The following must be determined for the selection of main journal half-bearings:The following must be determined for the selection of main journal half-bearings:
- the numerical code 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 - Crankpin identification numerical code: the left number refers to the first timing side bearing; the final "N" is an insignificant code for 4 cylinder engines.2 - Main journal identification numerical code: the first number refers to the first timing side bearing; the final "N" is an insignificant code for 4 cylinder engines.3 - Series 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 timing side bearing | Only use the codes that relate to 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) as indicated below.A further method for identifying the grade of the bearings is to read reference 3 (if present) in the diagram.In the case of the example, the number 94 (first on the left) corresponds to the dimensions 52.994 for the first timing side bearing which identifies Grade A (red); the same method should be applied for other groups of two digits for the same reference 3 (97 -95 -95 -94).MAIN JOURNAL IDENTIFICATIONMain journal grade A (normal), diameter 52.994.53.000 mm, RED paint mark, numerical code 1 (94 00)*Main journal grade B (normal), diameter 52.982.52.994 mm, BLUE paint mark, numerical code 2 (88 94)*Main journal grade C (normal), diameter 52.982.52.998 mm, YELLOW paint mark, numerical code 3 (82 88)*Main journal grade D (0.127 mm undersize), diameter 52.867.52.873 mm, BROWN paint mark, numerical code 6 (67 73)*Main journal grade E (0.127 mm undersize), diameter 52.861.52.867 mm, GREEN paint mark, numerical code 7 (61 67)*Main journal grade F (0.127 mm undersize), diameter 52.855.52.861 mm, BLACK paint mark, numerical code 8 (55 61)*(*): Last two numbers (thousandth part) of the main journal dimensions.- In the case of the usage of a crankshaft where the maximum undersize for the bearings is 0.127 mm through grindings, the grade should be selected through the measurement of the diameter of the bearing using the above as a reference.Having defined the grade and the colour of each new or reground crankshaft bearings, it is necessary to select the thickness of the bearings that should be the same colour as the corresponding bearing; the pair of half-bearings required can be ordered from the Parts Dept. by quoting the order no.The above is designed to guarantee the optimum operational clearances for all the bearings.Lastly, we wish to point out that, generally, the clearance between the main journal and the half-bearing, obtained through the selection method indicated above, should be within the following values:
- Minimum: 0.031 mm - Maximum: 0.051 mm; this value can be measured, as a final check, using the calibrated wire (plastic gauge).

Position the cylinder head on the cylinder block/crankcase taking care to ensure that the camshafts are positioned with the front cams facing outwards (valves closed). | Do not reuse the cylinder head bolts more than four times because they undergo permanent lengthening whenever they are tightened.Replace the bolts if the number of times that the bolts have been tightenened to the cylinder head is unknown. |
