Engine Works 101 is in session...

The reason the crank stays in one place no matter what force is applied is called the thrust washer. There are 2 in the 22R series engines, one to hold it forward, and the other to hold it back.

If one or both are bad, the crank can walk forward and backwards if longitudinal force is applied. Depressing the clutch presses the flywheel forward, and can cause the crank to push outwards if the thrust washers are bad. Upon release of the pressure the crank will slam backwards, and usually past the starting point. This can cause the dust shield on the back of the crank pulley to rub against the oil pump housing. <img src="/forums/images/graemlins/kewl.gif" alt="" />
