Doesn't matter what the rest are really.
Time for a rebuild or replacement.

Depending on your situation it may be cheap to find a JY motor, but thats a bit doubtful.

Can you do it yourself?

You can do a basic re-ring but I'd suggest doing a complete rebuild.

Try your local machine shoips. You can usually get a package deal that includes machining and a rebuild kit.
