Adjusting V-Belt
Tension
Properly tensioned V-belts help the Model G0504
operate at its best. However, adjusting the V-
belts is not an exact science and does require
personal judgement. Adjusting the belts too loose
will decrease the performance of the machine
and adjusting the belts too tight may cause pre-
mature wear of the bearings and other compo-
nents attached to the belts.
On the Model G0504 there is a triple-drive V-belt
system that connects the motor to the wheel
pulley and a single-drive V-belt system that con-
nects the wheel pulley to the hydraulic pump
(
Figure 35).

To adjust the V-belt tension for the saw
wheels:
1. Disconnect the resaw from the power
source!
2. Adjust the belt tension by using the motor
mount hex bolts shown in Figure 36.
3. When the belts are properly tightened, lock
the bolts in place with the jam nuts.
To adjust the tension for the hydraulic pump
V-belt:
1. Remove the small pulley cover from the
pump seat.
2. Adjust the belt tension by loosening the cap
screws shown in Figure 37.

3. Slide the pump left/right as needed until the
belt has the proper tension.
4. Tighten the cap screws to lock the pump
seat in place.
