Maintenance: Fuel System

Install the nozzle

1. Install the nozzle according to the pin on the

nozzle.

2. Tighten the retaining nut by applying the specified

torque 177 to 196 Nm (18 to 20kpm) [130 to 145
lbf.ft]. (Apply oil to the nut.)

IMPORTANT!

Do not use Moly Disulfide.

3. Adjust the nozzle opening pressure and check

spray conditions.

Fuel injection pressure

WARNING!

Do not allow the fuel injected from a

nozzle to contact the skin or body when
inspecting the nozzle using a nozzle tester. The
fuel injected from the nozzle has an extremely
high pressure, strong enough to penetrate skin
and causing serious injury.

1. Attach the fuel injector to the nozzle tester.

2. While watching the pressure gage of the nozzle

tester, push the handle down slowly.

IMPORTANT!

If fuel drips from the end of

the nozzle tip it must be replaced.

3. When the handle is being pressed down, the fuel

is injected, and the pressure on the pressure
gage drops suddenly. The pressure value indica-
ted at this point is the fuel injection start pressure.

4. Close the valve on the injection pump. If the pres-

sure on the gage drops too fast ( most probably
due to lekage) the nozzle must be replaced.

NOTE!

Make sure it isn’t the injection pump itself that

is leaking.

Nozzle opening pressure

34.32 MPa (350 kp/cm

) [4979 psi]
