TM 9-2360-261-20-1 OIL COOLING SYSTEM COMPONENTS — ENGINE, TRANSMISSION, AND DIFFERENTIAL The engine, transmission and differential oil cooling system keeps the oil clean and within proper operating temperature range. The components of the system and their functions are: Engine, transmission, and differential oil cooler unit (1) is mounted on the engine. By circulating the hot oil through this unit, heat is given off to the surrounding engine coolant. Engine coolant is in turn cooled by the engine cooling system (page 2-3). Oil cleanliness is maintained by circulating engine oil through the engine oil filter (2), and differential oil through the differential oil filter (3). Transmission oil is cleaned by the transmission oil filter which is an integral part of the transmission. Differential oil pump (4) is mounted on the transfer gearcase. It pumps oil from the bottom of the differential housing and to the differential oil filter (3). Oil flows through filter (3), through cooler (1),and back to top of differential (5). 2-11
