5 - 36
Contact your authorized dealer to check the
valve clearance.
Normal clearance:
Intake: 0.15mm (0.0059 in)
Exhaust: 0.25mm (0.0098 in)
If the gap is large, the valves can make a loud
tapping noise and if the gap is too small, the
engine output power may be reduced due to
leakage of compressed air.
(2) Checking Nozzle injection pressure
Contact your authorized local dealer for check.
Nozzle injection pressure: 12.3~13.3 MPa (1784~1929 psi)
▶
Only qualified service personnel should perform this maintenance. Contact your
authorized local dealer for this maintenance. Operation of engines with incorrect
valve lash can reduce engine efficiency, and also reduce engine component life.
Caution
▶
Ensure that the engine can not be started while this maintenance is being
performed. To help prevent possible injury, do not use the starting motor to turn the
flywheel.
▶
Hot engine components can cause burns. Allow additional time for the engine to
cool before measuring/adjusting valve lash clearance.
Warning
▶
Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel
system component that will be disconnected. Fit a suitable cover over disconnected
fuel system component.
▶
If a fuel injector is suspected of operating outside of normal parameters, it should
be removed by a qualified technician. The suspect fuel injector should be taken to
an authorized agent for inspection.
Caution
▶
Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire.
▶
Work carefully around an engine that is running. Engine parts that are hot, or parts
that are moving, can cause personal injury.
▶
Make sure that you wear eye protection at all times during testing. When fuel
injection nozzles are tested, the high pressure test fluid can pierce the skin and
cause serious injury to the operator. Always keep the tip of the fuel injection nozzle
pointed away from the operator and into the fuel collector and extension.
