MAINTENANCE
EVERY 500 HOURS
INSPECTING AND CLEANING THE
SUPPLY PUMP STRAINER
• Do not smoke or permit open flames
while handling fuel or working on the
fuel system.
• Stop the engine in a well-ventilated
place and allow it to cool down before
performing maintenance.
• Clean up spilled fuel immediately.
• Before performing maintenance on top
of the work bench, clean the footing and
observe the following precautions to
prevent falling.
· Do not spill oil or grease.
· Do not leave tools scattered around.
· Watch your step when walking.
• Never jump down from the machine or
the work bench. When getting on or off
the machine or work bench, use the
steps, handrails or work bench to
support your body. Your weight should
be evenly distributed among the three
contact points (one hand and two feet
or two hands and one foot).
• Do not stand on the dozer blade and
perform maintenance work. Doing so is
dangerous because of the unsteady
foothold. Use the work bench.
1. Open the engine hood.
2. Place a pan under the joint bolt (1) to
catch fuel.
3. Loosen the joint bolt (1) and remove it.
4. Check the strainer (2) inside the joint bolt
(1), and clean it if it is dirty.
When cleaning, do not remove the strainer
(2) from the joint bolt. (Disassembly
prohibited)
If the dirt is persistent or the joint bolt is
clogged, replace the joint bolt with the
strainer in it.
5. Arrange the joint bolt (1), hose and the
new packing (3) together, and then install
them on their original positions.
· Joint bolt (1) tightening torque: 14.6 to
24.6 N·m (11 to 18 ft-lb)
6. Bleed air.
Refer to “Bleeding air from the fuel
system” on page 6-8.
Note: Replace the supply pump strainer
(integrated with the joint bolt), if the “lowered
output” or “engine stopping” cannot be
corrected after replacing the fuel filter
element. When replacing the strainer, replace
the packing on both sides of the hose with
the new one at the same time.
