Cylinder Head Assembly Repair
NOTE:
Valve springs can be changed in two cylinders
at a time.
When the piston in cylinder one is at TDC, the piston
in cylinder six is also at TDC. When the piston in
cylinder two is at TDC, the piston in cylinder five is
also at TDC. When the piston in cylinder three is at
TDC, the piston in cylinder four is also at TDC.
If the rocker arm assembly was removed before TDC
was found, install the valve spring compressor and
compress the valve springs to open the valve. Turn
the crankshaft by hand in the normal direction until
the piston touches the valve. Continue to turn the
crankshaft and, at the same time, release the pres-
sure on the valve spring compressor until the piston
is at TDC. See Figure 11.

CYLINDER HEAD ASSEMBLY
Remove
1.
If the engine is still in the lift truck, do the fol-
lowing procedures:
a. Disconnect the battery terminals.
b. Drain the cooling system.
c.
Disconnect the sender unit for the coolant
temperature gauge.
2.
If equipped, remove closed circuit breather unit.
3.
Remove the Machine Interface Connector (MIC)
connection from the mounting bracket if the
mounting bracket is attached to the cylinder
head.
4.
Remove the air intake hose.
5.
Remove the fuel line between the cold start aid
in the induction manifold and the fuel filter. Dis-
connect the electrical connection and electrical
connectors from sensors.
6.
Disconnect all connections to the turbocharger
and remove turbocharger. See Turbocharger, Re-
move.
7.
Remove the induction manifold capscrews.
8.
Remove the induction manifold and gasket from
the cylinder head. Discard the gasket.
9.
Remove exhaust manifold fasteners and the ex-
haust manifold.
10. Remove the low pressure fuel lines between the
fuel injection pump and the fuel filter. Remove
the fuel filter bracket and the fuel filters.
11. Remove the high pressure fuel lines. Use a sep-
arate wrench to prevent movement of the outlets
of the fuel injection pump when the fuel lines are
disconnected. Put plugs in the open ports of the
fuel injection pump.
12. Remove the fuel injectors from the cylinder head.
Keep the fuel injectors clean and prevent damage
to the nozzles.
13. If an air compressor is installed, remove the
coolant pipe between the cylinder head and the
compressor. Remove the coolant pipe between
the bypass connection and the compressor.
