Maintenance
Track Tension
Track tension is critical for maintaining correct suspension
operation. If the track tension is too loose, the track may
bunch-up at the rail tips, or slip (ratchet). If the track is too
tight, premature rail slide wear, reduced top speed, rear
suspension vibration can occur.
1. Lift the rear of the machine using a dedicated sled lift.
NOTE: A conventional track stand will not work for
a
djusting track tension on PRO-RIDE Progressive
suspensions as lifting the sled at the bumper will
compress the rear crank and tighten the track.
2. Start the engine and slowly let the engine turn the
tra
ck over.
3. Shut off the engine.
4. Place a 10 lb. (4.54kg) weight at point (A). Point (A)
is 16”
(41cm) ahead of the rear idler shaft (E).
5. Measure the distance between the rail slider and the
tr
ack. The measurement should fall within the
measurement range for the appropriate vehicle.
6. If adjustment is needed, lo
osen the jam nuts (B) on
each rail.
7. Loosen the idler shaft bolts (F).
8. Turn each adjuster screw equally (C) clockwise to
tig
hten track. Turn the adjuster screw equally
counterclockwise to loosen track tension.
9. Torque the jam nuts (B) and idler shaft bolts on each
s
ide to specification.
