Valve Lift Test
Remove the test cap from the feeder manifold and install the valve lift indicator (TOR4007). Make sure that the
dial indicator contacts the water valve.
Zero out the dial indicator.
Rotate the engine drive coupling and watch the dial indicator. The proper valve lift should be 0.090 to 0.102.
Valve lift too high.
Cause:
Water valve housing not correctly shimmed the cam housing.
Effect:
Water valve is open longer than necessary.
May leave slits between aeration holes.
Valve lift to low.
Water valve housing not correctly shimmed to the cam housing.
Worn cam lobe or valve roller.
Effect:
Short pulse duration does not release adequate water and hole depth can be affected.
Relief valve opens frequently, wasting energy.
Excessive clearance between cam and valve can cause stress on the valve.
