Figure 11: Rotating the machine casting to remove the disc guard bolts
6.Remove the two bolts, underneath the machine casting, that secure the disc guard to the casting (See Figure 11).
Figure 12: Locating the set screws that secure the disc to the arbor
5.Through the hole in the disc guard casting, locate and remove the TWO set screws that secure the drive disc to the arbor. One set screw clamps on the arbor key and the other clamps on the arbor shaft, itself. Be sure you loosen both of them.
Figure 13: Removing the guard and drive disc, together.
6.Slide the disc and its guard off of the machine, together (See Figure 13).
7.The V-belt can now be removed from the drive arbor.
8.Install the new belt on the top pulley.
9.Slide the disc and guard back into position.
10.Reinstall the disc guard bolts underneath the table.
11.Position the drive disc so that it is no more than 1/16 inch away from the table, then tighten BOTH of the set screws by inserting the hex wrench through the hole in the disc guard casting.
12.Rotate the machine back onto its base and secure it with all four mounting bolts.
13.Install the belt over the bottom pulley.
14.Tension the belt so that when pressed, in the middle of its travel, it has no more than one belt's width of movement -- then tighten the four motor bolts.
15.Observe the alignment of the motor pulley and arbor pulley. If necessary, correct their alignment by shifting the motor slightly on its mount (which involves loosening and retightening the mounting bolts and checking tension) or by shifting the pulley slightly on the motor shaft (which in- volves loosening the motor pulley set screw and sliding the pulley into alignment) or by moving the arbor pulley slightly on its shaft (See Figure 14).
16.When the pulleys are accurately aligned, reinstall the belt guard.
17.Reestablish electrical power to the machine.
