When I tried to engage the pto, the lever broke off where it is welded to the collar. Since the collar is only pinned to the shaft it does not look to be a big deal to remove. But I also noticed that the shaft is spring loaded to jump back into the housing. My question is: how far in will the shaft retract when I drive the pin through the collar, and how to pull the shaft back out enough to put the collar and pin back on. Thanks.
