CAUTION: CAUTION: Escaping fluid under
pressure can penetrate the skin causing
serious injury. Relieve pressure before
disconnecting fuel or other lines. Tighten all
connections before applying pressure. Keep
hands and body away from pinholes and
nozzles which eject fluids under high
pressure. Use a piece of cardboard or paper
to search for leaks. Do not use your hand.
If any fluid is injected into the skin, it must
be surgically removed within a few hours by
a doctor familiar with this type injury or
gangrene may result. Doctors unfamiliar with
this type of injury may call the Deere &
Company Medical Department in Moline,
Illinois, or other knowledgeable medical
source.
1. Thoroughly clean fuel filter assembly and
surrounding area.
2. Loosen drain plug (C) and drain fuel into a suitable
container.
NOTE: Lifting up on retaining ring as it is rotated helps
to get it past raised locators.
3. Firmly grasp the retaining ring (A) and rotate it
clockwise 1/4 turn. Remove ring with filter element
(B).
IMPORTANT: Do not dump the old fuel into the
new filter element. This could cause
fuel injection problem.
A plug is provided with the new
element for plugging the used
element.
4. Inspect filter mounting base for cleanliness. Clean
as required.
NOTE: Raised locators on fuel filter canister must be
indexed properly with slots in mounting base
for correct installation.
5. Install new filter element dry onto mounting base.
Be sure element is properly indexed and firmly
seated on base. It may be necessary to rotate filter
for correct alignment.
6. Install retaining ring onto mounting base making
certain dust seal is in place on filter base. Hand
tighten ring (about 1/3 turn) until it “snaps” into the
detent. DO NOT overtighten retaining ring.
NOTE: The proper installation is indicated when a
"click" is heard and a release of the retaining
ring is felt.
