ENGINE 1.3 QUADRAJET (75PS) 56 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 Diameter Paint Mark 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 halfbearings 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 halfbearings to be allocated to each bearing.
