Removal and Installation
REMOVE FUEL INJECTION NOZZLES
CAUTION: Escaping diesel fuel under pressure
can have sufficient force to penetrate the skin,
causing serious injury. Before disconnecting
lines, be sure to relieve pressure. Before
applying pressure to the system, be sure ALL
connections are tight and lines, pipes, and
hoses are not damaged. Keep hands and body
away from pin holes and nozzles which eject
fluid under pressure. Use a piece of cardboard
or wood, rather than hands, to search for
suspected leaks.
If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a
04
0400
doctor familiar with this type injury or gangrene
28
may result. Doctors unfamiliar with this type of
injury may call Deere & Company Medical
Department in Moline, Illinois, or other
knowledgeable medical source.
IMPORTANT: Cap or plug all fuel lines as they are
disconnected to prevent dirt and debris
from entering fuel system. Debris in fuel
system can plug injectors which affects
A--Injection Line Nut
engine performance.
B--JDE90 Serrated Wrench
C--JDF22 Crowsfoot Wrench
1. Thoroughly clean area around injection pump and
nozzles, including all line connections, using
compressed air.
IMPORTANT: JDE90 Serrated Wrench (B) MUST BE
used to keep delivery valve fittings
stationary while loosening line nuts. If
delivery valve and barrel housing
rotates while loosening or tightening a
fuel line nut, injection pump delivery
will be altered. Pump must be
recalibrated on a test stand.
2. Disconnect injection line nuts (A) from injection pump
delivery valves using JDF22 Crowsfoot Wrench (C) or
a standard 3/4 in. line wrench and JDE90 Serrated
Wrench (B).
