Delco Motor
27.5 vdc
(MOT) 71D166
Delco motor made by Halicrafters. Magnificent craftsmanship. Anti-backlash gears, tremendous torque. The Delco motor specs are 27.5 vdc @ about 100 ma unloaded. The tag on the motor states 2040 rpm CW & 1950 ccw. As you can see, it is in a shielded box. 25:1 Ratio between the two 1/4" shafts. Motor to primary shaft: 80:1, primary shaft to secondary: 25:1. 6" x 4-1/2" x 4-1/2"D including shafts.

Turn input shaft manually or engage motor and it will take over. That's how they were supposed to work but we have a few issues with it due to the fact that they are 60 years old. With motor engaged, output shaft runs at 1 rpm.

Although they are new in the box, the washer in the clutch has dried out and the motor will no longer engage the shaft.

We sell these for manual use only. If you get the motor assist to work, you're ahead of the game. Knobs pictured in movie are NOT included.
