Locking Devices

Locking Devices

General
Always replace locking devices with one of the same design.

Tab washers
Always release locking tabs and fit new locking washers. Do not re-use locking tabs.

Locking nuts
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.

Split pins

Split Pins:

Always fit new split-pins of the correct size for the hole in the bolt or stud.
