(3) Crankshaft run-out
•
Support the crankshaft on V blocks.
•
Turn the crankshaft with a dial indicator
placed on the surface plate and take the
amount of crankshaft run-out.
2) Crankshaft bearing and connecting rod
(1) Visual check
Visually check the crankshaft bearing
and connecting rod bearing for scores,
uneven wear or damage.
(2a) Oil clearance between crankshaft
and bearing (Method 1 : dial gauge)
•
Main bearing clearance
Install the main bearing in the cylinder
block, tighten the bearing cap to speci-
fied torque, then measure the inside
diameter.
Compare the two values
obtained through measurement of
main bearing inside diameter with
the outside diameters of crank-
shaft journals to determine the oil
clearance.
