Crankshaft
If the connecting rod bearing is replaced, take care to properly
position the coupling shaft. The holes in the shaft section A and
in the coupling shaft B must be aligned.
IF THE COUPLING SHAFT IS FORCED IN OUT OF PO-
SITION, THE CONNECTING ROD BEARING WILL RE-
CEIVE LITTLE OR NO OIL AND WILL CONSEQUENTLY
BE DAMAGED.
If the crankshaft is to be reused, be sure to check the offset of
the shaft sections. Place the crankshaft on a roller equalizer or
similar equipment and use a comparator to measure the offset
at the ends of the shaft sections.
Offset of shaft sections: ≤ 0.08 mm
Check the radial and axial plays of the connecting rod bearing.
Radial play: ≤ 0.05 mm
Axial play: ≤ 1.10 mm
