If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer
to EM-136, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage

Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding
oil holes.

Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-128, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod bearing 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 the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation

Install main bearings to cylinder block and main bearing caps,
and tighten main bearing cap bolts with main bearing beam to
the specified torque. Refer to EM-128, "
ASSEMBLY" for the
tightening procedure.

Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)

If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diam-
eter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-137,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage

Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding
oil holes.

Install main bearing to cylinder block and main bearing cap, and tighten main bearing bolts with main
bearing beam to the specified torque. Refer to EM-128, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Never rotate crankshaft. Standard : 0.034 - 0.059 mm (0.0013 - 0.0023 in)
(actual clearance)
Limit : 0.070 mm (0.0028 in)

CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter “d” at position shown in the figure.

If the reduction appears in a position other than “d”, regard it as
“d”.

When “d” exceeds the limit (when it becomes thinner), replace
connecting rod bolt with new one.
DRIVE PLATE

Check drive plate and signal plate for deformation or damage.
CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it.

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate.
OIL JET

Check nozzle for deformation and damage.

Blow compressed air from nozzle, and check for clogs.

If it is not satisfied, clean or replace oil jet.
OIL JET RELIEF VALVE

Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.

If it is not satisfied, replace oil jet relief valve. Standard : 7.90 - 8.00 mm (0.3110 - 0.3150 in)
Limit : 7.75 mm (0.3051 in)
