CLASSIFICATIONANDALLOCATIONOF THRUST
WASHERS
The selection of thrust washers for the centre main
journal should be made using reference 3 in the
diagram (i.e. R for the normal size, RM for a 0.127
mm oversize), therefore the selection should be made
using the crankshaft end float measured previously.
Half ring grade
Thickness
grade R (normal )
2.310 - 2.360 mm
grade RM (0.127 mm oversize)
2.437 - 2.487 mm
This value can be measured, as a final check, using
the calibrated wire (plastic gage).
Crank pin grade

grade A (normal) 42.600 - 42.5914 mm RED paint mark
grade B (normal), 42.591 - 42.582 mm, BLUE paint mark
grade AM
(0.127 undersize) 42.473 - 42.464 mm BROWN paint mark
grade BM
(0.127 undersize) 42.464 - 42.455 mm GREEN paint mark
CLASSIFICATION OF CRANKPINS AND
ALLOCATIONOF HALF-BEARINGS
The procedure described for the main journal half-
bearings should also be carried out for selecting the
crankpin half-bearings.
By way of example, if the alphabetical code identified
is the one indicated by reference 1 in the diagram,
i.e. - BBBB, this means that the four crankpins are all
Grade B (to which a specific diameter belongs) and
are therefore ready for the fitting of half-bearings with
a blue coloured paint mark on the edge.
The first letter on the left - B of the alphabetical code
is always related to the first timing side crankpin.
Refer to the instructions above for the pair of half-
bearings to be allocated to each bearing.
