I'm having a problem installing the primary chain. At the compensating sprocket the chain is .070 - .080 further out then at the clutch. This is
without any shim washers between the the extension shaft and rotor.
I have checked and rechecked to be sure that the sprocket and extention
shaft are seated properly and are tighten down. The stator rotor is a
Spyke 432410 (heavy duty). Between the rotor and stator I am using
a .090 shim washer which seems to be the rule with most motors. Can
this be my problem! Help!!

Correct me if I'm wrong, but I believe the style your working with is probably a BDL and non adjustable. If everything was wearing fine before, just get it on there. You need the .010" just to get it on. It will break if it's too tight. I also suggest getting another belt for the shelf. They're not hanging around at the local shop and this won't be the last time it goes.

.090? Are you sure it is an .090? I list only .001-.021 used as needed to get a less than .030 offset inside or outside.

I do not remember ever using a .090 on the inner spacer. If you are .070-.080 out and you do have a .090 then use a .010 only.

i didnt use a spacer behind the rotor. its beveled. but i did use a 20 between the shaft and the rotor. will this be ok?

You are correct. I removed the spacer between the rotor and stator and
checked the clearances. There is .250 from the end of the rotor to the
motor and stator wires. I installed the primary chain and took measurements.
The chain at the comp. socket is now .010-.012 further in then at the clutch.
Bingo!!! A .010 shim will do the trick. I can't believe the the chain has to
run that close in tolerance? Thanks
