To inspect

Operation 5-9

Check the crankshaft for wear and other damage. The maximum permissible wear and ovality on the

crankshaft journals is 0,05 mm (0.002 in). The maximum permissible wear and ovality on the crank pins is

0,0075 mm (0.00025 in).

The main journals and the crank pins of standard size crankshafts can be machined to 0,25 mm (0.010 in),

0,50 mm (0.020 in) or 0,75 mm (0.030 in) undersize on diameter. Refer to the relevant Data and dimensions

for the "Crankshaft assembly" on page 14. Special undersize bearings are available.

Crankshaft gear

To renew

Operation 5-10

Warning! Use suitable gloves to protect the hands from heat.

Caution: If the crankshaft gear is to be renewed, the drive spline for the oil pump has to be renewed also.

1  Remove the crankshaft, see Operation 5-7.

2  Put a suitable support (A3) under the crankshaft nose.

Caution: Do not scratch or damage the crankshaft with the chisel or the hammer. If the crankshaft is scratched

or damaged, it will have to be reground or renewed.

3  Use a hammer and chisel to break the drive spline (A2) for the oil pump, and to break the crankshaft gear

(A1).

4  Remove the drive spline for the oil pump, and remove the crankshaft gear.

5  Clean the crankshaft nose.

Caution: Do not fit a cold crankshaft gear, it will be damaged.

6  Heat a new crankshaft gear to 370/395 °F (188/202 °C).

7  Press the crankshaft gear (B2) onto the crankshaft (B4). Ensure that the locating pin (B1) engages in the

crankshaft gear.

Caution: Do not fit a cold drive spline, it will be damaged.

8  Heat a new drive spline for the lubricating oil pump to 370/395 °F (188/202 °C).

9  Press the drive spline (B3) onto the crankshaft.

Thrust bearing

To check crankshaft end-float

Operation 5-11

Note: The axial movement of the crankshaft is controlled by a thrust bearing (A1) in the rear (number 7) main

bearing cap. The end-float can be checked with a dial test indicator on one end of the crankshaft.

1  Put a dial test indicator (B2) against the face of the crankshaft flange (B3).

2  Use a lever (B1) to move the crankshaft fully toward the front of the engine and set the indicator to zero.

3  Use a lever to move the crankshaft fully toward the rear of the engine and note the indicator reading.

4  Renew the thrust bearing if the end-float is more than the tolerance given in the relevant Data and

dimensions for the "Crankshaft assembly" on page 14.
