 Roller removal.

Check the V-belts periodically to check for signs of 

glazing, cracking or fraying. If any of these conditions 

are present, change both V-belts. In order to take the 

V-belts off of the roller pulleys, the rollers must be 

removed from the sander.

Change the V-belt as follows:

1.

  DISCONNECT THE SANDER FROM POWER AND AIR 

PRESSURE!

2.

  Loosen the V-belts and remove them from the motor 

pulley. Refer to 

V-Belt Tension

 for any needed 

details on 

Page 29

.

 

3.

  Open both access doors on the upper part of the 

machine. At the left-hand access side, remove the 

platen knob by loosening the setscrew near its dial. 

4.

  Remove the two setscrews that secure the dial plate 

to the casting and then remove the two large cap 

screws that secure the top of the casting.

5.

  Pull the casting off of the roller ends as shown in 

Figure 27

6.

  At the other side of the machine (the right-hand 

side from the front), remove the large nut shown in 

Figure 28

.

 The roller may turn if not held from the 

other side.

 This secures the other end of the front 

roller shaft to the sander body. 

7.

  Now, move back to the left-hand side of the 

machine and carefully pull out the front sanding belt 

roller as shown in 

Figure 29

. The V-belts can now 

be easily removed. 

8.

  Install the new V-belts in the reverse order of 

removal. 

To make this process easier, have a helper 

hold the V-belts up at the other side of the sander 

when you re-install the roller. When you retighten 

the large roller shaft nut, have your helper stand at 

the other side of the sander to keep the roller from 

turning.
