Joints and joint faces

Joints and joint faces

Fit joints dry unless specified otherwise.

• When jointing compound is used, apply in a thin uniform film to metal surfaces; take care to prevent jointing compound from entering oilways, pipes or blind tapped holes.
• If gaskets and/or jointing compound is recommended for use; remove all traces of old jointing material prior to reassembly. Do not use a tool which will damage the joint faces and smooth out any scratches or burrs on the joint faces using an oil stone. Do not allow dirt or jointing material to enter any tapped holes or enclosed parts.
• Prior to reassembly, blow through any pipes, channels or crevices with compressed air.

Locking Devices

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 -

Always fit new split-pins of the correct size for the hole in the bolt or stud. Do not slacken back nut to enter split-pin.
