CYLINDER BLOCK
• Measure the outer diameter of crankshaft main journals with a
micrometer (A).
• If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Follow the "MAIN BEARING OIL
CLEARANCE" procedure.
CRANKSHAFT PIN JOURNAL DIAMETER
• Measure the outer diameter (Dp) of crankshaft pin journal with amicrometer.
• If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing. Follow the "CONNECT-
ING ROD BEARING OIL CLEARANCE" procedure.
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. Follow the "MAIN BEARING OIL CLEARANCE" and/or "CON-
NECTING ROD BEARING OIL CLEARANCE" procedures.
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 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.

• Install connecting rod bearings (2) to connecting rod (3) and con-
necting rod bearing cap (1), and tighten connecting rod bolts to the
specified torque. Refer to EM-196, "
Disassembly and Assembly"
for tightening procedure.
• 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 clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end diameter and crankshaft pin journal diameter to obtain specified bearing oil clearance. Refer to EM-205,
"How to Select Piston and Bearing".
Method of Using Plastigage
• 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-196, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Never rotate crankshaft.
• Remove connecting rod cap and bearing, and using the scale (A) 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 (3) to cylinder block (1) and main bearing cap(2), and tighten main bearing cap bolts to the specified torque.
Refer to EM-196, "
Disassembly and Assembly" for the tightening
procedure.
• Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
