Right Side of Engine (1) Axle Oil Cooler Pump and Clutch.Axle oil cooler pump and clutch (1) is mounted on a bracket at the front of the engine above the damper. The axle oil cooler pump and clutch is powered by the engine crankshaft via a V-belt that is driven by the damper pulley. The axle oil cooler pump is a two-section gear pump. The pump that circulates the oil for the front axle housing is mounted closest to the damper. The tandem mounted pump circulates the oil for the rear axle housing.

Front View of the Rear Axle (2) Rear axle center housing. (3) Temperature switch.Axle oil cooler pump and clutch (1) is activated when the contacts of temperature switch (3) close. The contacts for the temperature switch close when the axle oil reaches the actuation temperature of the switch. The actuation temperature of temperature switch (3) is 65° 3°C (150° 37°F). When the contacts of temperature switch (3) close, the electric clutch on the axle oil cooler pump and clutch is energized. The temperature switch is installed in a manifold block at the center of the rear axle housing.

Front of Engine Frame (4) Axle oil cooler. (6) Bypass check valves for the axle oil cooler .When the electric clutch is energized the pumps circulate the axle oil through separate systems for each axle housing. The oil is pumped through passages in both the front axle housing and the rear axle housing. Each gear pump causes the oil to flow through hoses to axle oil cooler (4). The axle oil cooler is installed between the frame rails of the machine in front of the rear axle. While the axle oil flows through the axle oil cooler, engine coolant also flows through the axle oil cooler. The axle oil cooler performs two functions. The engine coolant cools the axle oil that flows through the axle oil cooler if the temperature of the axle oil is higher than the normal operating temperature. The axle oil cools the engine coolant that flows through the axle oil cooler if the engine coolant temperature is higher than the normal operating temperature.

Hose Assemblies for the Axle Oil Cooler (5) Coolant hose assemblies. The engine coolant flows through coolant hose assemblies (5) to the axle oil cooler and flows back to the engine through coolant hose assemblies (5). The flow of the axle oil through the axle oil cooler helps keep the axle housings and internal brake components cool.Two bypass check valves for the axle oil cooler (6) are located at the axle oil cooler. The bypass check valves limit the oil pressure in the oil cooler core. The bypass check valves are rated at 448 55 kPa (65 8 psi). If the bypass check valves open, the axle oil bypasses the axle oil cooler.
