| The main and connecting rod half-bearings used on this engine have been selected for their optimum fitting clearance. |
| 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 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 84 (first on the left) corresponds to the dimensions 52.984 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 (87 -85 -85 -84).MAIN JOURNAL IDENTIFICATIONMain journal grade A (normal), diameter 52.982.52.988 mm, RED paint mark, numerical code 1 (82 88)*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 52.994.53.000 mm, YELLOW paint mark, numerical code 3 (94 00)*Main journal grade D (0.127 mm undersize), diameter 52.885.52.861 mm, BROWN paint mark, numerical code 6 (55 61)*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 52.867.52.873 mm, BLACK paint mark, numerical code 8 (67 73)*(*): 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 half-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,in general, the clearance between the main journal and the half-bearing, produced through the selection method described above, should be 0.031 - 0.051 mm; this figure can be measured, as part of the final check, using the calibrated wire (Plastic Gauge) following the instructions described below.Place the half-bearings back in their housings in the engine block as described previously. | Great care should be taken over cleanliness when refitting. |
1. Place the crankshaft in its housing.2. Fit the calibrated wire (plastigage) for measuring the bearing clearance.
1. Place the bearing cap (1a), complete with half-bearing, back in its housing and secure it tightening the bolts (1b) to the recommended torque. | The bearing caps are marked with progressively numbered references (from zero to four starting from the front of the engine) which define the fitting position. |
| The safety references on the cylinder block/crankcase and on the bearing caps should be on the same side. |

| If the figure measured is outside of the tolerance, replace the half-bearings with ones of the correct size and category. |
Place the half-bearings in their seats.Place the thrust washers (with the size depending on the crankshaft endfloat measured during the dismantling) in their housings in the third bearing support. | The thrust washer lubrication ducts should be facing the crankshaft thrust washers. |
Place the crankshaft in its housing.1. Place the bearing caps (1a), complete with half-bearing, back in their housings and secure them tightening the bolts (1b) to the recommended torque. | The bearing caps are marked with progressively numbered references (from zero to four starting from the front of the engine) which define the fitting position. |
