Hello Basis
I see the problem and frustration now,
The Supercuts had so many variants! mad

Your machine has the pulleys on the far R.H. side.

I feel the answer must be in moving the jackshaft (countershaft) to the left and
this requires disassembly of both sides.

I can't find a parts book that covers this.
Is it a conventional RH collar that secures the RH bearing?
I think it must be.

I hope a member can help.
It may be that you will help other folk down the track.
