1. Turn adjusters in rocker arms or pivots down


(clockwise) only enough to capture push rods in


recesses.


2. Rotate crankshaft to establish TDC on compression


stroke for cylinder 1.


Check for:


a. Compression will be felt through spark plug hole.


b. Keyway of crankshaft will be aligned with cylinder


1.


c. No rocker arm/push rod movement if crankshaft


is rotated slightly back and forth. If they are


moving, rotate crankshaft 1 full revolution.


3. Insert a 0.127 mm (0.005 in.) feeler gauge between


end of 1 valve and rocker arm. Turn adjuster or


adjustment nut (based on design), until a slight drag


is felt. Hold in this position and tighten locking nut or


setscrew securely. Torque setscrew to 7.9 N·m


(70 in. lb.). After tightening recheck adjustment.


Proper valve clearance is 0.101/0.152 mm


(0.004/0.006 in.).


4. Repeat procedure for other valve on side 1.


5. Viewed from PTO end, rotate crankshaft 270° (3/4


turn) counterclockwise and align crankshaft keyway


with cylinder 2, which now puts cylinder at TDC on


compression stroke.


6. Repeat steps 3-4 for setting valve clearance on side


2.


7. Rotate crankshaft to check for free operation of


valve train. Check for clearance between valve


spring coils at full lift, or bending of push rod(s) can


occur. Minimum allowable clearance is 0.25 mm
