The thrust plates are assigned to the fitted bearing cap using the numbers 1 and 0 (arrow). These are engraved on the journal of the crankshaft.
The fitted thrust plates must have the same identification and the oil grooves of the thrust plates must point to the crankshaft journals.

Install dial indicator (2) with extension and
dial indicator holder (1).
- Press crankshaft with a screwdriver on one side up to support (arrow) and hold.
- Set scale of
dial gage (2) to zero.
- Press crankshaft with a screwdriver on the other side up to support (arrow) and hold.
- Read off the measured value on the
dial indicator (2).
The measured value corresponds to the axial play of the crankshaft.
