Clutch spacer spring
 

I have a 108 Cub with a 126 rear end. I'm in the process of replacing the clutch. The previous owner did not use a spring spacer in the clutch. The parts list for a 108 lists part #20, spring spacer. The parts list for a 126 does not list a spring spacer, the clutch is shown set up like the PO had it. Do i need a spring spacer? The clutch I'm replacing uses every other part listed on the 108 parts list.
:bigthink:

You do not need the spring spacer. The drive shaft and location of the clutch release lever is different on a 108 than a 126.

The rear ends are the basicly the same. The clutch assembly is different.

First off, YES the transaxle is of NO consequence.

I may be confused, but if you are rebuilding a clutch that is going into a 108, then it is my belief that yes you do need the spring spacer. Otherwise when the clutch is released there will be little or no pressure on the rear pressure plate causing the clutch to slip or not make contact with the rear pressure plate at all.

The 126 does not use the spring spacer, however, the 108 does.

Thanks guys. I'm going to get a spring spacer. It's a 108 clutch, except for the fact it was missing the spacer. Something wasn't right with the previous set-up, the 3 pin clutch driver bushing was completely worn out of the driver. The PO used 2 nuts and bolts on the drive shaft coupling, not sure if that's what killed the bushing or not. I figure I should stick to the 108 clutch parts list.

I was confused..
You need the spacer if the clutch goes in 108.
You do not need the spacer if the clutch goes in a 126.

the pilot bushing would go bad any way. They are cheap and there is no easy way to keep it lubed up. Its commonly used even in cars. But not many cars went unserviced 40 years!
