1) Place the crankshaft on two V-blocks.
2) Set a dial gauge on the surface plate and roll the crank-
shaft to measure its deflection.

Inspecting the Crankshaft Bearings and
Connecting Rod Bearings
1. Visual inspection
1) Check the crankshaft bearings and connecting rod bear-
ings visually for uneven wear, scratches or other damage,
and replace them if necessary.
2. Oil clearance between crankshaft and bearing
EDX22190058
1) Install the journal bearing on the cylinder block, tighten
the bearing cap to the specified torque, and measure the
inside diameter of the bearing.
EF8OM062
2) Install the bearing on the big end of the connecting rod,
tighten the bearing cap to the specified torque, and
measure the inside diameter.

3. Bearing oil clearance
1) Compare the measured bearing I.D. (journal bearing,
connecting rod bearing) with the measured crankshaft
journal and pin O.D. to calculate the oil clearance.
2) If the clearance is beyond the limit, grind the crank journal
and crankpin and select a suitable undersize bearing to
use.
