NOTE
Cylinder head need not be removed to carry out this task. The following REMOVAL instructions assume
cylinder head is not removed.
REMOVAL
(1)
Tag and remove the fuel pipes from the injector and fuel connectors.
NOTE
Immediately after removing the fuel pipes, cover the injector fuel inlet and outlet openings with shipping
caps to prevent dirt or foreign material from entering.
(2)
Turn the crankshaft with J22582, or crank the engine with starting motor, to bring the injector and valve
rocker arms in line horizontally.
NOTE
Do not bar the crankshaft in a left-hand direction of rotation with a wrench or barring tool on the crankshaft
bolt, because the bolt may loosen.
(3)
Remove the two bolts which secure the rocker arm shaft brackets to the cylinder head. Remove the
brackets and shaft.
NOTE
When removing the rocker arm shaft, fold the three rocker arms back just far enough so the shaft can be
removed. Do not force the rocker arms all the way back with the shaft in place as this may impose a load
that could bend the push rods.
