Tools Required

1. Using an appropriately sized deep socket and a plastic hammer, lightly tap on the valve spring retainer to loosen the valve keepers.




Caution: Compressed valve springs have high tension against the valve spring compressor. Valve springs that are not properly compressed by or released from the valve spring compressor can be ejected from the valve spring compressor with intense force. Use care when compressing or releasing the valve spring with the valve spring compressor and when removing or installing the valve stem keys. Failing to use care may cause personal injury.

Notice: Do not compress the valve springs to less than 24.0 mm (0.943 in). Contact between the valve spring retainer and the valve stem oil seal can cause potential valve stem oil seal damage.

2. Compress the valve spring using the J 8062 and the J 42037 .



3. Use the magnetic end of the J 43059 in order to remove the valve keepers.
4. Remove the valve spring compressor and the pilot.



5. Remove the valve spring retainer (2).



6. Remove the valve spring.




Important: NEVER reuse a valve stem oil seal.

7. Remove the valve stem oil seal using the J 38820 and discard.



8. Remove the valve (1).
9. Repeat these procedures for the remaining valves.
