9.Loosen the front drum pillow bearing lock nuts (Figure 51, Page 39).

10.Adjust the height of the front drum ends by adjusting the set screws (Figure 51) on the pillow bearing up or down until the largest size feeler gauge you can fit between the front drum and 36" long gauge blocks (at both ends) is 0.017"–0.025.

Note: The 0.017"–0.025" setting is a recommended range and includes the 0.010" setting on the rear drum and the additional 0.007" to 0.015" height from Step 12 (See Figure 58). Some trial-and-error may be needed to find the optimal setting based upon the sandpaper grit size you use (ie, coarse grit = smaller number; fine grit = larger number).

11.Tighten the front pillow bearing lock nuts.

12.Check to make sure that when you tightened the nuts the front drum did not move horizontally, and that the front drum is still parallel with the rear drum, using the small gauge blocks.

—If the gauge blocks are snug between the front and rear drums, go to Step 14.

—If the gauge blocks are not snug betwen the front and rear drums, repeat Step 11 and 12 on Page 39.

13.Calibrate the scale pointer as described on Page 43.

14.Remove all gauge blocks, reinstall the sandpaper on the drums, reinstall the V-belts, and close the pulley and top covers.
