CLUTCHING
4.11
Helix Angles and Effects (Polaris Clutch)
The driven clutch helix was selected for overall performance in relation to the other driven system components. In
fine tuning situations requiring a slight adjustment of engine operating RPM or improved backshift, we
recommend trying a helix change before changing other components.
The helix spring should always be adjusted within its limits before a helix change is performed. The normal rate of
change between helix angle steps is 250 RPM under full throttle. This is approximately the same result as in going
from the No. 1 to No. 4 spring position. NOTE: Increasing spring tension increases engine RPM. RPM changes
may not be evident if other drive or driven clutch components are substandard.
On most models the production helix spring hole location is No. 2. Tension the spring 1/3 turn. Install helix key,
thrust washer and snap ring.
Polaris has several helix angles available for the driven clutch. Refer to the chart below for specific angle effects
and identification. See NOTE: below.

* NOTE: All R-Series, Mod(M), T1, and 40-36 helix ramps are cut 0.060s deeper in the snap ring pocket.
These are made so the driven clutch can open far enough for full shift out with wide 1 7/16s belts.
If these helix ramps are used with narrow belts, 2 additional .030s /.8 mm (PN 7556804) washers (for a total of
three) must be installed under the snap ring to prevent the belt from touching the inner hub at full shift which can
cause belt failure.
Wide belt models use only the existing washer under the snap ring.
NOTE: Always Install Snap Ring with
Chamfer Towards Helix (sharp edge out-
ward)
