I am replacing the left and right timing chain cassettes.
Should I replace the jackshaft sprocket?
Chain, guide, & tensioner is a given - just wondering about the sprockets.
Also, what about the balance shaft chain and sprockets.
thanks,

I'm in the middle of replacing my cassettes and I did not replace that sprocket. Mine looks new - clean teeth - no chips etc.

Replaced mine when I did it. Had to order one back then as they weren't included with the kits. I was more worried of wear in from the old chain.
