Transmission Oil Cooler (1) Scavenger pump for OTG oil recovery (2) Oil cooler (2A) Top section of oil cooler that cools the transmission oil (2B) Bottom section of oil cooler that cools oil from the hydraulic arrangement | |
The oil-to-water type transmission oil cooler (2) is located beneath the front right-hand side of the operator station. The oil is cooled by coolant supplied by the engine cooling package.
Oil from the torque converter flow through a bundle of small tubes inside the cooler. The oil is cooled by engine coolant flowing around the bundle of oil filled tubes. The cooled oil enters the transmission lube oil circuit and drains into the transmission oil sump. The remainder of the oil is returned directly to the transmission oil sump.
Refer to Illustration 1.
Upper portion (2A) of the cooler handles the oil for the transmission and OTG. The lower portion (2B) handles oil from the hydraulic arrangement. The water lines from the engine cooling package flows through both sections of the cooler.
