24. SERVICE PROCEDURE 24.6 EVERY 1000 HOURS SERVICE Carry out maintenance for EVERY 250 HOURS and EVERY 500 HOURS SERVICE at the same time. 24.6.1 REPLACE CORROSION RESISTOR CARTRIDGE WARNING The oil is at high temperature after the engine has been oper- ated, so never replace the cartridge immediately after finishing operations. Wait for the oil to cool down before replacing the cartridge. Prepare a filter wrench and a container to catch the water. 1. Screw in valve 1 (2 places) at the top of the corrosion resistor. 2. Set the container to catch the water under the cartridge. 3. Using a filter wrench, remove cartridge 2 . 4.
Clean the filter holder, coat the seal surface of the new cartridge thinly with engine oil, then install the cartridge. AE616560 5. When installing, tighten until the gasket contacts the seal surface of the filter holder, then tighten a further 2/3 turns. If the filter cartridge is tightened too far, the gasket will be damaged and this will lead to leakage of water. If the filter is too loose, water will also leak from the gap at the gasket, so always tighten the correct amount. 6. Open valve 1 (2 places). 7. After replacing the cartridge, start the engine and check that there is no leakage of water from the filter seal surface.
If there is any leakage of water, check the tightening of the filter car- tridge. 3-64
