MAINTENANCE
General Maintenance
Variable Exhaust System (V.E.S.)
Maintenance of the V.E.S. is limited to a periodic inspection and
cleaning of system components. Every 1000 to 2000 miles, bring the
machine to an authorized Polaris dealer to have the V.E.S.
disassembled, inspected, and cleaned.
NOTE: To ensure maximum performance and minimize required
maintenance, follow the oil recommendation chart on page
50. The use of other lubricants may cause improper function
of the valve mechanism and increase the frequency of
required cleaning due to excessive build-up of carbon
deposits.
Water Pump Belt Inspection
Liquid cooled RMK and
Switchback models require
inspection of the water
pump belt at 1500 miles
(2400 km). Inspect belt
width (A) and condition,
and replace if cracked or
worn past the width service
limit (.250″ / 6.35mm).
New belt width is
approximately .345″ (8.75
mm). See your Polaris
dealer if the belt needs
replacement.
