CLUTCHING
POLARIS P-85 HELIX
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 (P-85).
NOTE: Increasing spring tension increases engine RPM. RPM changes may not be evident if other drive or
driven clutch components are substandard.
NOTE: All R-Series, Mod(M), T1, and 40-36 helix ramps are cut 0.060, deeper in the snap ring pocket. These
are made so the driven clutch can open far enough for full shift out with wide 1 7/16, belts.
If these helix ramps are used with narrow belts, 2 (two) additional (for a total of three) .030, /.8 mm washers (PN 7556804) should
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.
