b. Disassembly
1. Remove five capscrews, fuel level sender (2,
Fig. 8.18) and gasket from fuel tank.
2. Remove fuel supply and return elbows (4 and
20) and rubber bushings (19) from fuel tank.
c. Cleaning and Drying
If contaminated fuel or foreign material is in the
tank, the tank can usually be cleaned. Replace
tank if tank is damaged or if there are leaks in
unreparable areas.
Clean the tank as follows:
1. Have a dry chemical (Class B) fire extin-
guisher near the work area.
2. Disconnect the negative (–) battery cable.
3. Remove and disassemble fuel tank as de-
scribed in paragraphs a and b. Invert, rock
and drain tank.
4. Clean tank with high pressure washer or flush
with hot water for five minutes. Invert, rock
and drain tank completely.
5. If necessary, add a diesel fuel emulsifying
agent to the tank, refill with water, and agitate
mixture for 10 minutes. Drain tank completely.
Refer to manufacturer's instructions for correct
emulsifying agent to water mixture.
6. When empty, refill to overflowing with water.
Completely flush and empty tank.
d. Inspection and Replacement
1. Plug all outlets before removing a fuel tank for
a suspected fuel leak; make sure that one of
the fuel hoses isn't leaking onto the tank.
2. To test a fuel tank which is out of the forklift,
plug all openings except a supply or return
elbow. Apply a small amount of air pressure
to tank through this elbow (approximately 1 to
1-1/2 psi (0,07 to 0,10 bar). Test tank for
leaks by applying soap solution to exterior of
tank or by submerging tank in water and
looking for bubbles.
This procedure will not remove all fuel vapor.
Do not attempt any repair on tank where heat
or flame is required, as an explosion resulting
in personal injury could occur.
3. For a short term repair you may be able to
repair a small leak by installing a sheet metal
screw with a neoprene gasket in the opening.
Replace tank for long term repair.
e. Assembly
1. Install rubber bushings (19, Fig. 8.18) and fuel
supply and return elbows (4 and 20) in tank.
2. Position fuel level sender gasket and fuel level
sender (2) in tank.
3. Loosely install the screw which secures the
ground wire to the sender and fuel tank.
4. Install the other four screws and alternately
torque the five screws which secure the
sender to the fuel tank from 10 to 14 lb-inch
(1,13 to 1,58 N m). Use No. 10-24 screws.
5. Install the wire and nut on the center terminal
of the sender.
