Undersize Bearings Usage Guide
• When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod bearings, use undersize (US) bearings.
• When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to u se undersize bearings, keep the
fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).

(Y) directions at (A), (B) and (C)] [(Y) is in longitudinal direction of
engine].

specified torque. Refer to EM-200, " Disassembly and Assembly "
for tightening procedure.
• Measure the inner diameter of connecting rod bearing with an inside micrometer.

torque. Refer to EM-200, " 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”.
