Tools Required

1. Remove the valve rocker arm cover. Refer to Valve Rocker Arm Cover Replacement .
2. Remove the required valve rocker arms. Refer to Valve Rocker Arm and Push Rod Removal .
3. Remove the required spark plugs. Refer to Spark Plug Replacement in Engine Electrical.
4. Install the J 22794 into the spark plug hole.
5. Connect a shop air supply hose and apply compressed air in order to hold the valves in place.



6. Remove a bolt from a valve rocker arm.
7. Install a flat washer on the bolt.
8. Install the bolt in the valve rocker arm bolt hole for the valve spring requiring removal.

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.

9. Use the J 5892-D in order to compress the valve spring.

9.1.	Hook the slotted end of J 5892-D under the washer on the valve rocker arm bolt.

9.2.	Apply steady pressure on the valve spring cap until the valve keys are accessible.





Notice: Completely engage the J 38606 jaws on the valve spring. The J 38606 may slip off and scratch the valve spring. Replace the valve spring if the valve spring becomes scratch.

10. Use J 38606 when J 5892-D will not fit.



11. Remove the valve keys (1).
12. Carefully release the valve spring tension.
13. Remove the J 5892-D or J 38606 .
14. Remove the valve spring cap (2) and valve spring (3).
15. Remove the valve stem oil seal (4).

1. Install the valve seals (4). Refer to Cylinder Head Assemble .
2. Install the valve spring (3).
3. Install the valve spring cap (2) on the valve stem.

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.

4. To press the valve spring (3) use the J 5892-D .




Notice: Completely engage the J 38606 jaws on the valve spring. The J 38606 may slip off and scratch the valve spring. Replace the valve spring if the valve spring becomes scratch.

5. Use theJ 38606 if the clearance does not permit use of the J 5892-D .
6. Install the valve stem keys.

Use grease in order to hold the valve stem keys in place.




7. Carefully release the valve spring pressure, making sure the valve stem keys stay in place.

Notice: The valve stem keys must correctly seat in the valve spring cap. Engine damage may occur by not installing properly.

8. Remove the J 5892-D or the J 38606 .

8.1.	Look to ensure that the valve stem keys seat properly in the upper groove of the valve stem.

8.2.	Tap the end of the valve stem with a plastic faced hammer in to seat the valve stem keys, if necessary.
