Inspection

14. Check front web of crankshaft to determine if

main bearing journals have been ground
undersize.
No paint mark - Standard journals
1 paint mark - Journals are 0.25 mm (0.01 in)
undersize
2 paint marks - Journals are 0.50 mm (0.02 in)
undersize

NOTE: Each of the three main journal sizes
has a triple colour classification which
corresponds to the colour code of the

main bearing cap shells, a colour code on the
edge of the balance webs will indicate the actual
size.

15. Measure and record main journal diameters and

compare with the sizes given below. Take 4
measurements of each journal at 90

°

intervals to

check for appropriate specified size and ovality.
Standard:
Yellow = 59.984 to 59.990 mm (2.3616 to 2.3618
in)
Green = 59.977 to 59.983 mm (2.3612 to 2.3615
in)
White = 59.971 to 59.976 mm (2.3610 to 2.3611
in)

Undersize 1 - 0.25 mm (0.01 in):
Yellow = 59.734 to 59.740 mm (3.3522 to 2.3526
in)
Green = 59.727 to 59.733 mm (2.3514 to 2.3520
in)
White = 59.721 to 50.726 mm (2.3512 to 2.3514
in)

Undersize 2 - 0.50 mm (0.02 in):
Yellow = 59.484 to 59.490 mm (2.3418 to 2.3420
in)
Green = 59.477 to 59.483 mm (2.3414 to 2.3417
in)
White = 59.471 to 59.476 mm (2.3413 to 2.3415
in)

16. If standard or undersize 1 journals are found to

be oval, the crankshaft may be ground to the
next undersize.

17. If journals are worn below the original colour

code size but ovality is within limits, then the
next size main bearing shells should be fitted in
the main bearing caps and cylinder block when
carrying out the Plastigage check.

NOTE: If journals are worn below the
lowest colour size for standard or
undersize 1 journals, crankshaft may be

ground to the next undersize. Ensure that paint
stripe(s) to denote that grinding has been carried
out are marked on the crankshaft front web.
