The “overhauled” motor is available separately for $675 exchange, see below. These motors have new field coils, rewound and dynamically balanced armature, new Kevlar pole shoe insulators, new springs and/or brushes as necessary, repaired brush holders as necessary, MIL-Spec wires, properly re-impregnated Oilite® bearings, and the housing has been cadmium plated. This is as close to new as you can get, maybe even better.
After installation of your new transmission, ship your exchange but preferably within 2 weeks; I need the motor and release components for refurbishing.
Compare this to an exchange Dukes transmission if you can find one [I may have them available], which may not have any new components. I sold an original Dukes for $5,500 in 2020, which is the price that I was offered.
FWIW I have every component to repair the Dukes transmissions; all of my new transmissions use the latest Dukes specification gears set, not the original steel version. The bearings I use are SKF [Italy] and Nachi [Japan], no chinesium stuff here.
This dukes-type Piper Comanche landing transmission basic assembly P/N 25720-003 as shown below is $3,850 exchange, plus shipping and insurance. The black and red components are powder coated the other pieces are cadmium plated; also includes new placards. The updated bushing [safety issue] P/N 21038-007 is included, also owner produced.
If you have a new or guaranteed good motor, this transmission version is what you need. Install your motor and brake and you’re back in business.
I hear a lot of, “Oh my motor is just fine.” Really? And who tested it with an insulation tester to determine that? Bad insulation leads to increased heat and current draw, sometimes adding to the 30-amp motor circuit breaker to open upon retraction
