Drive Belt Adjustment Procedures
Vacuum Blower
The vacuum blower is on adjustable mounts. A
threaded adjusting bolt on the blower mount is
used for adjusting the blower drive belt tension.
Make sure the water blasting system is shutdown
and the truck is in the service position. Then use
the following procedure to adjust the vacuum
blower belt.
1. Loosen the four bolts in the slotted holes on
the mounting plate just enough to allow the
plate to move. Make sure not to loosen them
too much.
2. Loosen the blower mount adjusting bolt jam
nut and rotate the adjusting bolt to adjust the
belt to the proper specification. Use a spring
scale tester or sonic tension meter to achieve
proper tension.
