Chain Tangle!

[wrongway]

As I’m pedaling I can hear a ‘thump’ sound as the chain (I suppose it’s the chain) drags or catches.

sounds like an economy asian drive chain, Walmart?

I figured out the thumping, dragging

chain. The cotter had worked loose ever so slightly sending two of the three bolt heads into the frame. Now, to see if that is what caused the chain to come off the track. It works nearly flawlessly on the stand.

perhaps you need to make or purchase a cotter pin press to get them well seated

a c-clamp with a socket from a socket set can be used for both seating and removal:

Oddly enough I have no trouble taking them apart. I have a workbench vise that is not bolted down and a used hospital table to lay it on. With that combination I have no trouble removing them. I don’t usually think to seat them the same way.

if you ever reuse wedgebolts it is good to take a file and file down the old seating mark until it disappears

reusing pins without doing this can impair the seating...
