RESTORATION
STAGE 6 - SWING ARM
The swing arm was in good condition however the bearings needed replacement.
Bearings - removed
The swing arm was placed on it's side over a block of wood so that the bearing tube overhangs the block. A round bar is used to tap the bearing out, I used a 30cm piece of concrete reo bar with the end filed flat.
Start at 12 O'clock go to 6 O'clock then to 9 O'clock then to 3 O'clock so that the bearing is tapped out straight if it becomes skewed tap it straight then continue.When the first bearing is removed the spacer tube will drop out then the second bearing can be removed.
The swing arm & spacer tube were degreased.
New Bearings - installed
The swing arm was then clamped in the vice with the bottom of the bearing tube resting on the bottom of the vice so that it can not move down while the new bearing is being tapped in.
A piece of flat hardwood was used to start the bearing off then an appropriate size socket was used to drive the bearing home, the force applied with the socket should be applied to the outside race (outer edge) of the bearing or it will be damaged on installation.
The swing arm is then turned over and the spacer is placed in the bearing tube then tap the second bearing in, the flat washers & dust covers can now go on after applying a little rubber grease to the outer edge of the seal as this moves on the swing arm. Are We There Yet.
Charin Guard Tab
At some point in it's life the chain guard tab had snapped off so the remainder was filed flat & a new one fabricated from a piece of 4mm flat bar the welded in place.
