2. Remove fuel ®lter using band-type ®lter wrench.
Remove fuel ®lter and fuel ®lter sensor.
CAUTION:
Remove fuel ®lter without spilling fuel. If spilt, wipe off imme-
diately. Be specially careful not to spill fuel on engine mount
insulator.
3. Wipe clean fuel ®lter mounting surface on fuel ®lter bracket and
smear a little fuel on rubber seal of fuel ®lter.
4. Screw fuel ®lter on until a slight resistance is felt, then tighten
an additional more than 2/3 of a turn.
5. Install fuel ®lter sensor to new fuel ®lter.
6. Bleed air from fuel line.
Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively.
If water does not drain properly, move the priming pump up and
down.
2. Bleed air.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.

Cleaning and Replacing Air Cleaner Filter
VISCOUS PAPER TYPE
The viscous paper type air cleaner ®lter does not require any clean-
ing operation between renewal.
Checking Injection Nozzle
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to come into contact with your hand or
body, and make sure that your eyes are properly protected.
1. Install nozzle to injection nozzle tester and bleed air from ¯are
nut.
2. Check initial injection pressure by pumping tester handle one
full stroke per second.
Initial injection pressure:
Used nozzle
More than 14,220 kPa
(142.2 bar, 145 kg/cm
2, 2,062 psi)
New nozzle
14,711 - 15,495 kPa
(147.1 - 155.0 bar, 150 - 158 kg/cm
2,
2,133 - 2,247 psi)
+Always check initial injection pressure before installing
new nozzle.
3. Check spray pattern by pumping tester handle one full stroke
per second.
a. If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates from
main spray (pattern B).
4. If initial injection pressure or injection nozzle is not normal,
adjust or clean injection nozzle.
5. Test again. If it is not corrected, replace nozzle.
Refer to EC section for injection pressure adjustment, clean-
ing and replacement.

6. Install all injection nozzles with Tool and securely connect fuel
spill tube and delivery tubes.
7. Bleed air from fuel system and check for fuel leakage with
engine running.

:59-69Nzm (6.0 - 7.0 kg-m, 43 - 51 ft-lb)
Spill tube nut:
:39-49Nzm (4.0 - 5.0 kg-m, 29 - 36 ft-lb)
Injection tube:
:20-25Nzm (2.2 - 2.5 kg-m, 16 - 18 ft-lb)
Checking Idle Speed
Inspection should be carried out with gears in ``Neutral'' and
with air conditioner and other electrical loads off.
1. Warm up engine until engine coolant temperature indicator
points to the middle of gauge.
2. Attach a diesel tachotester's pick-up to No. 1 fuel injection tube.
3. Race engine two or three times and check idle speed.
