Blower Drive Belts
The drive belts that connect the auxiliary engine
PTO to the UHP pump and vacuum blower are spe-
cial carbon fiber industrial belts that are designed
for high horsepower applications.
The ribbed drive belts are matched to grooved
pulleys and have very little stretch. Therefore,
they typically don’t need to be adjusted often
and proper belt tension is extremely important
when adjustment is required. The belts are strong
enough to cause severe damage to bearings,
shafts and other components if they are set too
tight. Additionally, if a belt is too loose, it can ride
on top of the grooves in the pulleys and become
too tight.
Make sure you follow the instructions and set the
tension to proper specifications when adjusting
the drive belts. Never overtighten them.
WARNING
DRIVE BELTS CAN CAUSE SEVERE DAMAGE TO PULLEYS,
SHAFTS AND BEARINGS IF THEY ARE ADJUSTED TOO TIGHT
OR MISALIGNED. ALWAYS MAKE SURE THE BELTS ARE
PROPERLY ALIGNED AND SET TO THE MANUFACTURES
SPECIFICATIONS WHEN THEY REQUIRE ADJUSTMENT AND
NEVER OVERTIGHTEN THE BELTS.
Drive Belt Inspection and Maintenance
Daily:
• The belts must be inspected before each shift
for damage, tension and alignment.
Monthly/200 Maintenance:
• Check drive belt tension, pulleys and belt align
-
ment. Adjust or replace as required.
Checking Belt Tension
The proper way to check belt tension is to use a
tension tester. While a simple spring scale type
tester will do the job, the more sophisticated sonic
tension meter is highly recommended.
Checking Belt Tension
Sonic Tension Meter Method
The Sonic Tension Meter detects the vibration
frequency in the belt span and converts that mea-
surement into the actual static tension in the belt.
Begin by entering the belt unit weight, belt width,
and the span length. To measure the span vibra-
tion, press the “Measure” button on the meter,
tap the belt span and hold the microphone ap-
proximately 1/4” (.6 mm) away from the back of
