CLUTCHING

Overheating / Diagnosis

During routine maintenance, or whenever PVT system overheating is evident, it's important to check the inlet and
outlet ducting for obstructions. Obstructions to air flow through the ducts will significantly increase PVT system
operating temperatures. The vehicle should be operated in Low when plowing or pulling heavy loads, or if extended
low speed operation is anticipated.
CLUTCH DRIVE BELT & COVER RELATED ISSUES: DIAGNOSIS
Possible Causes
Loading the vehicle into a truck or 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.
Towing/Pushing at low RPM or low ground speed.
Plowing snow, dirt, etc./utility use.
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 pulling heavy loads, 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.
IMPORTANT: Using High gear for heavy loads, hilly terrain, or in wet, muddy conditions will increase the
chance of drive belt burning.
6.6
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.
Use Low only.
Use Low only.
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.
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: Heavy pulling, basic operational speeds less than 7 MPH, riding through rough terrain
(swamps, mountains, ect.), or low ground speeds.
High: High ground speeds, or speeds above 7 MPH.
