Grizzly G1073/G1073Z instruction manual Motor Mount Bolts

Pulley alignment and belt tension should now be adjusted simultaneously.

1.Situate the motor so the V-grooves on the motor pulley approximately line up with the V-grooves on the three-step pulley. You may need to loosen the motor mount bracket bolts shown in Figure 9A to position the motor properly. Tighten the mount bracket to the stand before moving on to the next step. Leave the motor mount bolts loose.

If the pulleys will not align by moving the motor only, loosen the bandsaw mounting bolts and position the bandsaw so the step pulley aligns with the motor pulley. Leave the motor mount bolts loose.

2.Slide the motor up or down to achieve prop- er V-belt tension. You should be able to deflect the V-belt about 3Ú4" at its midpoint (see Figure 9B) using moderate finger pres- sure. Be careful not to change the lateral position of the motor and move the pulleys out of alignment. Tighten the motor mount bolts.

3.Check the pulley alignment with a plumb bob or straightedge. If you are using a plumb bob, the string must touch the outside flanges of each pulley evenly as shown in Figure 10, and the machine must be level.

4.Check V-belt tension. Repeat steps 1-4until both tension and pulley alignment are cor- rect.
