Information:
You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Engine Crankcase
Make sure you read and understand the information in the Lubricant Specifications section of this manual before you proceed with maintenance of the crankcase lube system.
Check Oil Level
The vehicle must be parked on a level surface to perform this maintenance procedure.
1. Check the oil leve with the engine stopped. 2. Maintain the oil leve between the ADD and FULL marks in the FULL RANGE zone on the ENGINE STOPPED side of the dipstick. Do not fill the crankcase above the FULL RANGE zone. Operating your engine when the oil level is above the FULL RANGE zone could cause your crankshaft to dip into the oil. If this happens, the air bubbles created from the crankshaft dipping into the oil will reduce the lubricating characteristics of your oil and would result in the loss of power.If the dipstick does not have a FULL mark in the FULL RANGE zone, refer to calibrating the oil level gauge in the Dipsticks section of this manual or consult your Caterpillar dealer before operating the engine. 3. Add oil if necessary. See Refill Capacities and Lubricant Specifications for the size of your engine crankcase and proper oil to use. Remote mounted or auxiliary filters require additional oil. For all information pertaining to auxiliary filters, refer to the OEM or manufacturer's instructions.Leaks and Loose Connections
Inspect the Engine
For maximum service life of your truck engine, make a thorough under the hood inspection before starting the engine. Look for such items as oil or coolant leaks, loose bolts, worn fan belts, loose connections and trash build-up. Remove trash build-up and have repairs made as needed.Keep a close watch for leaks. If leaking is observed, find the source and correct the leak. If leaking is suspected, check the fluid levels more frequently than the recommended intervals prescribed in this publication. Continue monitoring fluid levels until a leak is found and fixed, or until the suspicion for a leak has been proven to be unwarranted.* Wipe all fittings, caps and plugs before servicing. * Inspect the radiator for leaks and trash build-up. * Inspect the radiator hoses for cracks and loose clamps. * Inspect the fan and accessory drive belts for cracks, breaks or other damage.Belts for multiple groove pulleys must be replaced as matched sets. If only one belt of a 2 or 3 belt set is replaced, it will carry more of a load than the belts not replaced since the older belts are stretched. The additional load on the new belt could cause it to break. * Inspect the water pump for leaks. Check weep hole for water pump breather filter, 4N1400 (1), blockage and replace if necessary. * Inspect the engine for oil leaks, such as front and rear crankshaft seals, oil pan, oil filters and valve covers. * Inspect the fuel system for leaks, loose fuel line clamps
