Today I modified a C clip.
The inner clutch circlip onto the crank.
It got a lil loose, and bending wasn’t allowing it to really grab the crank anymore, the ends would bump together! So I cut a touch off each end before the grabbin holes, cut with a dremel cutting wheel. Now it’s nice and snug on the crank. Also was cupped a bit but a few whacks with the baby sledge on an anvil and it was flat again.
As well, when positioning the stock clutch bell hub thing, I use a mini screwdriver to get the outer circlip into its groove. I press it in hard using the crank as leverage to make sure it’s seated. It often it looks like it’s in, but it ain’t IN until you push it in.
That’s what he said (edited)
