Determine the size of the bearing I.D. 1. First choose the correct expanding driver from the listing below. Place the expanding driver onto the expander assembly. Be sure to line up each of the segments of the driver with the separa- tions on the expander assembly. Lubricate the smooth side of the rubber sleeve to help with putting the driver on the expander 2. Next place the nylon centering cone over the driving shaft. Now screw the expander assembly and driving washer from above on to the shaft. The kit comes with a driver shaft extension; this may be needed for removal of the rear bearings. .
