2.15 UHP Pump & Blower Drive Belts
The drive belts that connect the auxiliary engine PTO
to the high pressure 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
require adjustment often and proper belt tension is
extremely important when adjustment is required.
The belts are strong enough to cause severe dam-
age 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 and thus
become too tight.
The drive belts for the high pressure pump and
vacuum blower are different and, therefore, have
different tension specifications. Additionally, new
belts have a different tension specification than
used belts (drive belts with 20 hours or more). In-
structions for adjusting the primary drive belts and
tension specifications are included in the General
Maintenance section of this manual.
WARNING
THE DRIVE BELTS CAN CAUSE SEVERE DAMAGE TO
PULLEYS, SHAFTS AND BEARINGS IF THEY ARE ADJUSTED
TOO TIGHT OR MISALIGNED. THIS CAN CAUSE SEVERE
DAMAGE TO DRIVE SYSTEM COMPONENTS AND INJURY

THROWN FROM THE MACHINE. ALWAYS MAKE SURE THE
BELTS ARE PROPERLY ALIGNED AND SET TO THE BELT
MANUFACTURER’S SPECIFICATIONS WHEN THEY REQUIRE
ADJUSTMENT. NEVER OVERTIGHTEN THE BELTS.
Make sure you refer to the belt tension specifications
in the Maintenance section of this manual or the belt
manufactures information manual when adjusting
the belt tension and never overtighten them.
2.16 Pneumatic System
Compressed air from the truck compressor acti-
vates the pneumatic clutch on the auxiliary engine
PTO, shifts the split shaft in the transfer case to
Creep or Dive modes and is used to inflate the
debris tank door seal.
The PTO clutch is engaged by a two stage, soft
start pneumatic engagement system. The en-
UHP Pump & Blower Drive Belts
gage sequence is fully automatic and initiated
when the CLUTCH switch is turned on. The first
stage is the soft start engagement which limits
pressure to allow for some clutch slippage. The
second stage engages a couple seconds after the
first stage and delivers enough pressure to fully
engage the clutch.
A manual pressure regulator with a gauge controls
air pressure to the first stage. The regulator can
be adjusted to increase or decrease initial clutch
engagement as desired. The second stage regu-
lator air pressure and delay time is preset at the
factory and is not adjustable.
