Walk-Around Inspection
Inspect Engine for Leaks and Loose Connections
A walk-around inspection should only take a few minutes of your time. By taking the time to make these checks, costly repairs and accidents can be avoided and your equipment will be ready to run should the need arise.For maximum engine service life, make a thorough inspection before starting the engine. Look for items such 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 maintenance intervals and continue to monitor fluid levels until any leak is found and fixed.* Wipe all fittings, caps and plugs before servicing to reduce the chance of system contamination. Inspect:* Radiator core for leaks and trash build-up.* Radiator and air inlet system hoses and elbows for cracks and loose clamps.* air-to-air aftercooler for insects, dirt and other debris. Clean as necessary. Clean the front of the aftercooler with a stainless steel brush and soapy water.Depending on your findings and operating environment, the maintenance interval for cleaning the air-to-air aftercooler can be extended from a Daily to an as needed basis.* 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 two or three 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.* Water pump for coolant leaks at weep hole. Check weep hole for water pump breather filter blockage. Replace the filter if necessary. The water pump seal is lubricated by coolant in the cooling system. It is normal for a small amount of leakage to occur as the engine cools down and parts contract.If leaks are found, check the coolant level frequently and continue to monitor the level until the water pump is repaired. Excessive coolant leakage may indicate the need to replace the water pump seal. For removal and installation of water pumps and/or seals, see the Service Manual for this engine or consult your Caterpillar dealer.* Lube system for leaks, such as front and rear crankshaft seals, oil pan, oil filters and valve covers.* Fuel system for leaks, loose fuel line clamps and fittings and loose or worn hoses.
Fuel line clamps should not be over torqued. Over torqueing causes the clamps to butterfly, which results in low clamping force, fuel line vibration and eventual failure. Refer to the Torque Specifications in this manual.
* Drain water and sediment from fuel storage and day tanks on a daily basis to ensure only clean fuel enters the fuel system.* Inspect wiring and wiring harnesses for loose connections and worn or frayed wires. * All guards must be in place. Repair or replace missing or damaged guards.* Disconnect any battery chargers that are not protected against the starter current drain. Check the condition and the electrolyte level of batteries, unless equipped with a maintenance free battery.* Inspect the engine-to-frame ground strap for good connection and condition.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 oil system.The engine must be on a level surface to properly perform this maintenance procedure.
Check Oil Level
1. Check the oil level with the engine stopped. Ensure that the engine when the oil level is not above the FULL RANGE zone on the dipstick.2. Maintain the oil level between the ADD and FULL marks on the ENGINE STOPPED side of the dipstick. Do not fill the crankcase above the mark in 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. The air bubbles created from the crankshaft dipping into the oil reduces the oil's lubricating characteristics and could 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 topic of this manual or consult your Caterpillar dealer before operating the engine.3. Remove the oil filler cap and add oil if necessary. See Refill Capacities and Lubricant Specifications for the size of your engine crankcase and recommended oil to use. Remote mounted or auxiliary oil filters require more oil than the Refill Capacities chart states. For all information pertaining to auxiliary oil filters, refer to the OEM or filter manufacturer's instructions.Cooling System
Make sure you read and understand the information in the Cooling System Specifications section of this manual before you proceed with maintenance of the cooling system.
Check Coolant Level
1. Check the coolant level with the engine stopped and cool.2. The filler cap covers the fill pipe. Remove the filler cap slowly to relieve any pressure.3. Maintain the coolant level within 13 mm (1/2 inch) below the bottom of the fill pipe or to the proper level on the sight glass (if equipped). 4. Inspect the filler cap. Replace the cap if gaskets are damaged. Install the filler cap.5. Inspect the radiator fins for dirt and debris and clean the fins if necessary.Clutch
Check/Adjust/Lubricate
Check/Adjust
New power take-offs should have clutch adjustment checked before being placed in service. Clutch adjustment should be checked again after the first ten hours of operation. New clutch plates have a "wear in" period, and the clutch may require several adjustments until the new plates are "worn in."
Clutch adjustment should be checked regularly after "wear in." Heavy duty applications which have frequent engagements and relatively long periods of clutch slip require more frequent adjustment than light duty applications. Operating torque should be measured to determine if clutch adjustment is required.Refer to the clutch OEM service instructions and the clutch instruction plate for adjustment and other service
