OM4064 06/11 Maintenance - Section 40 Lubrication and Service Page 40-3 RESERVE ENGINE OIL SYSTEM (IF EQUIPPED) Oil should always be visible in the bottom sight gauge. If not, add oil to the reserve oil tank until oil is visible in the top sight gauge. The reserve oil tank for the engine is designed to add more oil capacity to the engine to reduce the frequent servicing of the engine oil. The engine oil level must still be checked every shift using the dipstick. If engine oil level is not correct, check for proper operation of the reserve oil system. Never add oil to the engine unless it has been drained. Never add oil to the engine unless it has been completely drained.
If the engine oil has been drained from the oil pan, new oil must be added to the oil pan. Do not use the oil in the reserve oil tank to fill an empty engine oil pan. If the engine oil has been drained from the oil pan, the new oil must be added to the engine oil pan before starting. DO NOT use the oil in the reserve tank to fill an empty engine with oil. After an oil change, both the engine and reserve tank must be full of oil before start- ing the engine. After an oil change, both the engine and reserve oil tank must be full of oil before starting the engine. Reserve Oil Tank Filling Procedure (Remote fill) 1.
Connect the pressure supply hose from the new oil supply to the quick coupler on the truck. Open valve on supply hose to apply pressure. With the engine running, check the operation of the red LED light on the pump. 2. Pull out on switch (2, Figure 40-3) to turn the sys- tem on. Continuously on - Pump 1 is withdrawing oil from the engine sump and bringing down the oil level. 3. Push start switch (3). The VALVE OPEN light (5) should illuminate and the filling process will begin. Regular pulsing - Pump 2 is returning oil to the engine sump and raising the oil level. 4. When tank is full, the VALVE OPEN light will turn off and FULL light (4) will illuminate.
Irregular pulsing - Oil is at the correct running level. 5. Close the oil supply valve in the fill hose. 6. Press and hold start switch (3) for a couple of sec- onds. 7. Disconnect the new oil supply hose. 8. Push switch (2) in to turn system power OFF. NOTE: Maximum recomended fill pressure for the reserve oil system is 862 kPa (125 psi) Inline Screen There is an inline screen located at the inlet of the fill valve. This screen does not require periodic mainte- nance, but it can be cleaned by removing the screen and back flushing. FIGURE 40-3. CONTROL PANEL 1. Remote Control Box 2. Power Switch 3.
