INSPECTING THE CONNECTING ROD OIL CLEARANCE
(1)
Use the micrometer to measure an outer diameter of a crank pin
on the crankshaft. If a measurement reading exceeds the permis-
sible limit, grind or replace the crankshaft.
! CAUTION
•
If the crankshaft is ground, use an undersize bearing.
•
If uneven wear is 0.1 mm {0.0039 in.} or larger, regrind for
correction. If wear is 0.2 mm {0.0079 in.} or larger, regrind. If
wear is 0.7 mm {0.0276 in.} or larger, replace the crankshaft.
NOTICE
When grinding the crankshaft, adjust a fillet radius dimension as
indicated below.
Crank pins: 2.5-3.0 mm {0.0984-0.1181 in.}
(2)
Mount the bearing to the connecting rod large end. After mounting
the cap, tighten the connecting rod bolt with the specified torque.
(3)
Use the cylinder gauge to measure the bearing inner diameter of
the connecting rod large end.
(4)
Calculate the difference between the crank pin outer diameter of
crankshaft and the connecting rod bearing inner diameter. If a
measurement reading exceeds the permissible limit, replace the
connecting rod bearing or crankshaft.
