I have a 95 ford f 150 with manual transmission I changed the starter motor and found it was off of a 98 ford van and now the starter wont disengage after I start the truck what causes this problem
Different nose size of the starters.
I take it you still have both starters. As shoes said check the nose size on both starters. Then check the gear width and depth on the two starters for sameness. If the gear on the starter is being forced into the cogs on the flywheel they will not disengage.
