CVT OVERHEATING/DIAGNOSIS
During routine maintenance 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
Heavy loading, basic operational speeds less than 10Km,
riding through rough terrain (swamps, mountains, etc.),
low ground speeds.
High ground speeds, speeds above 30Km.
Diagnosis of Clutch Drive Belt & Cover Related Issues:
Possible Causes
Solutions/What to do?
Heaving Loading onto the scooter when in high
range.
Drive to low speed during loading of the scooter to
prevent belt burning.
Starting out going up a steep incline.
When starting out on an incline, applying the brake and
perform the “K” turn.
Driving at low RPM or low ground speed
(At approximately 5--12 km).
Drive at higher speed for cooler CVT operating
temperatures and longer component life.
Insufficient warm--up of 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.
Stuck in mud or snow.
Reduce to Low RPM, carefully use fast, aggressive
throttle application to engage clutch.
Warning: Excessive throttle may cause loss of
control and scooter overturn.
Belt slippage from water or snow ingestion into the
CVT system.
Let engine keep in idle speed. Using the throttle, vary the
engine rpm from idle to 3/4 throttle openings 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.
A certified AEON technician should perform
Inspection/repair of clutch components.
