Finishing work
NOTE:
The gasket may only be re-used once. Check whether there is a 2 at the top of the right-hand corner of the gasket. The gasket must be replaced if there is a 2 on it. If there is no digit, stamp a 2. This indicates that the gasket has now been reused and must be replaced the next time the side cover is removed. Make this mark to assist other mechanics.
Replace the old rubber gasket which seals around the drive shaft.
