Remove and replace motorcycle combustion engine units and components
URN: IMIMC02
Business Sectors (Suites): Maintenance and Repair - Motorcycle
Developed by: IMI
Approved on:
2021
Overview
This standard is about removing and replacing motorcycle combustion engine units and components previously identified as faulty, damaged, deteriorating or where a customer has requested a replacement, where dismantling and re-assembly of engine systems is required. It is also about evaluating the performance of replaced units and components. The units and components concerned are those not replaced as part of normal routine, motorcycle maintenance (servicing) activities.
In this standard the term ‘motorcycle’ includes motorcycles, scooters, mopeds and motorcycle-derived vehicles with three or four wheels (such as quad bikes) on which the rider sits.
Performance criteria
You must be able to:
P1 use suitable personal protective equipment and motorcycle coverings (where applicable) throughout all removal and replacement activities
P2 ensure the motorcycle and the work area is safe prior to work commencing
P3 support your removal and replacement activities by reviewing:
P3.1. motorcycle technical dataP3.2. removal and replacement proceduresP3.3. legal requirementsP4 prepare, check and use all the equipment required following manufacturer’s instructionsP5 carry out all removal and replacement activities following:P5.1. manufacturer’s instructionsP5.2. industry recognised repair methodsP5.3. your workplace proceduresP5.4. health, safety and environmental requirementsP6 work in a way which minimises the risk of:P6.1. damage to other motorcycle systems, units and componentsP6.2. contact with leakage and hazardous substancesP6.3. damage to your working environmentP6.4. injury to self and othersP7 ensure replaced combustion engine units and components conform to the motorcycle operating specification and any legal requirementsP8 promptly record and report any additional faults you notice during the course of your workP9 use suitable testing methods to accurately evaluate the performance of the reassembled system
P10 ensure the reassembled combustion engine system performs to the motorcycle operating specification and meets any legal requirements prior to return to the customerP11 ensure your records are accurate, complete and promptly passed to the relevant person(s) in the format requiredP12 complete all removal and replacement activities within the agreed timescaleP13 promptly report any anticipated delays in completion to the relevant person(s)
