Jules’ favorite bike 1928 101 Scout

[FLFD7]

Just a FYI for those working on 101s, the cork seal that Greer sells for the drive gear on later Chiefs fit the 101…

After installing that seal I have found it necessary to sand the seal down,or pre crush in a vise until the protrusion is less than flywheel side play,otherwise it will pull the flyweel against case,causing binding and early sprocket shaft thrust washer wear.
I don't think the seal really does much if your flywheel assembly is moving side to side.Probably the large sprocket washer does more.

I've discovered the best way to manage that cork seal is to eliminate it! Install a 1/8" wide lip seal at the outboard edge of the race. This will then require the spacer for the bearing cages to be turned down narrower, to allow room for the bearing cages. Yes, it moves the outboard bearing inboard by 1/8" but that does not matter. Having a good seal is important, otherwise the primary drive / transmission oil can mix with engine oil, or visa versa. Greers sells a setup for the chief like this but I don't know if it will fit the Scout.

...with the lip seal you'll have to split the cases to replace it?
