There are three low speed planetary gears in a cast aluminum carrier in the middle of the gear train. This system is driven by the spur gear on the small bell gear unit which is the output of the high speed planetary system.

The bearings in the Carrier are special, and there are no modern replacements for them.

The larger planet gears mesh with the ring gear that is mounted between the gearbox case halves. The smaller gears mesh with the large bell gear that contains the splined output tube.
