Crankcase Lubricating Oil
The Lubrication and Maintenance Charts list the normal oil change periods as determined by fuel sulphur content. (Make an initial oil change after the first 500 miles (750 km) of operation for reconditioned engines.)Use oils which meet Engine Service Classification CD, or MIL-L-2104C. These are additive-type oils approved for use in Caterpillar Diesel Engines. See LUBRICATION SPECIFICATIONS for recommended viscosity.Diesel Engine Crankcase
Check oil level daily before starting engine and when refueling. Check with the engine either running or stopped as indicated on the oil level gauge. Add oil when the level drops to the add oil mark. Drain the crankcase every 10,000 miles (16 000 km) while engine is warm and stopped. Drain the oil cooler if equipped with a Brake-Saver. If equipped with a 13 qt. (11 imp. qt.) (12 litres) supplemental filter system the normal interval can be extended to 12,000 miles (19 000 km). Install drain plug. Diesel Engine Crankcase Lubricating Oil Filters
Change filters. Unscrew and discard filter (right hand thread). Be sure to remove the old filter gasket. Clean the filter base with a clean rag. Put a thin coat of clean engine oil on the new filter gasket and install the new filter. Tighten the filter by hand until the gasket contacts the base, then tighten 3/4 turn more. Clean and install drain plug. Fill crankcase plus additional oil for auxiliary filter if so equipped. See SPECIFICATION for quantity. Run engine until oil is warm and check for oil leaks at drain plug and oil filter base. Check oil level to be sure it is at the full mark on the dipstick. Diesel Engine Crankcase Breather
Remove breather tube cover and element. Wash with clean solvent or diesel fuel every 30,000 miles (48 000 km) or 600 service hours. Inspect seal and install a new one if necessary. Lubricating Grease
Use Multipurpose-type Grease (MPGM) which contains 3-5% molybdenum disulfide conforming to MIL-M-7866, and a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures. Use NLGI No. 0 or No. 1 Grade for extremely low temperatures.Always clean fittings before lubricating.Fan Pulley Bearing
Lubricate every 10,000 miles (16 000 km). Lubricate through fitting until grease appears at relief fitting on front of fan hub. Wipe off excess grease. Water Pump Bearing
Lubricate every 10,000 miles (16 000 km). Lubricate through fitting until lubricant appears at relief fitting. Earlier engines have no relief fitting. Excess lubricant will appear at end of water pump shaft. Tachometer Drive
Lubricate every 10,000 miles (16 000 km). Remove plug. Install grease fitting and apply one stroke of lubricant through fittings. Governor Control Linkage
Lubricate every 10,000 miles (16 000 km). Apply one stroke of lubricant through fitting.
