1 Measure width of fit bearing at crankcase and at fit bearing cap, note.
2 Measure width of fit bearing at crankshaft, note.
3 Determine thickness of thrust washer
Thrust washers of the same thickness must always be inserted in the crankcase and in the fit bearing cap.
Shims are available in thicknesses from 2.15 up to 2.40 mm in graduations of 0.05 mm.

4 Install thrust washers
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 washer in the bearing cap.
