CLUTCHES
Engine Braking System (EBS) Operator Guidelines
OPERATION GUIDELINES FOR EBS CLUTCHES
• EBS clutches have a slightly higher starting gear ratio between the drive and
driven clutch due to the location of the one-way clutch on the clutch shaft. For
best performance and belt life, a/ways use low-range in hilly terrain and when
towing or hauling a load. In fact, High Range should only be used
when traveling on level ground with light or no load.
• EBS kits are recommended for models equipped with High / Low / Reverse
transmissions. Engine braking is enhanced when operating in low range-espe-
cially with 2 stroke model ATVs.
• When an operator makes the transition to and from engine braking engagement,
the driven clutch helix changes from the acceleration side to the deceleration
side. An audible engagement noise may be heard during this transition and is a
normal condition.
• Changes to drive clutch calibration are recommended if the vehicle will be oper-
ated at elevations above 3000 ft (900 meters). Refer to the model specific clutch-
ing chart for type of drive clutch weight and/or drive clutch spring to install for
high elevation.rn
A
WARNING
&.
All PVT system maintenance repairs must be performed only by an authorized
Polaris service technician who has attended a Polaris sponsored service training
seminar and understands PVT system maintenance and repair procedures.
Because of the critical nature and precise balance of components within the
PVT system, it is absolutely essential that no attempt at disassembly or repair
be made without factory authorized special tools and service procedures.
• Refer to your Owner's Safety and Maintenance Manual for system maintenance
intervals.
rn Disregard references to the driven clutch helix position. Helix adjustments do not
apply to the EBS driven clutch.
