OM4041 08/11 Lubrication and Service - Section 40 Page 40-11 RADIATOR FILL PROCEDURE Check oil level again, as described below, when transmission oil reaches operating temperature. 2. Engine Running: The cooling system is pressurized due to thermal expansion of coolant. DO NOT remove the radia- tor cap while the engine is hot. Severe burns may result. The oil level must be visible in lower part of sight gauge (turtle) between "H" and "L". Check transmission oil level with: • truck parked on level surface, • engine running at low idle, • transmission in neutral, "N", and • transmission oil at normal operating temperature: 1.
With the engine and coolant at ambient temper- ature, depress the pressure relief to remove cooling system pressure. Slowly, remove the radiator cap. NOTE: If coolant is added using the quick fill system, the radiator cap must be removed prior to adding coolant. Add clean oil as required through transmission oil filler tube at left rear of transmission. 2. Fill the radiator with the proper coolant mixture as specified by the engine manufacturer. Fill until coolant reaches the radiator cap area. HYDRAULIC TANK SERVICE 3. Install the radiator cap. Filling Instructions 4. Allow the engine to idle for 5 minutes. Shut the engine off and wait for the engine to cool. 1.
Lower the dump body, shut down the engine, and turn the keyswitch OFF. 5. Check the coolant level. If the radiator is not full, repeat the previous steps. Any excess coolant will be discharged through the vent hose after the engine reaches normal operating tempera- ture. Hydraulic tank may be pressurized! Depress relief valve (2, Figure 40-2) and release hydraulic tank filler cap slowly to remove any internal pres- sure. TRANSMISSION OIL LEVEL CHECK 2. Depress relief valve (2, Figure 40-2) for 30 - 45 seconds to release any internal tank pressure. Turn the oil filler cap (4) slowly counterclock- wise to release any possible residual tank pres- sure. 3.
Refer to Lubrication Chart, Lube key "C". Fill tank with recommended oil, until oil is visible in upper sight glass (5). NOTE: If hydraulic tank has been completely drained, refill capacity is: 576 liters (152 gal.) 4. Replace fill cap. 5. Start the engine, and raise and lower dump body 3 times to circulate oil and fill all lines, valves, cylinders, etc. 1. Engine Stopped: Oil level must be visible in upper part of sight gauge (STOP) between "H" and "L" to be sure there is sufficient oil to safely operate transmis- sion when engine is stopped, or if transmission oil is cold (engine has been stopped for 8 hours or more). 6.
Repeat steps 1 through 5 and fill until oil level is again in upper sight glass (5). 7. If oil level falls below lower sight glass (6) with engine running, repeat Steps 1 through 5.
