- Fit the thrust washers on the fourth bearing support.

The crankshaft supplied by the Parts Dept. comes without half-bearings and the main journals and crankpins are the "normal" size; the half-bearings to be fitted must therefore be selected identifying the class of each main journal and crankpin for the new crankshaft.

- 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 number on the left refers to the first timing side bearing; for 4 cylinder engines, there is an "N" in place of the number for the 5th bearing- 2. - Main journal identification numerical code: the first number on the left refers to the first timing side bearing; for 4 cylinder engines, there is an "N" in place of the number for the 6th bearing- 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 case of the example, the numbers 111111 indicate that all six bearings are Grade A (red) as indicated in the Table.- 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 59.994 for the first timing side bearing which, as indicated in the Table, 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 - 95).- Bearing grade A - Normal, diameter (mm) 59.994 - 60.000, paint mark, numerical code 1 (94 00)°- Bearing grade B - Normal, diameter (mm) 59.987 - 59.993, paint mark, numerical code 2 (88 94)°- Bearing grade C - Normal, diameter (mm) 59.982 - 59.986, paint mark, numerical code 3 (82 88)°- Bearing grade D - Undersize, diameter (mm) 59.867 - 59.873, paint mark, numerical code 6 (67 73)°- Bearing grade E - Undersize, diameter (mm) 61 - 59.866, paint mark, numerical code 7 (60 67)°- Bearing grade F - Undersize, diameter (mm) 55.885 - 59.859, paint mark, numerical code 8 (55 61)°- (*) 0.127 mm undersize- (°) 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 Table 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: - - Maximum: -; this value can be measured, as a final check, using the calibrated wire (plastic gauge).1.
