CRANKSHAFT PIN JOURNAL DIAMETER
Measure outer diameter of crankshaft pin journal with microme-
ter.
If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-263,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER
Measure the dimensions at four different points shown in the fig-
ure on each main journal and pin journal with micrometer.
Out-of-round is indicated by the difference in dimensions
between “X” and “Y” at “A” and “B”.
Taper is indicated by the difference in dimension between “A”
and “B” at “X” and “Y”.
If the measured value exceeds the limit, correct or replace crankshaft.
If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
