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.
CLUTCH DRIVE BELT & COVER RELATED ISSUES: DIAGNOSIS
POSSIBLE CAUSES
Loading the vehicle into a tall trailer
when in high range.
Starting out going up a steep incline
from a stopped position.
Driving at low RPM or low ground
speed (at approximately 3-7 MPH).
Insufficient engine warm-up when
exposed to low ambient temperatures.
Slow and easy clutch engagement.
Stuck in mud or snow.
Climbing over large objects from a
stopped position.
Belt slippage from water or snow
ingestion into the PVT system.
Clutch malfunction.
Poor engine performance.
GENERAL RANGE OPERATION
GUIDELINES:
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. Note: Do not shift from Low to High without coming to a complete stop.
NOTE: Using High gear for heavy loads, hilly terrain, sand/dune environments, or in wet, muddy conditions
will increase the chance of drive belt burning.

SOLUTIONS / WHAT TO DO
Shift transmission to Low during loading of the vehicle to prevent belt
burning.
When starting out on an incline, use Low gear. Shift transmission to Low
during loading of the vehicle to prevent belt burning.
Drive at higher speed or use Low. The use of Low is highly recommended
for cooler PVT operating temperatures and longer component life.
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.
Fast, effective use of the throttle for efficient engagement.
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.
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.
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 component inspection should be performed by a Polaris MSD
certified technician.
Fouled spark plugs, foreign material in fuel tank, restricted fuel lines, or
faulty fuel pump may cause symptoms similar to clutching malfunction.
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.
