Tools Required

EN-47945 Valve Spring Compressor

1. Remove the camshaft cover . Refer to Camshaft Cover Replacement .
2. Rotate the crankshaft until the affected cylinder valve is fully open (cam lobe fully depressing the spring).

Important: Engine design and packaging does not allow all cylinder locations to use both fasteners for holding the tool to the cylinder head. One fastener is sufficient in these locations.




3. Install the EN-47945 on the engine cylinder head using either one or two of the supplied fasteners installed in the coil fastener hole.

Important: DO NOT rotate the engine with the tool installed. It is possible to damage the valves if they contact the piston. Rotate the engine enough to come back to the base circle of the cam.

4. Rotate the engine clockwise enough to ensure the cam is on the base circle (spring will stay compressed by the tool).

This will allow the lash adjuster and rocker to be removed.

5. Remove the valve rocker arm and valve lash adjuster.
6. Clean and inspect the valve rocker arm and valve lash adjuster. Refer to Valve Rocker Arm and Valve Lash Adjuster Cleaning and Inspection .

1. Lubricate the valve rocker arm and fill the valve lash adjuster with oil.
2. Install the valve rocker arm and valve lash adjuster.
3. When the valve rocker arm and valve lash adjuster are in place, slowly rotate the engine counterclockwise enough that the cam lobe fully depresses the spring again.



4. Remove the EN-47945 from the cylinder head and repeat as required.
5. Install the camshaft cover. Refer to Camshaft Cover Replacement .
