I - Preventive Maintenance Flashcards
True or False: Breakdown maintenance is a system of maintaining a machine whereby components are replaced on a regularly scheduled service interval.
False; Breakdown maintenance refers to the policy of running a component or machine until something breaks. At that time replacement occurs.
Identify hidden costs that can occur if a system of breakdown maintenance is followed.
Unexpected equipment downtime, secondary component damage, reduced equipment life, and higher overall cost, and high operator and/or technician turnover.
Component failure and damage can be classed as primary and secondary. Explain what effect secondary damage may have on a machine.
Secondary damage could raise the cost of the primary component failure considerably. Numerous sub-assemblies may be damaged because of the primary failure. The extensive damage could increase the amount of time the machine is down for repair.
Preventive and predictive maintenance systems attempt to reduce the number of unexpected breakdowns.Identify 5 purposes of a predicative maintenance system.
Maintain component reliability at a like-new standard, reduce the possibility of unexpected component failures, increase component operating service life while reducing operating costs, increase equipment safety and dependability, increase the value of a machine on trade-in or re-sale, or meet the service requirements necessary to maintain a manufacturer’s parts warranty or any extended warranty.
A preventive or predictive maintenance system requires information about the machine. This can include such things as machine identification and the service work done on various components. The information could be recorded on a/an:
Computer managed maintenance system, parts department card system, service department card system, or accounting department card system.
True or False: Off-road machines are often shut down for maintenance after so many hours of operation.
True.
A system of predictive maintenance attempts to predict or anticipate when a component may fail. This prediction is based on a manufacturer’s suggested recommendations regarding component life span. Identify 4 other information collection systems that can be used to help make better predictions about component life span and failure.
Oil analysis and oil filter contamination, vibration analysis, heat detection, and component life history.
A predicative maintenance system where components are replaced at regularly scheduled service intervals has several advantages. What are the advantages?
Increased productivity, reduced maintenance costs, reduced emergency and breakdown time, reduced secondary damage, and aids in scheduled maintenance.
True or False: A regularly scheduled oil analysis program does not help you predict component problems, long before failure occurs.
False; An oil program can definitely assist you in predicting component failure. Regular monitoring, and careful interpretation of the oil analysis results, helps predict component failure far in advance of the actual failure.
True or False: A careful, conscientious, observant and alert service technician is required to make a success of any preventive maintenance program.
True.
