Most likely this is a common commutator style DC motor and the brushes are worn down quite a bit or there is a bad spot on the armature. When Randy taps the motor with a hammer, it is making the brushes in the motor shift and come into contact with the armature or it is causing the armature to shift slightly moving one or more of the brushes off the bad spot. In a lot of cases, motors like these are not setup to be repaired in the field since the cases are sealed o keep out the weather and one has to open them like a can to get to the internals. So a field overhaul is just not possible. One can only swap out the motor as a complete unit like Randy had to. Killer deal on finding the cross over part. I have had to do the same thing with my vette a couple times.
I am sure I will face this same project one day soon as well. I pick up my 95 Destiny M400SI next friday. Drop me a PM about the manual you have. I think I am going to definately need it. Nice write up on the repair, photos, and documentation Randy!
The OP's repair is neat, but, as described above the DC motor brush/armature contact gets worn out. On mine, I took the motor off the gear box, rotated the armature a bit, and put it back together. It's ran fine for 3 years now. The reassembly of the motor, that is, keeping all those small parts in the right place to get it back together was tedious, but very possible. If doing it again and knowing that the assembly was available for <$50, I would probably buy it.
