5.10.1 DRIVE BELT ADJUSTMENT
Check the condition of the drive belt annually or after
every 25 hours of operation, whichever comes first. If
the belt is cracked, frayed, worn or stretched, replace it.
Replace belt with original banded type belt only. Do not
use single type belts.
1. Place the chipper engagement lever in the START
position (see Figure 5.7).
2.
Shut engine off.
3. Remove the seven 5/16 x 3/4" bolts securing the belt
shield to the shield weldment. Remove the belt shield.
4. To increase tension on the belt, do the following:
a. Move the engagement lever to the CHIPPING

Locate the two 5/16 x 3" bolts and 5/16" flange
nuts located on the side of the chipper between
the trailer and the engine plate (see Figure 5.9).
d. Tighten both 5/16" bolts equally to move the
engine away from the chipper housing until the
belt deflection is about 7/16" when a 20 lb. load is
placed against the belt (see Figure 5.9).
e. Tighten the four carriage bolts securing the
engine plate to the trailer.
f.
Tighten both 5/16" flange nuts to ensure the
proper deflection is maintained.

engine plate to the trailer.
f.
Tighten both 5/16" flange nuts to ensure the
proper deflection is maintained.
6. If the bolts and nuts between the engine plate and the
trailer cannot be adjusted any further, and the tension
needs further adjustment, tighten the eyebolt until the
appropriate deflection is achieved.
7.
Replace the belt if no adjustment is left (Section 5.10.2).
8. Reinstall the belt shield.
