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
