OM4015.1 Maintenance - Section 4 Lubrication and Service Page 4-1 LUBRICATION AND SERVICE Preventive Maintenance will contribute to the long life and dependability of the truck and its components. The use of proper lubricants and the performance of checks and adjustments at recommended intervals is most important. The service intervals presented here are in hours of operation. These intervals are recommended in lieu of an oil analysis program which may determine different intervals . However, if truck is being operated under extreme conditions, some or all, of the intervals may need to be shortened and the service performed more frequently.
Lubrication requirements are referenced to the lube key found in the Truck Lubrication Specifications Chart. For detailed service requirements for specific components, refer to the service manual section for that component (i.e. Section “H” for Suspensions, Section "L" for Hydraulic System, etc.). Many Haulpak Trucks are equipped with an optional Automatic Lubrication System. The initial setup for this system provides for nominal amounts of lubricant to be delivered to each serviced point. The lubrication injec- tors can be adjusted to vary the amount of lubricant delivered. In addition, the timer for lubrication intervals is normally adjustable.
Consult the "Options and Ac- cessories" section of the truck service manual for ad- justments to these devices. Refer to manufacturer’s service manual when servicing any components of the General Electric System. Refer to engine manufacturer’s service manual when servicing the engine or any of its components. HYDRAULIC TANK SERVICE There are two sight gauges on the side of the hydraulic tank. With engine stopped, keyswitch "off", hydraulic system bled down and body down, oil should be visible in either top or lower sight gauge. If hydraulic oil is not visible in the lower sight gauge, follow "Adding Oil" instructions below.
Adding Oil Remove any dirt build-up around fill cap and breathers and clean fill area thoroughly before removing fill cap. To reduce chances of system contamination, DO NOT allow the system to be open to atmosphere any longer than absolutely necessary . Service the tank with clean Type C-4 hydraulic oil only. All oil being put into the hydraulic tank should be filtered through 3 micron filters. 1. With engine stopped, keyswitch "off", hydraulic system bled down and body down, check to see that hydraulic oil is visible in the top or lower sight gauge. 2.
If hydraulic oil is not visible in the lower sight gauge, remove the tank fill cap and add clean, filtered C-4 hydraulic oil (Lubrication Chart, Lube Key "D") until oil is visible in the top sight gauge. Replace fill cap. 3. Start the engine, then raise and lower the dump body three times. Shutdown engine. Check for hydraulic oil level at the top sight glass. 4. If oil is not visible in top sight glass, repeat Steps 1 through 3, until oil level is maintained in the top sight glass with engine stopped. 630E/685E SERVICE CAPACITIES Engine Crankcase: (including lube oil filters).
