Spring Free Length

Measure the drive and driven spring free length with the spring
resting on a flat surface. Replace spring if out of specification.

In addition to proper free length, the spring coils should be
parallel to one another when placed on a flat surface. Distortion
of the spring indicates stress fatigue. Replacement is required.

Drive Clutch Weights

CAUTION

Never shim a drive clutch spring to increase its compression

rate. This may result in complete stacking of the coils and

subsequent clutch cover failure

Team Ramp Angles

The angles and length of the transition between the first and final
angle is stamped on the back of the helix. The first number (A)
designates the starting angle of the ramp. The second number
(B) designates the finish angle. The last number (C) is the
transition distance (in inches) between the starting and finish
angles.

Drive Belts

*Belt dimensions are given in nominal dimensions. There is a +/
- variance for all critical dimensions. Clutch set up must be
inspected when a new belt is installed and, if necessary adjusted.

The drive belt is an important component of the converter
system. In order to achieve maximum efficiency from the
converter, drive belt tension (deflection), clutch offset, and
alignment must be adjusted properly.

Belt Inspection

Measure the belt width and replace it if it is worn severely.
Generally a belt should be replaced if the clutches can no
longer be adjusted to provide the proper belt deflection.

• Project the side profiles and measure from corner to

corner.

• Place a straight edge on each side of the drive belt and

measure the distance where the straight edges intersect
at the top (A,B).

Inspect the belt for loose cords. missing cogs, cracks,
abrasions, thin spots or excessive wear spots. Replace if
necessary.

Inspect the belt for hour glassing (extreme circular wear in
at least one spot an on both sides of the belt). Hour glassing

occurs when the drive train does not move and the drive
clutch engages the belt. Example would be taking off while
the track is frozen to the ground. Remember to always
warm up the track and free it from the ground.

Drive Clutch Bolt Torque

Follow the torque table below when installing the drive clutch.
