VALVES, VALVE SPRINGS AND VALVE SEALS INSTALLATION

Special Tools Required
- Valve Spring Compressor Attachment 07757-PJ1010A
- Commercially available Valve Spring Compressor KD383 No.32 jaws, commercially available
- Commercially available Valve Guide Seal Remover KD3372 commercially available

1. Coat the valve stems with engine oil. Install the valves in the valve guides.
2. Check that the valves move up and down smoothly.
3. Install the spring seats on the cylinder head.





4. Install the new valve seals (A) using the valve guide seal installer (B).

NOTE: Exhaust valve seals (C) have a black spring (A) and intake valve seals (E) have a white spring (F); they are not interchangeable.

5. Install the valve spring and valve retainer. Place the end of the valve spring with closely wound coils toward the cylinder head.





6. Install the valve spring compressor. Compress the spring and install the valve keepers.





7. Lightly tap the end of each valve stem two or three times with a plastic mallet (A) to ensure proper seating of the valve and valve keepers. Tap the valve stem only along its axis so you do not bend the stem.

CAMSHAFT/ROCKER ARMS, CAMSHAFT SEAL, AND PULLEY INSTALLATION
1. Apply a light coat of oil around the camshaft oil seal.
2. Gently tap the new camshaft oil seal (A) into the cylinder head.
-1 Tap the camshaft oil seal in squarely.
-2 Tap the oil seal into the cylinder head about 0.5-1.5 mm (0.02-0.06 inch) from the surface of the cylinder head.
3. Insert the camshaft (B) into the cylinder head, then install the camshaft thrust cover (C). Always use a new O-ring (D).





4. Check that the oil seal lips are not distorted.
5. Loosen the valve adjusting screws.
6. Set the rocker arm assembly in place and loosely install the bolts. Make sure that the rocker arms are properly positioned on the valve stems.





7. Tighten each bolt two turns at a time in the sequence shown to ensure that the rockers do not bind on the valves.





8. Install the injector base (A). Always use a new gasket (B).





9. Install the back cover (A), then install the camshaft pulley (B).
