1 Measure width of crankshaft fit bearing journal and assign matching thrust washers.
Thrust washers of the same thickness must be installed on both sides of the crankshaft fit bearings.
S03.20-3015-01
2 Oil top thrust washers and insert into the crankcase.
The two oil grooves (arrows) in the thrust washers must point toward the crankshaft webs.
S03.20-3016-01
3 Oil bottom thrust washers and insert into the grooves at crankshaft fit bearing cap.
The two oil grooves (arrows) in the thrust washers must point toward the crankshaft webs.
S03.20-3017-01
4 Oil crankshaft and insert.
5 Fit on crankshaft bearing caps according to marking.
6 Oil bolts of crankshaft bearing caps and tighten fully to specified torque.
S03.20-3018-01
7 Measure crankshaft bearing axial play.
If the measurement obtained is not within the permissible tolerance, correct axial play of crankshaft bearings by replacing the thrust washers, aim for the mean value of the specified axial play. Thrust washers of the same thickness must be installed on both sides of the crankshaft fit bearings.
8 Rotate crankshaft by hand and check unobstructed movement, re-mount crankshaft in bearings, if necessary.
