CYLINDER BLOCK
• Measure the outer diameter (Dp) of crankshaft pin journal with a
micrometer.
• If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
• Measure the dimensions at four different points as shown on eachmain journal and pin journal with a micrometer.
• Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
• Taper is indicated by the difference in dimension between “A” and “B” at “X” and “Y”.
• If the measured value exceeds the lim it, correct or replace crankshaft.
• If corrected, measure the bearing oil clearance of t he corrected main journal and/or pin journal. Then select
main bearing and/or connecting rod bearing.
CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on the both end of crankshaft.
• Place a dial indicator (A) straight up on the No. 3 journal.
• While rotating crankshaft, read t he movement of the pointer on the
dial indicator. (Total indicator reading)
• If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
• Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified torque. Refer to EM-90, "
Disassembly and Assembly".
• Measure the inner diameter of connecting rod bearing with an inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
• If the clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to EM-106, "
Connecting Rod Bearing".
Method of Using Plastigage
Standard : Refer to EM-116, "Cylinder Block".

• Remove engine oil and dust on crankshaft pin 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 c ap, and tighten connecting rod bolts to the specified
torque. Refer to EM-90, "
Disassembly and Assembly".
CAUTION:
Never rotate crankshaft.
• Remove connecting rod cap and bearing, 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 cap, and tighten main bearing cap bolts to the spec-ified torque. Refer to EM-90, "
Disassembly and Assembly".
• Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
• If the clearance exceeds the limit, select proper main bearing according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-108, "
MainBearing".
Method of Using Plastigage
• Remove engine oil and dust on crankshaft main 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 bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-90, "
Disassembly and Assembly".
CAUTION:
Never rotate crankshaft.
• Remove main 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”.
