, integrity, and a capacity to anticipate.
• Use the formula P = 40 to 70 for probability of success based on information gathered, then go with your gut.

An organization requires a complete strategic framework consisting of vision, mission, values, strategies, and goals to achieve long-term success. While a vision defines the achievable dream and where the organization wants to go, a mission details the purpose and scope of operations, translated into specific actionable goals. More than 6,000 certified professionals hold the CMRP designation worldwide. Highly engaged employees significantly boost productivity, reduce turnover risks, and improve financial returns for their organizations. Companies with high employee engagement enjoy 26 percent higher employee productivity, 13 percent greater total returns to shareholders over five years, and 20 percent fewer days of work missed by highly engaged workers.

Strategic Framework and Culture

Effective cultural change requires a structured change management process to minimize employee resistance and address what is in it for you. Employees must see clear benefits and trust the proposed changes, moving out of their comfort zones through structured models like ADKAR, Kotter's eight-stage process, or Lewin's unfreeze-change-refreeze model.

• Increase understanding of why the change is needed.
• Set clear goals and expectations.
• Establish a process for praise and recognition.
• Define and clarify roles.
• Establish and standardize processes and procedures.

Transitioning from a reactive maintenance culture to a proactive reliability culture takes years of consistent leadership, training, and failure prevention focus. In a true reliability culture, all stakeholders across the asset life cycle collaborate to ensure high uptime, reasonable maintenance costs, and a systematic focus on root cause analysis and defect elimination.

Contrast three plant scenarios handling a failed valve breakdown. Reactive plants fix symptoms under urgency. Proactive plants utilize CMMS data, monitor conditions, and update preventative maintenance tasks.

• Identify all assets with criticality and documented maintenance plans.
• Implement a defect elimination program.
• Apply 80/20 principles to prioritize work.
• Ensure most work is planned and scheduled.
• Perform regular plant reliability analysis to improve uptime.

6. Work Management Planning and Scheduling

Maintenance craft productivity, known as wrench time, typically hovers between 30 to 60 percent. Every hour invested in proactive planning saves one to three hours in actual work execution by ensuring the right tools, parts, and instructions are available upfront.

Proper work planning drastically increases maintenance craft productivity by eliminating wasteful interruptions and wait time.

Planning Basics

Planning focuses on "what and how" by defining job steps, required skills, tools, and materials. Scheduling focuses on "when and who" by coordinating resource availability with production schedules.

Shop AB with 20 craft personnel and zero planners achieves 320 labor hours per week at 40 percent wrench time, whereas Shop XY with 18 craft personnel and two planners achieves 432 labor hours per week at 60 percent wrench time.

Asset criticality is calculated using risk criteria such as safety, environmental impact, operational consequences, and maintenance severity. The resulting Asset Criticality Number helps focus reliability efforts on the most vital assets.

• Evaluate five criteria elements based on the consequences of failure
• Calculate the asset's criticality number by taking an aggregate of all factors divided by the number of factors
• Assess asset criticality using a 1 to 5 scale ranging from ancillary assets to critical safety-related items
• Assess work impact if not corrected using a 1 to 5 scale ranging from efficiency improvements to immediate threats to safety
• Calculate work priority by multiplying Asset Criticality by Work Impact

Scheduling and Backlog Control

A work order with an asset criticality of 5 and a work impact of 4 results in a priority score of 20, which outranks a task with a priority score of 16. An industry benchmark for a healthy maintenance backlog is four to six weeks of available labor hours. This volume prevents technicians from sitting idle while keeping high-priority proactive work flowing steadily.

Effective scheduling relies on structured weekly and daily allocations of available craft hours based on job plans, priorities, and cross-functional agreement.

• Multiply the average labor hours available per week by 4 to determine the lower bound of the backlog
• Multiply the average labor hours available per week by 6 to determine the upper bound of the backlog
• Develop a 1-week schedule for each crew based on available craft hours, highest skill forecast, and job priorities
• Assign work for every available work hour while allowing for emergencies by scheduling easily interrupted tasks
• Develop a daily schedule one day in advance by matching personnel skills and current job progress using crew supervisors

A department with 10 technicians providing 400 total labor hours per week should maintain a backlog between 1,600 and 2,400 hours, averaging around 2,000 labor hours.

• Identify and appoint a turnaround planner 6 to 8 months in advance
• Identify and appoint a turnaround manager 3 to 4 months in advance
• Freeze the turnaround scope at least 4 weeks before the start of the shutdown
• Schedule all work to be completed in 90 percent of the approved duration, leaving 10 percent as contingency
• Ensure all materials, tools, and cranes are delivered at least 1 day before the shutdown starts

7. Materials and Inventory Management

An MRO storeroom must provide the right parts and supplies at the right time and location to minimize downtime. In a poorly run storeroom, technicians spend 20-30% of their time in a shift hunting for parts. This failure severely impairs asset availability. You must balance a reasonable amount of spare parts for emergencies against carrying costs.

Effective MRO storeroom operations rely on ABC inventory stratification, strict cycle counting accuracy, and optimized replenishment calculations.

Storeroom Operations

You must secure the storeroom from the main plant using walls or cages to prevent pilferage. Fast-moving items go in the front, while heavy items stay low near the floor. You keep oil supplies away from the main storage area to meet fire and safety requirements.

• Provide the right spare parts, supplies, and tools.
• Deliver the needed items to the right location at the right time.

Parts kitting consolidates all components required for a scheduled maintenance task into a single container. You pick listed parts and place them into a kit bin for a specific work order. You move the container to a holding area and scan it into the location.

Inventory Control

ABC analysis categorizes inventory based on value and usage rate to separate the vital few from the trivial many. Category A items represent 10-20% of items averaging 15% and consume 60-80% of total cost. Category B items represent 20-35% of items averaging 25% and consume 15-25% of cost. Category C items represent 55-75% of items averaging 65% and consume 5-15% of cost.

You must maintain inventory accuracy of 95% or better to prevent repair delays. Inaccurate records cause hidden stock and deadstock as technicians hoard items.

• Record all parts received against a purchase order in the inventory system.
• Record specific data such as manufacturer number, serial number, lot size, cost, and shelf life.
• Record all parts issued to a work order accurately along with employee name, number, equipment, and projects.
• Return all unused parts after a repair or PM, record them in the system, and put them back into the correct location.

Economic Order Quantity determines the optimal order size that minimizes combined ordering and carrying costs. Typical ordering costs vary from $20 to $200 per order, while annual carrying costs vary from 20 to 30% of item value. Vendor-managed inventory lets suppliers maintain agreed inventory levels at your site. Automated identification technologies like barcodes, QR codes, and RFID streamline data entry.

8. Maintenance Strategies and Condition Monitoring

Reliability and maintenance are fundamentally different concepts where reliability is a design attribute that must be engineered into an asset, whereas maintenance is a tactical task that only sustains existing reliability. You face a situation where 60% to 80% of total life cycle costs consist of operations and maintenance expenses. Because these costs become largely fixed during the early design and development phase, engineering assets for RAMS2O is your most effective cost-reduction strategy.

Optimizing asset reliability requires shifting from calendar-based maintenance to condition-based monitoring and reliability-centered maintenance principles.

Reliability-Centered Maintenance

Reliability-Centered Maintenance shifts your preventive maintenance mindset from preserving equipment to preserving the functions that equipment provides. United Airlines leaders Bill Mentzer, Tom Matteson, Stan Nowland, and Harold Heap evaluated maintenance strategies for the Boeing 747 jumbo jet, which was three times larger than the 707 and required new risk-based decision trees. You must follow four core principles during this analysis:

• Preserve system function by understanding expected output.
• Identify failure modes that can defeat the functions.
• Prioritize function needs and failure modes using a risk-based priority assignment rationale.
• Select applicable and effective tasks that prevent or mitigate failure, detect the onset of failure, or discover a hidden failure.

The Society of Automotive Industry JA1011 standard requires that your process answer seven essential questions before you can formally classify it as RCM. You must execute time-based preventive maintenance within 10% of the time frequency to remain in compliance.

Condition Monitoring Technologies

Condition-based maintenance evaluates asset health through periodic or continuous nonintrusive monitoring to perform maintenance just before performance drops. You rely on vibration analysis, infrared thermography, ultrasonic testing, oil analysis, and electrical testing to isolate problems through diagnosis. Proper lubrication management prevents catastrophic failures by following five strict rules:

• Select the right type of lubricant based on OEM manuals and supplier recommendations.
• Ensure the right quality of lubricant through proper handling and delivery storage.
• Deliver the right quantity to components, calculating grease using formula Q g = 0.114 D B.
• Apply the selected lubricant at the right place, labeling all lubrication points.
• Provide lubricant at the right time based on standard charts or OEM guidelines.

Over 50% of new incoming oil fails cleanliness specifications, which are classified using ISO 4406:99 standards. You must also monitor voltage imbalances, as a 5% imbalance in motor power circuits results in a 50% reduction in motor life expectancy and a 2.5% increase in temperatures.
