| Specially-selected main and crankshaft
half-bearings are fitted to this engine to ensure that the matching
clearance is optimum. |
| The crankshaft is supplied, by
the Parts Dept., without the appropriate half-bearings for 'standard'
dimension main journals and crank pins; it is therefore necessary
to select the half-bearings to be fitted by 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 phonic wheel;
- 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 crankpins: the first two numbers on the left refer to the first
pin 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
84 (first on the left) corresponds to the dimension 52.984 for the
first bearing on the timing side which identifies Grade A (red colour);
the same method can be used for all 87 - 85 - 85 - 8497 - 95 -
95 - 94). MAIN JOURNAL IDENTIFICATIONGrade A main journal (standard), diameter
52.982 52.988 mm, RED paint mark, code number 1 (82 88)* Grade B main journal (normal), diameter

73)* (*) 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
obtain 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 0.031 0.051 mm;
this value can be measured, as a final check, using the Plastic
Gauge as described below. Place the main half-bearings, selected
as described above, back in their housings in the cylinder block/crankcase. | Observe scrupulous cleanliness
during assembly. |
1. Place the crankshaft back in its housing.2. Fit the calibrated wire (Plastigage) to measure the main journal
clearance.
1. Place the bearing cap (1a), complete with half-bearing, back
in its housing and secure it by tightening the nuts (1b) to the
