Pvt Overheating / Diagnosis - Polaris RZR XP 1000 2014 Service Manual

PVT 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.
Using High gear for heavy loads, hilly terrain, sand/dune environments, or in wet, muddy conditions will increase the

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.
NOTE
chance of drive belt damage.
