Inspection
1. If the length ‘L’ of the crankshaft bearing cap bolt exceeds
63.8mm, replace it.
2. Make sure the crankshaft bearing cap is properly seated
on the cylinder block (arrows).
3. Measure and record the inner diameter of the crankshaft
bearing.
Notice
lMeasure at 2 points (1, 2).
lMeasure ‘A’,‘B’and ‘C’ as shown. If average value of
‘B’ and ‘C’is less than value ‘A’, then the average value
of ‘B’ and ‘C’ is actual average value. If average value
of ‘B’ and ‘C’ is more than value ‘A’is actual average
value.
4. Measure and record the diameter of the crankshaft
bearing journal.
Notice
lRecord the mean value when measured at 3 points
(A, B, C).
lMeasure the inner diameter of bearing and the
diameter of journal and if it is out of the standard data,
replace the bearing shell.
