2.Install the pillow block bearing loosely. Secure the rear bearing to the center frame.
3.The shaft should be parallel to the sides of the chassis (Figure 81). The pillow block bearing has slotted mounting holes to provide adjustment. Tighten the cap screws on the pillow block bearing. While rotating the pulley, strike the pillow block bearing with a rubber mallet (Figure 82). This helps the bearing align itself with the shaft. If the shaft turns with difficulty, loosen the cap screws on the pillow block bearing and rotate the pulley. Then secure the cap screws.
