Valve Spring, Retainer and Seal: Removal

NOTE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.

1.

Remove the valve tappets from the cylinder being serviced. Refer to Valve Tappets .

2.

Rotate the crankshaft until the piston for the valve being serviced is at the top of its stroke.

NOTE: If a valve drops into the cylinder, remove the cylinder head. Refer to Cylinder Head - LH or Refer to Cylinder Head - RH .

NOTE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.

NOTE: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be removed, support the valve prior to removal or engine damage may occur.

3.
Pressurize the cylinder using compressed air.

4.

Using 303-300 T87C-6565-A, 303-350 T89P-6565-A and 303-1249, remove the keys, retainer and spring.
