Torque converter and pump drive housing

(1) Torque converter

(2) Torque converter housing

(3) Drive gears (steering and implement)

(4) Pumps (steering and implement)

(5) Idler gear

(6) Output yoke (transmission)

(7) Drive gear

(8) Drive gear

(9) Drive gear (transmission oil pump)

(10) Transmission oil pump

Transmission oil pump (10), steering pump (4), and hydraulic implement pump (4) are mounted on torque converter housing (2). Torque converter housing (2) is mounted on the engine flywheel housing.

Gear (8) turns drive gear (9) for transmission oil pump (10). Gear (7) turns idler gear (5). Idler gear (5) turns drive gears (3) for steering pump (4) and implement pump (4). Torque converter (1) turns output yoke (6). Output yoke (6) sends power to the input transfer gears of the transmission.
