Always use a backing spanner when loosening or tightening locking nuts, brake and fuel pipe unions. - Roll Pins
Always fit new roll pins of an interference fit in the hole. - Circlips
Always fit new circlips of the correct size for the groove. - Keys and keyways
Remove burrs from edges of keyways with a fine file and clean thoroughly before attempting to refit key.Clean and inspect key closely; keys are suitable for refitting only if indistinguishable from new, as any indentation may indicate the onset of wear.
