Checking and Adjusting Valve Clearance
CAUTION: To prevent accidental starting of engine
while performing valve adjustments, always
disconnect NEGATIVE (—) battery terminal.
IMPORTANT: Valve clearance MUST BE checked
and adjusted with engine COLD.
1. Remove fuel injector heat shield, crankcase ventilator
tube, and rocker arm cover.
2. Remove plastic plug (A) from flywheel housing bores
and install appropriate flywheel turning tool JDG820,
or JDE83. Install JDG1571 or JDE81-4 flywheel timing
pin.
IMPORTANT: Visually inspect contact surfaces of
valve tips and rocker arm wear pads. Check all
parts for excessive wear, breakage, or cracks.
Replace parts that show visible damage.
Rocker arms that exhibit excessive valve
clearance should be inspected more thoroughly
to identify damaged parts.
3. Rotate engine in operating direction, with the flywheel
turning tool until locking pin engages timing hole in
flywheel.
