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 to the
specified torque. Refer to EM-249, "
ASSEMBLY" for the tighten-
ing procedure.
Measure the inner diameter of main bearing with bore gauge.
(Bearing 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-257,
"HOW TO SELECT MAIN BEARING" .
Method of Using Plastigage
Remove oil and dust on crankshaft main journal and the surfaces of each bearing completely.
Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
Install main bearings to cylinder block and main bearing caps, and tighten main bearing bolts with main
bearing to the specified torque. Refer to EM-249, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
Remove main bearing caps and bearings, and using scale on
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”.

CRUSH HEIGHT OF MAIN BEARING
When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-249, "
ASSEMBLY" for the tight-
ening procedure.
If the standard is not met, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING
When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-249,
"ASSEMBLY" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
DRIVE PLATE
Check drive plate and signal plate for deformation or cracks.
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. Standard : There must be crush height.
