Timing Cover: Service and Repair

Cylinder Front Cover

Removal

1. Drain the cooling system.

2. Remove the shroud and radiator.

3. Remove the drive belt, power steering pump, air conditioning compressor and power steering/air conditioning bracket.

4. Remove the screw and washer from the end of the crankshaft and remove the damper using Crankshaft Damper Remover T58P-6316-D.






5. Remove the front oil pan and front cover attaching screws. Loosen the first six bolts on each side of the pan. Lightly push pan down so it does not exert any upward force on the front cover, which may affect front seal alignment.

6. Remove the cylinder front cover and discard the gasket. Replace crankshaft oil seal whenever the cylinder front cover is removed.

Installation

1. Clean front cover and block gasket surfaces. Also, clean any oil on oil pan gasket as it will be re-installed.

2. Coat front cover gasket surfaces of the block and cover with Perfect Seal Sealing Compound B5A-19554-A (ESR-M18P2-A) or equivalent oil resistant sealer. Position a new front cover gasket on the block.

3. Apply Silicone Rubber D6AZ-19562-AA or BA (ESB-M4G92-A) or equivalent to the block/pan junction and a small bead on oil pan gasket sealing surface of front cover. This provides an additional seal between front cover and the used oil pan gasket.

NOTE: When applying RTV sealant, always use the bead size specified and join the components within 15 minutes of application. After this amount of time the sealant begins to set up and its sealing effectiveness may be reduced.






4. Position the front cover assembly over the end of the crankshaft and against the cylinder block. Start the cover and pan attaching screws. Slide the Front Cover Aligner T61P-6019-B or equivalent over the crank stub and into the seal bore of the cover. Tighten attaching oil pan screws to 14-20 Nm (10-15 ft.lb) and front cover screws to 17-24 Nm (12-18 ft.lb).

Note:Tighten front cover screws first to obtain proper cover alignment.






5. Lubricate the crank stub, damper hub inside diameter and the seal rubbing surface with clean engine oil or 50 weight oil only. Do not use grease on seal. Apply a 6 mm (1/4 inch) bead of silicone rubber to inside of keyway of damper hub. Align the damper keyway with the key on the crankshaft and install the damper using Crankshaft Sprocket and Damper Replacer T52L-6306-AEE.






6. Install the washer and capscrew.

7. Install the power steering pump, air conditioning compressor, power steering/air conditioning bracket and drive belt.

8. Install the shroud, radiator, and hoses.

9. Fill and bleed the cooling system. Use the specified antifreeze mix. If foreign material has not entered the crankcase during the service work, it is not necessary to change the engine oil.

10. Change the engine oil with proper quantity and quality oil.

CAUTION: To avoid damage to the engine due to entrance of foreign material during repairs, engine oil must be changed when repairs are completed.

11. Operate the engine at fast idle and check for coolant and oil leaks.
