PVT SYSTEM OVERHEATING / DIAGNOSIS
During routine maintenance, or whenever PVT system
overheating is evident, it’s important to check the inlet
and
outlet duct for obstructions. Obstructions to air flow
through the ducts will significantly increase PVT system
operating temperatures. The vehicle should be operated
in Low when extended low vehicle speed operation is
anticipated.

ISSUES: DIAGNOSIS
POSSIBLE
CAUSES
SOLUTIONS / WHAT TO DO
Loading the
vehicle into a tall
trailer when in
high range.
Shift transmission to Low during
loading of the vehicle to prevent
belt burning.
Starting out going
up a steep incline
from a stopped
position.
When starting out on an incline,
use Low gear. Shift transmission
to Low during loading of the
vehicle to prevent belt burning.
Driving at low
RPM or low
ground speed (at
approximately 3-
7 MPH).
Drive at higher speed or use Low.
The use of Low is highly
recommended for cooler PVT
operating temperatures and
longer component life.
Insufficient
engine warm-up
when exposed to
low ambient
temperatures.
Warm engine at least 5 min., then
with transmission in neutral,
advance throttle to approx. 1/8
throttle in short bursts, 5 to 7
times. The belt will become more
flexible and prevent belt burning.
Slow and easy
clutch
engagement.
Fast, effective use of the throttle
for efficient engagement.
Stuck in mud or
snow.
Shift the transmission to Low,
carefully use fast, aggressive
throttle application to engage
clutch.
WARNING:
Excessive
throttle may cause loss of control
and vehicle overturn.
Climbing over
large objects from
a stopped
position.
Shift the transmission to Low,
carefully use fast, aggressive,
brief throttle application to engage
clutch.
WARNING:
Excessive
throttle may cause loss of control
and vehicle overturn.
Belt slippage
from water or
snow ingestion
into the PVT
system.
Remove the PVT drain plug. Shift
the transmission to neutral. Using
the throttle, vary the engine rpm
from idle to full throttle. Repeat
several times as required. During
this procedure, the throttle should

not be held at the full position for
more than 10 seconds. Clutch
seals should be inspected for
damage if repeated leaking
occurs.
Clutch
malfunction.
Clutch component inspection
should be performed by a Polaris
MSD certified technician.
Poor engine
performance.
Fouled spark plugs, foreign
material in fuel tank, restricted fuel
lines, or faulty fuel pump may
cause symptoms similar to
clutching malfunction.
GENERAL
RANGE
OPERATION
GUIDELINES:
Low:
Basic operational speeds
less than 7 MPH, riding through
rough terrain (swamps,
mountains, ect.), or low ground
speeds and when continuously
operating at speeds less than 30
mph in sand/dune environments.
High:
High ground speeds, or
speeds above 7 MPH.
Operating in Low Gear
Low gear should be used when riding through rough
terrain or when basic operational ground speeds are less
than 7 MPH. Use High gear when basic operational
ground speeds are more than 7 MPH.
General Sand / Dune Driving
The use of Low gear when continuously operating at
speeds less than 30 mph will greatly increase belt life in
sand/dune environments.
NOTICE
Do not shift from Low to High without coming to a
complete stop.
Using High gear for heavy loads, hilly terrain, sand/
dune environments, or in wet, muddy conditions will
increase the chance of drive belt burning.
