Drive Belt Adjustment
The UHP pump and vacuum blower are on slotted,
adjustable mounts. A single adjusting bolt in the
center of each pump mounting system is used to
adjust the drive belt.
Drive Belt Adjustment Procedure:
1. Loosen the four bolts on the slotted holes on
the mounting plate just enough to allow the
plate to move. Make sure not to loosen them
too much.
2. Use the center bolt to adjust the belt to the
proper specification. Use a sonic tension meter
to achieve proper tension.
3. Check the pulley alignment with a straight
edge against the outside face of the drive
and driven pulleys to make sure the pulleys
are parallel.
IMPORTANT:
Tighten the mount bolts on the slotted holes
and recheck the belt tension and alignment.
Readjust as necessary to achieve correct belt
tension and/or alignment.
4. Tighten the bolts on the slotted holes
5. Start the engine and engage the PTO at idle
speed for 30 seconds.
6. Disengage the PTO and shutdown the engine.
7. Check that the belt is riding on the center of
the pulleys. If it is not centered and riding
hard on either side of the pulleys, the blower
or UHP pump will have to be aligned slightly
using the slotted mounting plate bolts. Repeat
alignment and tension steps until the belt is
set to the proper tension and centered on the
pulleys.
8. Tighten the mounting bolts securely.
