5.4 REPLACING THE HYDRAULIC
DRIVE BELT (HONDA ONLY)
Check the condition of the hydraulic drive belt annually, or
after every 25 hours of operation. Replace the belt if cracked,
worn, frayed, or stretched.
To replace:
1. Loosen the mounting bolts shown in Fig. #29.
2. Loosen the nut (not shown) on the back side of the ad-
justing bolt to relieve tension on the belt. Make sure that
the pump mounting bracket moves and relieves the belt
tension.
3. Remove drive belt according to instructions on prior page.
4. Remove the loosened hydraulic belt from the chipper.
5. Install the new hydraulic belt in the same manner as you
removed the old belt.
6. Replace the drive belt, according to directions on prior
page.
7. Install the hydraulic drive belt onto the two pulleys.
8. Tighten the nuts on the adjusting bolt to move the pump
mounting bracket. Stop when the belt is at the desired
tension.
9. Tighten the mounting bolts on the pump mounting bracket
to the proper torque.
10. Check pulleys for proper alignment and adjust if neces-
sary.
