Operation Guidelines For Ebs Clutches - Polaris Trail Blazer Service Manual

OPERATION GUIDELINES FOR EBS CLUTCHES

EBS clutches have a slightly higher starting gear ratio between the drive and
S
driven clutch due to the location of the one-way clutch on the clutch shaft. For
best performance and belt life, always 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
S
transmissions only. Engine braking is enhanced when operating in low range.
When an operator makes the transition to and from engine braking engagement,
S
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-
S
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.
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.
Disregard references to the driven clutch helix position. Helix adjustments do not
¡
apply to the EBS driven clutch.
