CAUTION:
Apply the liquid gasket around the bolt holes shown by the
arrows in the figure.
4) Install the gear case.
ITap the area around the dowel pin with a plastic hammer if it
cannot be inserted easily.
CAUTION:
Do not pop out the O-rings.
5) Install the holding bolt referring to the figure.
Dimension below neck:
A: 25 mm (0.98 in)
B: 30 mm (1.18 in)
C: 50 mm (1.97 in)
D: 80 mm (3.15 in)
E: 20 mm (0.79 in)
6) Install the holding bolts from the rear side of the front plate.
6. Install the crankshaft pulley.
IInsert by aligning the 2 sides of the oil pump with the 2 sides
of the shaft on the rear side of the crankshaft pulley.
CAUTION:
Do not damage the oil seal lip when inserting.
IRefer to EM-40, ªRemovalº for the crankshaft setting proce-
dures when tightening the holding nut.
7. Install the water pump.
IInstall it before installing the TDC sensor. Refer to ªWater
Pumpº in LC section.
8. Install the TDC sensor.
IAlign the bracket knock pin with the hole on the gear case side
and tighten the holding bolt.
IConfirm that the clearance between the end of the sensor and
the signal detection protrusion of the crankshaft pulley is within
the specification.
Standard: 1 0.8 mm (0.039 0.031 in)
IArrange the TDC sensor harness to the position shown in the
figure.
CAUTION:
Confirm that the harness has no deflection around the crank-
shaft pulley when installing the clamp.
9. Install the timing chain, other parts in connection with the tim-
ing chain, and the chain cover. Refer to EM-26, ªTIMING
CHAINº.

3) Install engine sub-attachment (SST) to the rear side of cylinder
block.
IAlign knock pin on cylinder block with pin hole on attachment
to install engine sub-attachment.
IMounting bolts are provided with engine sub-attachment.
4) Install engine attachment (SST).
IUse commercially available M12 mounting bolts and nuts (4
sets) with strength grade of 9T (minimum).
5) Hoist engine and install it to the engine stand (SST).
IEngine attachment and engine sub-attachment can be installed
to engine stand before engine installation.
4. Drain engine oil and coolant from engine.
5. Remove the following parts and related parts. (Only major parts
are listed.)
IAccessory belt
ICatalytic converter

Measurement of Compression Pressure
1. Warm up engine and switch off the ignition switch.
2. Remove glow plate and glow plugs.
3. Fit compression gauge adapter to cylinder head.
Compression gauge adapter:
:15-20N×m
(1.5 - 2.0 kg-m, 11 - 14 ft-lb)
4. Ensure the ignition switch is in the ªLOCKº position and discon-
nect harness connector (gray colored) from injection pump.
5. Crank engine, then read gauge indication.
IAlways use a fully-charged battery to obtain specified
engine revolution.
IEngine compression measurement should be made as
quickly as possible.
Compression pressure:
Unit: kPa (bar, kg/cm2, psi)/200 rpm
Standard 2,942 (29.4, 30, 427)
Minimum 2,452 (24.5, 25, 356)
Differential limit between cylinders 294 (2.9, 3, 43)
6. If cylinder compression in one or more cylinders is low, pour a
small amount of engine oil into cylinders through the glow holes
and retest compression.
IIf adding oil helps the compression pressure, piston rings
may be worn or damaged.
IIf pressure stays low, valve may be sticking or seating
incorrectly.
IIf cylinder compression in any two adjacent cylinders is
low, and if adding oil does not help the compression, there
is leakage past the gasket surface.
Leakage past the cylinder gasket can result in oil and water
becoming mixed in the engine block cooling and lubrica-
tion chambers.

Ð Connectors of the injection pump
5. Remove alternator adjusting bolt.
6. Disconnect exhaust manifold from front exhaust tube.
7. Remove turbocharger oil and water tubes.
8. Remove turbocharger bracket bolts.
9. Disconnect radiator outlet hose and thermostat housing water
inlet hose.
10. Remove fuel injection tube assembly and spill tube.
11. Remove injection nozzle holder from first cylinder with a spe-
cial tool (KV119E0030). Remove injection nozzles from cylin-
ders 2, 3 and 4 using a deep socket wrench.
12. Remove thermostat housing bolts shown at left.
