Transmission

Transmission — Power Director

Transmission	Power Director
Type	partial power shift
Gears	12 forward and 3 reverse
Clutch	12-inch dry disc (main)
	7-inch wet discs (power shift)
Oil capacity	26 qts 24.6 L
Four forward gears and one reverse combined with three-range power shift between low, direct, and overdrve. Used on the maroon-chassis model 7000. Power shift was similar to the Allis Power-Director system, with a third clutch added to provide an overdrive.

Transmission — 12 forward and 3 reverse partial power shift

Type	partial power shift
Gears	12 forward and 3 reverse
Four forward gears and one reverse combined with three-range power shift between low, direct, and overdrve. The black-chassis Allis 7000 used a new hydraulic wet clutch and torque limiter. A combination clutch/inching pedal put the transmission into low range when depressed.
