[After removing the original bad pot metal bearing and cleaning out the shaft opening, the new mandrel shaft roller bearings are installed one at a time, first one from the left, then the one from the right. The left one is installed to the exact position desired, then the right bearing is installed next to the first bearing. Bearings are installed by using a bolt, washers, and a nut to draw the bearing into the shaft. Do NOT use a hammer! Detailed instructions with photos are provided.
