Location of the transmission oil pump (4) Transmission oil pump. | |
Transmission oil pump (4) is mounted on the left side of torque converter housing (1) under the cab.
Transmission oil pump (4) is a positive displacement type pump. The one-section gear pump is bolted to the torque converter housing (1). The following pumps are mounted on the transmission oil pump (4) and driven by the transmission oil pump: steering pump, implement pump and pilot/brake pump.
The pump drive gear is fastened to the torque converter impeller. The pump drive gear drives transmission and hydraulic pump drive gear (2). Transmission and hydraulic pump drive gear (2) is fastened to pump drive flange (3). Pump drive flange (3) is connected to transmission oil pump (4) by splines. The splined shaft of the transmission oil pump drives the transmission oil pump.
