18 DR ® CHIPPER/SHREDDER
Grease Fittings
Your DR CHIPPER/SHREDDER was greased at the Factory. The operator needs
to lubricate the Chipper Side and Drive Side Bearings periodically.
Tools and Supplies Needed:
 Flexible hose grease gun
 Lithium grease

Clean cloth

5/32" Allen Wrench
 Loctite ® 243 (if needed)
1. Wipe all dirt, etc., from the Grease Fitting(s) with a clean cloth (Figure 14).
2. Apply no more than three pumps of quality general-purpose lithium grease
with a hand-pumped grease gun to each Grease Fitting, one on the Chipper
Side Bearing, and one on the Drive Side Bearing (not shown). To access the
Drive Side Bearing, you will have to remove the Belt Guard (see below).
3. After greasing, check the Side Bearing Collar Set Screws (Figure 14) for
tightness with a 5/32" Allen Wrench. There are two Set Screws per Bearing.
If they are loose, reset them with Loctite
® 243, obtainable at most hardware
stores.
Adjusting or Removing and Replacing the Drive Belt
Tools and Supplies Needed:

(2) 1/2" Wrench

5/32" Allen Wrench and Snap Ring Pliers (if needed)

Loctite ® 243 (if needed)
 Straight Edge
1. Remove the Belt Guard by removing the retaining Nuts, Washers, and Bolts using two 1/2" Wrenches. Note the placement of
Flat Washers for re-assembly.
2. The Belt should deflect 3/8" under approximately three pounds of pressure as shown in Figure 15, if it doesn’t, adjust per the
following directions.
3. Remove the Baffle Plate (see Figure 11 on page 16).
4. Loosen the four Engine Bolts (2 in the Front and 2 in the Rear) using two 1/2" Wrenches (Figure 16 on page 19).
5. Using two 1/2" Wrenches, hold the Belt Adjust Nut while turning out the Jam Nut (Figure 17 on page 19).
NOTE: If you are replacing the Belt, turn the Adjust Nut out to allow slack in the Belt.
6. Turn the Adjust Nut in to tighten or out to loosen for the correct Belt deflection (Figure 15).
Use only a DR Belt on your machine. The Belt has been thoroughly tested and proven for many hours of use.
