cork washer or not inbetween camshaft pinion/breather, longstroke

[chicago]

hi folks, just a quick question before i put my case's back on. on a 1947 longstroke engine, should there be a cork/felt washer inbetween the camshaft pinion and the breather ?.

as there isnt one on mine and as ive gathered this washer is supposed to eliminate end float on the cam ?.
cheers in advance fella's, all the best, chicago

Hi.
Should be cork washer between pinion and breather, different sizes available to correct end float.

Hi
It is very important to fit the cork washer, its a necessary part of the timed breather !!
The thickness of the washer should be the next thicker one than one that allows zero endfloat on the breather sleeve, so its compressed a bit when the case is tightened up
It does NOT control endfloat of the cam.
