Place the jets back in their housings in the crankcase and secure them using the bolts.Place the thrust washers back in their housings in the third bearing support.Main journal half-bearings have been fitted on crankshafts which have been selected so that the matching clearance is optimum.

The crankshaft is supplied,bythe Parts Dept.,without the appropriate half-bearingsfor 'normal' dimension main journals and crank pins; it is therefore necessary to select the main journal half-bearings to be fitted identifying the grade for each main journal and crank pin for the new crankshaft.

The following is needed for selecting the main journal half-bearings: the code number stamped on the flywheel; the paint mark, if present, next to the main journals.Below is an example of the identification of main journal grades. 1 - Crank pin identification number: the number on the left refers to the first timing side bearing; the final 'N' is a code that does not matter for 4 cylinder engines. 2 - Main journal identification code: the first number on the left refers to the first timing side bearing; the final 'N' is a code that does not matter for 4 cylinder engines. 3 - Set of numbers (if present), in groups of two digits, which indicate the dimensions (thousandth part) of the main journals: the first two numbers on the left refer to the first bearing on the timing side.

Only use the codes in the key, all other codes on the flywheel should not be used.

For the identification of the main journal grade, refer to the numerical code for reference 2 in the key.In the case of the example, the numbers 11111N indicate that all five bearings are Grade A (red colour) as described below.A further method for identifying the grade of the bearings is to read reference 3 in the figure (if present).In the case of the example, the number 94 (first on the left) corresponds to the dimension 59.994 for the first bearing on the timing side which identifies Grade A (red colour); the same method can be used for all the other groups of two digits for the same reference 3 (97 - 95 - 95 - 94). MAIN JOURNAL IDENTIFICATIONGrade A main journal (normal), diameter 59.994 60.000 mm, RED paint mark, code number 1 (94 00)*Grade B main journal (normal), diameter 59.988 59.994 mm, BLUE paint mark, code number 2 (88 94)*Grade C main journal (normal), diameter 59.982 59.988 mm, YELLOW paint mark, code number 3 (82 88)*Grade D main journal (0.127mm undersize) diameter 59.867 59.873 mm, BROWN paint mark, code number 6 (67 73)*Grade E main journal (0.127 mm undersize) diameter 59.861 59.867 mm, GREEN paint mark, code 7 (61 67)*Grade F main journal (0.127 undersize) diameter 59.855 59.861 mm, BLACK paint mark, code number 8 (55 61)* (*) Last two numbers (thousandth part) of the dimensions of the main journals.If a crankshaft is being used where the maximum bearing undersize through regrinding is 0.127 mm, then the grade should be selected by measuring the dimensions of the diameter of the bearing with reference to the above. Having defined the grade and colour for each new or reground crankshaft bearing, it is necessary to select the pair and the size for the bearings which should be the same colour as the corresponding bearing; at the Parts Dept. it is possible to go back to the part no. of the pair of half-bearings required. The above is designed to ensure the optimum operating clearance for all bearings.Lastly, we wish to point out that, usually, the clearance between the main journal and the half-bearing, produced by the selection method described above, should be between the following figures: Minimum: 0.011 mm - Maximum: 0.071 mm; this value can be measured, as a final check, using the Plastic Gauge.Place the upper half-bearings back in their housings in the cylinder block/crankcase.Place the crankshaft back in its housing on the crankcase.1.
