66-3081 Kickstart pinion Bush.

24-4281 

BSA M20, M21, B33

These have been made in two different materials.  This one is with PB1.

The BSA fitting instructions are quite clear about not crushing this fragile bush. 

If it swells it will weld itself to the pinion gear. 

So, make sure you use the correct nuts and tab washer. 

Also, as in many applications this bush runs in a dry environment it might be better to grease it rather than use oil.
