Inspection procedure
Inspection: Connecting rod bearing span when free
CAUTION
• Do not attempt to manually expand the bearings.
• If the measurement is less than the limit, replace upper and low-
er bearings as a set.
Inspection: Connecting rod bearing-to-crankshaft oil clear-
ance
• Fit the lower bearing to the connecting rod cap and the upper
bearing to the connecting rod, then tighten the bolts to a torque
of 29 N
·m {3.0 kgf·m}.
• Measure the inside diameter of the bearing and the diameter of
the crankshaft pin.
• If the clearance exceeds the limit, replace the defective part(s).
• If a bearing has to be replaced with an undersized one, machine
the crankshaft pin to the specified undersize diameter. (See the
CRANKSHAFT section.)
Inspection: Piston-to-cylinder liner clearance
• If the measurement is not within the standard value range, re-
place the defective part(s).
A: Cylinder bore measurement (in direction of crankshaft axis)
B: Cylinder bore measurement (in direction perpendicular to
crankshaft axis)
C: Piston diameter measurement (in direction perpendicular to
piston pin hole)
