INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter

Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.

If reduction of outer diameter appears in a position other than
“d2”, use it as “d2” point.
NOTE:
When replacing any cylinder head bolts, it is possible to use them
with mixing flange bolt and bolt with washer.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checked. Refer to EM-110, "
CYLIN-
DER BLOCK DISTORTION" .
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.

If it exceeds the limit, replace cylinder head.Bolt with washer

2. Tighten cylinder head bolts in numerical order as shown in figure
with the following procedure, and install cylinder head.
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Refer to EM-72, "
Cylinder Head
Bolts Outer Diameter" .
a. Apply new engine oil to threads and seating surface of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 60 degrees clockwise (angle tightening).
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order of that indicated in the figure.
e. Tighten all bolts.
f. Turn all bolts 75 degrees clockwise (angle tightening).
g. Turn all bolts 75 degrees clockwise again (angle tightening).
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judgment
by visual inspection without the tool.
3. Install in the reverse order of removal after this step.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-17, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.

Bleed air from lines and hoses of applicable lines, such as in cooling system.

After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary. : 50 N·m (5.1 kg-m, 37 ft-lb)

Main bearing with an oil hole and groove goes on cylinder
block. The one without them goes on lower cylinder block.

Only main bearing (on cylinder block) for No. 3 journal has dif-
ferent specifications.

Before installing main bearings, apply new engine oil to the
bearing surface (inside). Do not apply new engine oil to the
back surface, but thoroughly clean it.

When installing, align main bearing stopper to the notch.

Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
4. Install signal plate to crankshaft if removed.
a. Position crankshaft and signal plate using a dowel pin, and
tighten mounting bolts.
b. Remove dowel pin.
CAUTION:
Be sure to remove dowel pin.
NOTE:
Dowel pin of crankshaft and signal plate is provided as a set for
each. If dowel pin is not available (when reusing crankshaft and
signal), use M6 bolt [length 10 mm (0.39 in) or more] as a substi-
tute.
5. Install crankshaft to cylinder block.

While turning crankshaft by hand, make sure that it turns smoothly.
6. Install lower cylinder block with the following procedure:

WS39930000) to lower cylinder block as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
After liquid gasket is applied, rear oil seal installation must
be finished within 5 minutes. Therefore, the following pro-
cedure must be performed quickly.
NOTE:
Lower cylinder block cannot be replaced as a single part,
because it is machined together with cylinder block.
b. Tighten lower cylinder block mounting bolts with the following
procedure:
i. Apply new engine oil to threads and seat surfaces of mounting bolts.
