starter Motor Problems

[horsa]

The end of the starter shaft stabs into a housing when you are installing it into the vehicle. The housing should have a bushing, probably brass, that should be an exact fit to the starter shaft. If it is wallowed out or missing, you might have some play going on and the thing is torquing over a bit and locking.

It's worth checking and while doing so, put a dab of grease into it if it seems OK.
