CVT SYSTEM
CVT OVERHEATING/DIAGNOSIS
During routinemaintenance or whenever CVT 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 CVT system operating temperatures. The ATV
should be operated in LOW RANGE (if equipped) when pulling or plowing heavy loads, or if extended low speed operation is
anticipated.
GENERAL RANGE OPERATION
GUIDELINES:
Low Range (if equipped) : Heavy pulling, basic operational
speeds less than 10Km, riding through rough terrain (swamps,
mountains, etc.), low ground speeds.
High Range : High ground speeds, speeds above 10Km.
Diagnosis of Clutch Drive Belt & Cover Related Issues:
Possible Causes Solutions/What to do
Loading the ATV into a pickup or tall trailer when in high range. Shift transmission to low range (if equipped) during loading of
the ATV to prevent belt burning.
Starting out going up a steep incline. When starting out on an incline, use low range (if equipped), or
dismount the ATV after first applying the park brake and perform
the “K” turn.
Driving at low RPM or low ground speed
(at approximately 3--7 MPH).
Drive at higher speed or use Low Range. (if equipped) The use
of Low Range is highly recommended for cooler CVT operating
temperatures and longer component life.
Insufficient warm--up of ATVs 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.
Continuous operation at the point of engagement (initial vehicle
movement) increases CVT temperatures and component wear.
Towing/Pushing at low RPM/low ground speed. Use Low Range only. (if equipped)
Plowing snow, dirt, etc./utility use. Use Low Range only. (if equipped)
Stuck in mud or snow. Shift the transmission to Low Range (if equipped), 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 Range (if equipped), carefully use
fast, aggressive, 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 CVT system. Shift the transmission to neutral. Using the throttle, vary the
engine rpm from idle to 3/4 throttle . Engage transmission in the
lowest possible range (if equipped) and test for belt slippage.
Repeat several times as required. During this procedure, the
throttle should not be held at the full position . CVT seals
should be inspected for damage if repeated leaking occurs.
Clutch malfunction. Inspection/repair of clutch components should be performed by
a certified Goes MSD techinician.
