Caterpillar oil filters are built to Caterpillar specifications. Use of an oil filter 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 unfiltered oil entering the engine lubricating system. Only use oil filters recommended by Caterpillar. |
- Check the oil level according to the instructions in this Operation and Maintenance Manual, "Engine Oil Level - Check".
Inspect the Used Oil Filter Elements
Cut the used oil filter element open with a Cat filter cutting tool.
Remove the metal wrap. Cut the filter element free from the end caps. Spread apart the pleats and inspect the element for metal debris. Due to normal wear and friction, Small amounts of debris may be found in the oil filter element. An excessive amount of debris in the element may indicate early wear or a pending failure. If an excessive amount of debris is found in the oil filter element, consult your Cat dealer in order to arrange for further oil analysis.
Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the element. Ferrous metals may indicate wear on the steel and the cast iron parts of the engine. Nonferrous metals may indicate wear on the aluminum parts, the brass parts, or the bronze parts of the engine. Parts that may be affected include the following components: main bearings, rod bearings, turbocharger bearings and cylinder heads.
