ENGINE
Valve Spring Setting Load
1. Place the valve spring on a tester and compress it to the same
length it is actually compressed in the engine.
2. Read the compression load on the gauge.
3. If the measurement is less than the allowable limit, replace it.

Oil Clearance between Rocker Arm Shaft and Bearing
1. Measure the rocker arm bearing I.D. with an inside micrometer.
2. Measure the rocker arm shaft O.D. with an outside micrometer,
and then calculate the oil clearance.
3. If the clearance exceeds the allowable limit, replace the rocker
arm and measure the oil clearance again. If it still exceeds the
allowable limit, replace also the rocker arm shaft.
W1063697
Oil Clearance between Valve Bridge Arm and Valve Bridge
Shaft
1. Measure the valve bridge arm (1) I.D. with an inside micrometer.
2. Measure the valve bridge shaft (2) O.D. with an outside
micrometer, and then calculate the oil clearance.
3. If the clearance exceeds the allowable limit, replace the valve
bridge arm (1) and measure the oil clearance again. If it still
exceeds the allowable limit, replace also the valve bridge shaft
(2).
