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

z

Measure at 2 points (1, 2).

z

Measure ‘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

z

Record the mean value when measured at 3 points (A,
B, C).

z

Measure the inner diameter of bearing and the diameter
of journal and if it is out of the standard data, replace
the bearing shell.
