5-3 Engine Maintenance
Rev. “C”
~ 5-3-29 ~
5-3.34.2 Replace the Oil Filter
Remove the oil fi lter with a 185-3630 Chain Wrench.
Cut the oil fi lter open with a 175-7546 Oil Filter Cutter. Break apart the pleats and inspect the oil fi lter for metal debris.
An excessive amount of metal debris in the oil fi lter may indicate early wear or a pending failure.
1.
2.
Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are
found in the oil fi lter element. Ferrous metals may indicate wear on the steel and cast iron parts
of the engine.
Nonferrous metals may indicate wear on the aluminum parts, brass parts or bronze parts of
the engine. Parts that may be affected include the following items: main bearings, rod bearings,
turbocharger bearings, and cylinder heads.
Due to normal wear and friction, it is not uncommon to fi nd small amounts of debris in the oil
fi lter. Consult your Caterpillar dealer in order to arrange for a further analysis if an excessive
amount of debris is found in the oil fi lter.
Clean the sealing surface of the fi lter mounting base. Ensure that all of the oil fi lter gasket is removed.
Apply clean engine oil to the new oil fi lter gasket.
3.
4.
Install the new oil fi lter. Tighten the oil fi lter until the oil fi lter gasket contacts the base. Tighten the oil fi lter by hand
according to the instructions that are shown on the oil fi lter. Do not over tighten the oil fi lter.
5.
5-3.34.3 Fill the Engine Crankcase
Remove the oil fi ller cap. Refer to “
Lubricant Specifi cations
” section of this manual for more information. Fill the
crankcase with the proper amount of engine oil. Refer to “
Refi ll Capacities
” section of this manual for more information.
1.
Start the engine and run the engine at “LOW IDLE” for two minutes. Perform this procedure in order to ensure that the
lubrication system has oil and that the oil fi lters are fi lled. Inspect the oil fi lter for oil leaks.
Stop the engine and allow the oil to drain back to the sump for a minimum of ten minutes.
Remove the oil level gauge in order to check the oil level. Maintain the oil level between the “ADD” and “FULL” marks on
the oil level gauge.

3.
NOTICE:
To help prevent crankshaft or bearing damage, crank engine to fi ll all fi lters before starting. Do not
crank engine for more than 30 seconds.
NOTICE:
If equipped with an auxiliary oil fi lter or system, extra oil must be added when fi lling the crankcase.
Follow the OEM or fi lter manufacturer’s recommendations. If the extra oil is not added, the engine may starve for oil.
NOTICE:
Do not fi ll the oil fi lters with oil before installing them. This oil would not be fi ltered and could be
contaminated. Contaminated oil can cause accelerated wear to engine components.
NOTICE:
Caterpillar oil fi lters are built to Caterpillar specifi cations. Use of an oil fi lter not recommended by
Caterpillar could result in severe engine damage to the engine bearings, crankshaft, etc., as a result of the larger
waste particles from unfi ltered oil entering the engine lubricating system. Only use oil fi lters recommended by
Caterpillar.
