Check that the oil ways of the bearings match up with the oil ways in the block.

Caution:  Before removal and fitting of the crankshaft ensure that the pressure relief valve has been removed.

Notes:

For emissions approved engines. The fuel adjustment screw must not be altered from the original setting.

The maximum No Load Speed must be checked after assembly.

If a new crankshaft is fitted, see Operation 3-13.

1  Identify position of bearing carriers on shaft.

2  Install bearing carriers on the crankshaft ensuring oil holes align with feed holes in cylinder block.

3  Check end float.

4  Check number 2 bearing holder on 102-05 engines and number 3 bearing holder on 103-07 and 103-10

engines for wear, poor contact, look burnt or other defects. Defective bearing holders must be renewed.

Notes:

For emissions approved engines. The fuel adjustment screw must not be altered from the original setting.

The maximum No Load Speed must be checked after assembly.

3  Check end float clearance (A2).

Note:  Ensure that the thrust washers are aligned correctly, and are fitted with their oil grooves towards the

crankshaft.

4  Check the thrust washers for wear, poor contact, look burnt, or have any other defects. Defective washers

must be renewed.

Note:  Item (A1) is only used on 104-19 and 104-22 engines.
