General Maintenance
5.3 UHP Pump & Vacuum
Blower Drive Belts
The primary drive belts that connect the OMSI
Drive PTO to the UHP pump and vacuum blower
are special 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
OVERTIGHTENED 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.
Periodic Maintenance:
• Check drive belt tension, pulleys and belt align -
ment monthly. Adjust or replace as required.
• Check and grease pillow drive pulley pillow
block bearings.
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 recommended.
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.

(The belts on your truck may be slightly different)
Checking belt tension using a sonic tension
meter:
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” (.6mm) away from the back of
the belt. The Sonic Tension Meter will display the
static tension vibration frequency.
If the frequency is lower than the minimum recom-
mended frequency, the belt should be tightened.
If it is higher than the maximum recommended
frequency the belt should be loosened.
Note:
The procedure in this example is for the
Gates Sonic Tension Meter shown. Sonic
meters from different manufacturers will
require procedures unique those meters.
