Title: B31 Engine sprocket shims
Post by: chrisgoodwin on 17 September, 2017, 21:32:36
Hi all,
I need some advice (again) & I wonder if anyone out there can help.

I need to align the engine sprocket to the clutch chain wheel and I am looking for some suitable shims. I can see shim kits for an A7 and I suspect they would also fit the B31, searches for specific B31 aligning shims seems to draw a blank.

Does anyone know if the A7 shims would fit, or where I could obtain specific B31 shims.

I have a 4 lobe spring shock absorber and I think I need to move the sprocket out about 30 tho (ish)

Thanks in advance,
Chris

I really don't think thirty thou out is anything to worry about , when you think of the distance between the two sprockets, this is quite acceptable.
