Sachs shimming

[John Ehrhart]

What a great site to find! Now I don't feel like I am the only one with these bikes hanging out in the garage any more.
I am getting the Monark back together after a center case gasket replacement and have a problem. The snap ring holding the shift drum will not seat. Makes it a bit difficult to adjust the shifter!
I can't tell from the Sachs manual exactly which side of the drum the shims should reside--and it's been about twenty years since I last split this this thing. Can anyone direct me?
Thanks in advance for your help!
