   NOTICE
   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.

3. Apply clean engine oil to the gasket of the new oil filter.

   NOTICE
   Do not fill the oil filters with oil before installing them. This oil would not be filtered and could be contaminated. Contaminated oil can cause accelerated wear to engine components or engine damage.

4. Install the new engine oil filters by hand. Tighten each engine oil filter until the seal of each engine oil filter contacts the base of the oil filter housing. Note the position of the index marks on each filter in relation to a fixed point on the filter base.

   Note: Cat oil filters have rotation index marks spaced at 90 degrees or 1/4 of a turn. Use the rotation index marks as a guide when tightening the filters.

5. Tighten each filter according to the instructions that are printed on the filter. Use the index mark as a guide.

   Note: A Cat strap wrench or other suitable tool may be required to tighten the filters for final installation. Ensure that the installation tool does not damage the filters.

Inspect the Used Oil Filter Elements

1. Cut the used oil filter element open with a 4C-5084 Oil Filter Cutter. Spread apart the pleats and inspect the filter material for metal debris.

   An excessive amount of debris in the element may indicate premature wear or a pending failure.

2. Use a magnet to differentiate between the ferrous metals and the nonferrous metals that are found in the filter.

Ferrous metals may be from wear to the steel and the cast iron parts of the engine. Nonferrous metals may be from wear to 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.

Due to normal wear and friction, finding small amounts of debris in the oil filter is not uncommon. If an excessive amount of debris is found, consult your Cat dealer to arrange for further oil analysis.
