A lubrication technician notices that oil analysis results for a gearbox show a sudden spike in iron particle count. Which corrective action should be prioritized first?
Answer: Perform a follow-up sample to confirm the trend before escalating
A follow-up sample confirms whether the spike is a real trend or a sampling anomaly before costly actions are taken.
In a Kaizen event focused on lubrication routes, which metric best measures the success of the improvement?
Answer: Reduction in lubrication-related downtime and route completion time
Kaizen success in lubrication is measured by tangible gains such as reduced downtime and more efficient route execution.
Which statistical tool is most appropriate for identifying the root cause of lubricant contamination events occurring at different frequencies across multiple machines?
Answer: Pareto chart
A Pareto chart ranks contamination sources by frequency, helping prioritize the most impactful corrective actions.
A facility wants to standardize lubricant storage to reduce cross-contamination risk. Which color-coding system element is most critical?
Answer: Assigning a unique color to each lubricant type and applying it consistently to all dispensing equipment
Consistent color coding applied to all dispensing tools, containers, and fittings prevents accidental mixing of lubricants.
Which approach best supports a continuous improvement culture in a lubrication program?
Answer: Using a PDCA (Plan-Do-Check-Act) cycle for routine lubrication tasks
PDCA provides a structured iterative framework that embeds continuous improvement directly into daily lubrication practices.
During an oil analysis review, a hydraulic fluid sample shows a viscosity 15% below specification. What is the most likely cause?
Answer: Fuel dilution or solvent contamination
Fuel or solvent dilution lowers viscosity significantly by thinning the base oil, making it a primary suspect when viscosity drops below spec.
A facility implements ISO 16232 cleanliness standards for hydraulic systems. What does achieving a target cleanliness code primarily prevent?
Answer: Abrasive wear and valve malfunction caused by solid particle contamination
ISO cleanliness codes target solid particle contamination, which is the leading cause of abrasive wear and hydraulic component failures.
