2. Apply a continuous bead of Genuine Liquid Gasket or equivalent
on the surface shown in the figure.
A: Apply bead so that it does not protrude into oil passage. Refer
to E M - 111 , "
Precautions For Liquid Gasket" .
B: Minimize the overlapping area of the bead, with start and end
areas of bead as shown in the figure.
Apply so that the portion marked * comes at an external loca-
tion but cannot be viewed externally after engine is assembled.
3. Install cylinder head assembly.
●Tighten bolts in numerical order as shown in the figure
according to the following procedure:
a. Apply engine oil to bolt threads and seat surfaces.
b. Tighten bolts to 29 to 38 N·m (2.9 to 3.9 kg-m, 21 to 28 ft-lb).
c. Tighten 180° to 185° [target: 180°] (angular tightening).
d. Loosen completely to 0 N·m (0 kg-m, 0 in-lb) in the reverse order
of that shown in the figure.
e. Tighten bolts to 35 to 44 N·m (3.5 to 4.5 kg-m, 26 to 32 ft-lb).
f. Tighten 90° to 95° [target: 90°] (angular tightening)
g. Tighten another 90° to 95° [target: 90°] (angular tightening).
●When an angle wrench is not used, paint an alignment
mark on the head of cylinder head bolt and cylinder head
surface before tightening. Check the angle with a protrac-
tor.
4. Install glow plug.
●To avoid damage, glow plugs should be removed only
when required.
●Handle with care to avoid applying shock. When dropped
from approx. 100 mm (3.94 in) or higher, always replace
with a new one.

WARNING:
●Situate vehicle on a flat and solid surface.
●Place chocks at front and back of rear wheels.
●For engines not equipped with engine slingers, attach proper slingers and bolts described in
PARTS CATALOG.
CAUTION:
●Always be careful to work safely, avoid forceful or uninstructed operations.
●Do not start working until exhaust system and engine coolant are cool enough.
●If items or work required are not covered by the engine main body section, refer to the applicable
sections.
●Always use the support point specified for lifting.
●Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for
unavoidable reasons, support at the rear axle jacking point with transmission jack or similar tool
before starting work, in preparation for the backward shift of center of gravity.
●For supporting points for lifting and jacking point at rear axle, refer to GI-35, "Garage Jack and
Safety Stand" .

INSPECTION AFTER INSTALLATION
●Before starting engine check the levels of engine coolant, lubrications and working engine oils. If less than
required quantity, fill to the specified level.
●Before starting engine, bleed air from fuel piping. Refer to FL-16, "Air Bleeding" .
●Run engine to check for unusual noise and vibration.
●Warm up engine thoroughly to make sure there is no leakage of engine coolant, lubricants, working
engine oil, fuel and exhaust gas.
●Bleed air from passages in pipes and tubes of applicable lines.

block.
●Install thrust bearings with oil groove facing to crankshaft arm
(outside).
c. Being careful with the direction, install main bearings.
●Install main bearings with the oil holes and grooves onto the
cylinder block side, and those without oil holes and grooves
onto the main cap side.
●While installing bearings, apply engine oil to bearing surfaces
(inside). Do not apply engine oil to rear surfaces, but clean
them completely.
