1

Measure width of fitted bearing at crankcase and at balance shaft housing and note it down.

2

Measure width of fitted bearing at crankcase and note it down.

3

Determine thickness of thrust washer.

 In the crankcase and balance shaft housing equally thick thrust plates must always be used on both sides.

4

Install thrust plates  .

 The oil grooves (arrows) must be pointing toward the contact surface of the crankshaft and be oiled. The anti-twist lock is positioned against the thrust plate in the balance shaft housing.

5

Measure axial bearing play, adjust if necessary   .
