There are 2 slightly different American Bosch motor styles used in the landing gear system. The difference – one has a cast end housing and one a stamped end housing. The motors are interchangeable, however some internal components are not. Some trivia – in the July 1960 Piper parts price list this motor was $17.13; my motors are a modest $575. I can give references for this same motor for $800 and another $1,000.

New field coils, rewound and dynamically-balanced armature, and cadmium-plated housing. Looking better than new.
Stamped-type end housing American Bosch motor; click on the photo for a look at a “finished” motor and brake coil.

I stock landing gear motors which have been remanufactured by an FAA repair station; they have the 8130 forms. For you overseas customers this seems to be the “cleanest” approach to your documentation problem. Since there is no mention of servicing these motors in the Piper Comanche service manuals we are either to ignore any un-approved service or bite the bullet and pay the fiddler.
