EXHAUST-VALVE CLEARANCE ADJUSTMENT
between the end of one valve stem and the rocker arm bridge but the 0.027inch gage will not pass through.
Readjust the push rod, if necessary.
Adjust and check the remaining exhaust valves in the same manner as above.
Valve Clearance Adjustment (Hot Engine)
Maintaining normal engine operating temperature is particularly important when making the final exhaust valve
clearance adjustment. If the engine is allowed to cool before setting any of the valves, the clearance, when
running at full load, may become insufficient.
With the engine at normal operating temperature (refer to Engine Operating Conditions
Specifications), recheck the exhaust-valve clearance with feeler gage J 9708-01. At this time, if the valve
clearance is correct, the 0.023-inch gage will pass freely between the end of one valve stem and the rocker arm
bridge but the 0.025-inch feeler gage will not pass through. Readjust the push rod, if necessary.
After the exhaust-valve clearance has been adjusted, check the fuel injector timing (Fuel Injector
Check Exhaust-Valve Clearance Adjustment
With the engine operating at 100 (38 ) or less, check the valve clearance.
If a 0.026-inch feeler gage (J 9708-01) 0.006 inch will pass between the valve stem and the rocker
arm bridge, the valve clearance is satisfactory. If necessary adjust the push rod.
