Removal
Mark the position of the original semi-bushings on the crankcase.
To reduce the installation force necessary, score an incision approximately 0.5 mm (0.02 in) deep (without cutting into the steel shell) in each semi-bushing in the area indicated in the figure.
Remove the bushings with the crankcase cold, using a press and the specific tool and pushing inward from the outside of the crankcase.

Installing
The orientation of the semi-bushings must match the specifications indicated in the drawing as closely as possible.
Key: * Semi-bushing joint line
Note. When replacing the semi-bushings alone, the new components must be the same colour as the removed components. If the colour of the old components is no longer visible, use the table to identify the correct components, referring to the crankcase and crankshaft classes.
Fit the new bushings with the crankcase cold, using a press and the specific tool and pushing outward from the inside of the crankcase, until the punch comes into contact with the crankcase surface.

Assembling the connecting rod
Caution! To fit the connecting rods, check the coupling types indicated in the "Crankcase - crankshaft", in the "Characteristics" chapter of the workshop manual.
