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).

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.
