24.6.1 REPLACE ENGINE OIL FILTER

The lubricating oil filter is a spin-on type. This filter cannot be cleaned and should not be disturbed except when it is necessary to replace it.

Use only recommended filters available from your Komatsu distributor.

1. After reaching operating temperature, stop the engine and drain the crankcase oil. Refer to 24.6.2 CHANGING CRANKCASE OIL.

2. Clean the outside of the filter. Remove the spin-on type filter by turning it counterclockwise. Discard the old filter in a suitable, covered refuse container.

3. Fill the new filter element with clean engine oil and apply a little clean engine oil to the seal.

4. Thread the filter on by hand (do not spin) by turning it clockwise until the seal just makes contact the filter header. Give the element an additional 1/4 to 1/2 turn. Change the crankcase oil per step 24.6.2 following.

24.8.1 SERVICING THE DRIVE TRAIN SUCTION STRAINER

1. Remove the operators compartment floor board to locate the strainer.

2. Remove the four bolts (2) and separate the housing (6) from the base (1). Remove the element (4) with o-ring (5).

3. Wash the element and housing in a commercial solvent and dry thoroughly. Replace o-rings (3 and 5). Remove all dirt from the inside of the base using a cloth dampened with solvent.

4. Check that the new o-ring (5) is in place in the groove in the element (4). Slip the non o-ring end of the element into the housing. Secure the housing to the base (1) with the hardware previously removed.

5. Start the engine and let it idle for approximately five minutes. During this time, check the strainer for leaks. Correct all leaks no matter how minor. Then check the level in the drive train system. Reinstall the operators compartment floor board.

The primary element can be cleaned for a limited number of times before replacement is necessary, however, the safety element must be replaced when plugged. Detailed service procedures for this air cleaner are covered in the following text.

As a precaution against dirt entering the engine:

Make sure the air cleaner connections and the turbocharger mounting gaskets are in good condition and all joints and connections are tight.

Never operate the engine unless a filter element is in place and the filter end cover gasket is installed.

Never remove the element from the air cleaner while the engine is running.
