z
Assemble the bearing at the
bigger end of connecting rod, and
after tightening the bearing cap at
the specified torque, measure the
diameter.
z
Crankshaft pin and bearing
clearance In case that this
clearance value exceeds the limit
value, grind the crankshaft journal
and pin and then use the
undersized bearing.
b) How to utilize plastic gauge
z
Install the crankshaft in the cylinder block and place the plastic gauge on the crankshaft
journal and pin at axial direction and then after tightening the bearing cap at the specified
torque and again after tearing apart the bearing cap, measure the flatten plastic gauge
thickness by pick it up. This is the oil clearance.
z
With the same points, the oil clearance of connecting rod also can be measured.
c) End play
z
Assemble the crankshaft in the
cylinder block.
z
Install the dial gauge, and
measure the end play of
crankshaft by pushing the
