CRANKSHAFT RUNOUT
●Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.
●Place a dial gauge straight up on the No. 3 journal.
●While rotating the crankshaft, read the movement of the pointer
on the dial gauge. (Total indicator reading)
CONNECTING ROD BEARING OIL CLEARANCE
Method of Measurement
●Install the connecting rod bearings to the connecting rod and the
cap, and tighten the connecting rod bolts to the specified torque.
Using a inside micrometer measure the inner diameter of con-
necting rod bearing.
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
●If out of specifications, check connecting rod big end inner diam-
eter and crankshaft pin outer diameter, and select appropriate
connecting rod bearing to adjust clearance to specifications.
Refer to EM-83, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage
●Remove engine oil and dust on the crankshaft pin and the sur-
faces of each bearing completely.
●Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
●Install the connecting rod bearings to the connecting rod cap,
and tighten the connecting rod bolts to the specified torque.
CAUTION:
Never rotate the crankshaft.
●Remove the connecting rod cap and bearings, and using the
scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is same as that described in “Method of Mea-
surement”.
MAIN BEARING OIL CLEARANCE
Method of Measurement
●Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter
with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main bearing) – (Outer diameter of crankshaft journal)
●If out of specification, check main bearing housing inner diameter and crankshaft journal outer diameter,
and select appropriate main bearing to adjust clearance to specifications. Refer to EM-85, "

Precautions For Liquid GasketEBS00ODW
REMOVAL OF LIQUID GASKET
●After removing the mounting bolts and nuts, separate the mating
surface using a seal cutter and remove the old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
●In areas where the cutter is difficult to use, use a plastic hammer
to lightly tap the areas where the liquid gasket is applied.
CAUTION:
If for some unavoidable reason a tool such as a flat-blade
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove the old liquid gasket adhering to the liq-
uid gasket application surface and the mating surface.
●Remove the liquid gasket completely from the groove of the
liquid gasket application surface, mounting bolts and bolt
holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach the liquid gasket to the tube presser.
Use Genuine Liquid Gasket or equivalent.
4. Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
●If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
●As for the bolt holes, normally apply the liquid gasket inside
the holes. If specified, it should be applied outside the holes.
Make sure to read the instruction in this manual.
●Within five minutes of liquid gasket application, install the mat-
ing component.
●If the liquid gasket protrudes, wipe it off immediately.
●Do not retighten after the installation.
●After 30 minutes or more have passed from the installation, fill
the engine oil and engine coolant.
CAUTION:
If there are instructions in this manual, observe them.

Checking Drive BeltsEBS00LRA
●Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the engine has been
stopped.
●Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:
●When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing the crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.
●Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB
●Adjust belts with the parts shown below.
CAUTION:
●When a new belt is installed as a replacement, adjust it to the value specified under “New” value
because of insufficient adaptability with pulley grooves.
●If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
●When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.
●Make sure the belts are fully fitted into the pulley grooves during installation.
●Handle with care to avoid smearing the belts with engine oil or cooling water etc.
●Do not twist or bend the belts with strong force.
