Fitting the half bushing

Fit the thickness washers and the half bushing, positioning it as shown in the figure. The thickness washers must be positioned so that the half bushing upper face is 100 mm higher than the ignition distributor face. This is necessary to allow the distributor to block the central gear group and apply pressure against the distributor gasket. After this is done, the ignition distributor can be fitted. Once the distributor is fitted, check the play in the bevel gears to ensure that there is no play, but they should not be tight.
