4. Wipe clean fuel filter mounting surface on fuel filter bracket andsmear a little fuel on rubber seal of fuel filter.
5. Screw fuel filter on until a slight resistance is felt, then tighten an additional more than 2/3 or a turn.
6. Install fuel filter sensor to new fuel filter. (Type A)
7. Bleed air from fuel filter.
Refer to ªAir Bleedingº in EC section.
8. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Type A
Loosen drain cock and drain water.
Loosening drain cock four to five turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
If water does not drain properly, move the priming pump up and
down.
Type B
Loosen air bleeder screw from the sedimentor cover and then
loosen drain cock and drain water.
Loosening drain cock four to five turns causes water to start
draining. Do not remove drain cock by loosening it exces-
sively.
2. Bleed air.
Refer to ªAir Bleedingº in EC section.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.

2. Move the following parts.
ITDC sensor harness
I Power steering oil pump
3. Remove the chain cover.
I Remove the holding bolts A to C shown in the figure.
CAUTION:
While the chain cover is removed, be careful not to allow entry
of dust or foreign objects.
4. Set the No. 1 cylinder to the TDC.
1) Turn the crankshaft pulley clockwise, and match the timing indicator of the gear case to the timing mark of the crankshaft
pulley.
2) Make sure that the cam sprocket match mark is in the position shown in the figure.
I If the match mark is not in position, turn the crankshaft pulley
once more and position it.
I When removing at No. 1 cylinder TDC, each sprocket and chain
is fitted using the match mark, therefore there is no need to
apply any match marks beforehand.
5. Remove the chain tensioner.
1) Loosen upper and lower holding bolts.
2) Holding the chain tensioner in your hand, remove the upper holding bolt and release the spring tension.
3) Remove the lower holding bolt, then remove the chain ten- sioner.
I The chain tensioner does not have a mechanism which pre-
vents the ejection of the plunger. (It does have a mechanism
which prevents the plunger from returning.)
CAUTION:
Be careful not to drop the plunger and spring.

depending on the part.
Dimension below the neck: A: 20 mm (0.79 in)
B: 50 mm (1.97 in)
C: 60 mm (2.36 in)
6. Install by following all removal procedures in reverse.
CAUTION:
I Arrange the TDC sensor harness in the position shown in
the figure.
I Make sure that the harness has no deflection around the
vicinity of the crankshaft pulley when installing the clamp.

Inspection
IWhen the camshaft or parts in connection with valves are
removed or replaced, and a fault has occurred (poor starting,
idling, or other faults) due to the misadjustment of the valve
clearance, inspect as follows.
I Inspect and adjust when the engine is cool (at normal tempera-
ture).
I Be careful of the intake and exhaust valve arrangement. (The
valve arrangement is different from that in a normal engine.)
(The camshafts have, alternately, either an intake valve or an
exhaust valve.)
1. Remove the following parts.
I Intercooler cover
I Intercooler
I Rocker cover
2. Set the No. 1 cylinder at TDC.
1) Rotate the crankshaft pulley clockwise, and align the TDC mark of the crankshaft pulley with the timing indicator of the TDC
sensor bracket.
2) Confirm that the cam nose of the No. 1 cylinder and the knock pin of the cam sprocket is in the position shown in the figure.
I Rotate the crankshaft pulley again if not in the position shown
in the figure.
3. While referring to the figure, measure the valve clearance in the circled area of the table below.

The injection order is 1-3-4-2.
I Measure the valve clearance using a JIS high grade feeler
gauge when the engine is cool (at normal temperature).
Standard: Intake and exhaust0.35 0.05 mm (0.0138 0.0020 in)
4. Set the No. 4 cylinder at TDC by rotating the crankshaft clock- wise once.

Removal
1. Remove the engine assembly.Refer to ªENGINE REMOVALº, EM-63.
2. Place the engine on an engine stand (SST). Refer to ªCYLINDER BLOCKº, EM-67.
3. Remove the following.
I Auto tensioner bracket
I Air conditioner bracket
I Alternator bracket
I Oil tube
I Vacuum pump
I Rocker cover
I Oil pan (upper, lower)
I Injection tube
I Spill tube
I High pressure nozzle assembly
4. Remove the chain cover, timing chain and other parts in con- nection.
Before removing timing chain, remove injection pump sprocket
with No. 1 cylinder being positioned at TDC. Refer to the fig-
ure. Refer to ªTIMING CHAINº, EM-26.
CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
I Do not paint the match mark on the timing chain beforehand as
the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
I Do not drop or hit the sensor.
I Store in a clean place free of iron filings, etc.
I Do not place near any magnetic equipment.
6. Remove the water pump. Refer to ªWATER PUMPº in LC section.

CAUTION:
Do not damage the oil seal lip when inserting.
I Refer to EM-40, ªRemovalº for the crankshaft setting proce-
dures when tightening the holding nut.

the signal detection protrusion of the crankshaft pulley is within
the specification.
Standard: 1 0.8 mm (0.039 0.031 in)
I Arrange the TDC sensor harness to the position shown in the
figure.
CAUTION:
Confirm that the harness has no deflection around the crank-
