Removing, Replacing and Adjusting the Drive Belts
Tools Needed:
9/16" Wrench
3/8" Wrench
1/2" Wrench
Tape Measure
Straightedge
CHECKING AND ADJUSTING BELT TENSION
Note: The DR PRO-XL CHIPPER SHREDDER has two drive Belts. Due to factory
tolerances the tension on the two Belts may differ slightly. Over time the Belts will
stretch and will begin to closely match each other. This procedure only needs to be
performed on one Belt.
1.
Remove the three Bolts supporting the Belt Guard using a 3/8" Wrench
(
Figure 22
). Remove the Belt Guard and set aside.
2.
Place a Straightedge on the bottom of the Belt from the Clutch Pulley to the
Drive Pulley (
Figure 23
).
3.
Push up on the Belt using approximately ten pounds of force. The Belt
should deflect away from the Straightedge approximately 3/8".
4.
If the Belt deflection is close to the 3/8" as desired, adjustment is not
needed. If it is not close to 3/8", continue to the next step.
5.
Loosen the four Engine Bolts (two in the Front and two in the Rear) using a
9/16" Wrench (
Figure 24
).
6.
Tighten (turning clockwise) or loosen (turning counter clockwise) the
Tension Adjuster Bolt using a 1/2" Wrench to get the proper tension as
described in Step 3.
7.
Tighten the Engine Lock Nuts.
8.
Re install the Belt Guard.
Note:
Check and re-tighten the Drive Belts, every hour for the first 5 hours of
operation when a new Belt has been installed.
REMOVING AND REPLACING THE BELTS
When your DR PRO-XL CHIPPER SHREDDER’s Belts are no longer adjustable
or are frayed, cut or damaged, replace them with new DR Belts.
1.
Remove the three Bolts supporting the Belt Guard using a 3/8" Wrench
(Figure 22)
. Remove the Belt Guard and set aside.
2.
Loosen the four Engine Lock Nuts (two in the Front and two in the Rear)
using a 9/16" Wrench
(Figure 24)
.
3.
Loosen the Tension Adjuster Bolt, using a 1/2" Wrench and create enough
slack in the Belts to remove them from the Clutch and Drive Pulley
(Figure
23)
.
4.
Install the new Belts onto the Drive Pulley and Clutch Pulley.
5.
Re-tension the Belt per the Previous instructions “Checking and Adjusting Belt Tension”.
6.
Tighten the Engine Lock Nuts
(Figure 24)
