Rocker Arms
1.
Remove the valve cover.
2.
Mark or tag rocker arms in order of disassembly to keep
them in order for reassembly.
3.
Inspect the wear pad at the valve end of the rocker arm for
indications of scuffing or abnormal wear. If the pad is
grooved, replace the rocker arm.
NOTE: Do not attempt to true this surface by
grinding.
4.
Check the rocker arm pad and fulcrum seat for excessive
wear, cracks, nicks or burrs.
Push Rods
1.
Clean push rods (A) in a suitable solvent. Blow dry push
rods with compressed air.
2.
Use compressed air to confirm the oil passage is clear in the
center of the push rod.
3.
Check the ends of the push rods (A) for nicks, grooves,
roughness or excessive wear.
4.
The push rods (A) can be visually checked for straightness
while they are installed in the engine by rotating them with
the valve closed. Push rods can also be checked with a dial
indicator or rolled across a flat surface to check for
straightness.
5.
If the push rod (A) is visibly bent, it should be replaced.
Cylinder Head Removal
NOTE: The cargo box assembly and the upper frame
bolt-in brace must be removed to allow enough
clearance to remove all the cylinder head bolts.
Refer to Chapter 5 for removal procedures.
1.
Loosen the six cylinder head bolts evenly 1/8 turn each in
a criss-cross pattern until loose.
2.
Remove bolts (A) and tap cylinder head (B) lightly with a
soft face hammer until loose.
CAUTION:
Tap only in
reinforced areas or on thick parts of cylinder head casting
to avoid damaging the head or cylinder.
3.
Remove cylinder head (B) and head gasket (C) from the
cylinder (D).
WARNING
Always wear safety glasses when working with
compressed air to prevent personal injury.
