SP10. INJECTORS
1. Fuel injectors should be checked by a Lugger-North-
ern Lights dealer or qualified fuel injection
shop every 600 hours.
2. Injector Removal:
You will need the following special tools:
JDE38A—Injection Nozzle Puller
JDE39—Nozzle Bore Cleaning Tool
JD258—Pilot Tool
a. Before removal, carefully remove all dirt from
the cylinder head around fuel injection nozzles.
Clean with compressed air to prevent dirt from
entering the cylinders or valve seats. Plug the
bore in the cylinder head after each fuel injection
nozzle has been removed. Cap fuel line openings
as soon as they are disconnected.
b. Immediately fit protective caps over the
nozzle tips and the line connections to avoid
handling damage.
c. Do not bend the fuel delivery lines. When
loosening the fuel pressure lines, hold male union
of nozzle line stationary with a backup wrench.
d. Loosen nuts to remove leak-off lines and T-fittings
and disconnect fuel injection line from nozzle.
NOTE: When all fuel injection nozzles have to be
removed, disconnect leak-off line assembly at fuel
tank, at injection pump, and at each nozzle T-fitting.
Lift off complete leak-off line as an assembly.
e. Remove cap screw, clamp and spacer.
f. Pull injection nozzle out of cylinder head with
JDE38A Injection Nozzle Puller.
NOTE:
Do not use screwdrivers, pry bars, or similar
tools for this as they might damage the injection nozzle.
3. Clean Injector Bore:
Always turn the tool clockwise through the bore
even when removing from bore, otherwise tool
may become dull.
a. Clean nozzle bore with JDE39 Nozzle Bore
Cleaning Tool. Blow debris from bore with
compressed air and plug the bore to prevent entry
of foreign material.
4. Clean injection nozzles:
a. Remove carbon stop seal
(Figure 12-A)
and upper
sealing washer
(Figure 12-B)
, using a needle-nose
pliers. Discard seals.
b. Clean exterior of nozzle by soaking in clean
solvent or diesel fuel. Clean tip with brass wire
brush.

the nozzle body above the carbon stop seal groove.
This coating will become discolored during normal
operation, but this is not harmful. Do not use a motor
driven brush to clean up nozzle body.

5. Install seals on injection nozzle.
NOTE:
Each time an injection nozzle is removed
from the cylinder head, replace carbon stop seal (B)
with a new one.
a. Position JD258 (ROS16477) Pilot Tool
(Figure
13-C)
over nozzle tip. If Pilot Tool (included in
cleaning kit) is not available, use a No. 16189
Nozzle Protector Cap found on every new or
re-placement nozzle.
b. Position a new carbon stop seal
(Figure 13-B)
on
pilot tool. Use a new seal washer
(Figure 13-A)
to
help slide the carbon seal into place until it seats
in its groove on nozzle body.
c. Continue to slide upper sealing washer onto
nozzle body until it seats against inlet fitting.
