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.

P3 support your removal and replacement activities by reviewing:

P3.1. motorcycle technical data
P3.2. removal and replacement procedures 
P3.3. legal requirements
P4 prepare, check and use all the equipment required following manufacturer’s instructions
P5 carry out all removal and replacement activities following:

P5.1. manufacturer’s instructions
P5.2. industry recognised repair methods
P5.3. your workplace procedures 
P5.4. health, safety and environmental requirements
P6 work in a way which minimises the risk of: 

P6.1. damage to other motorcycle systems, units and components
P6.2. contact with leakage and hazardous substances
P6.3. damage to your working environment
P6.4. injury to self and others
P7 ensure replaced combustion engine units and components conform to the motorcycle operating specification and any legal requirements
P8 promptly record and report any additional faults you notice during the course of your work
P9 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 customer
P11 ensure your records are accurate, complete and promptly passed to the relevant person(s) in the format required
P12 complete all removal and replacement activities within the agreed timescale
P13 promptly report any anticipated delays in completion to the relevant person(s)
