STEERING ARM ORIENTATION FOR 440 Pro
X Fan, 440 / 600 /700 / 800 Pro X
WARNING
Steering arm orientation is important to ensure proper
steering tie rod end thread engagement and steering
performance. Always mark steering arms and spindles
before removal for reference upon reassembly. When
installing new parts or after steering arm installation, re-
fer to the illustrations and text below. Always verify
proper steering operation after completing adjustments
or repairs.
1. The steering arms on each spindle should be
parallel to slightly inward in relation to each ski.
When correctly
installed (Ill. 1) the centerline of the
ski and centerline of the ski bolt hole in the spindle
will form (approximately) a 90q angle or slightly
greater.
2. If the steering arm is installed incorrectly the
threads of the steering tie rod end will not engage
the tie rod sufficiently, and the angle formed
between ski and ski bolt centerlines is considerably
less than 90q as shown at right.
3. Reinstall torsion bar linkage (where applicable).
Torque attaching bolts to specification.
Carbide to Ski Placement
A good starting point for placement of carbide is 50/50
(50% forward and 50% behind the ski mounting bolt). This
can be varied depending on the aggressiveness of the car-
bide and the strength of the driver. Make sure the leading
edge of the carbide has a small chamfer.
More carbide trailing will cause the machine to track
straighter, but steering effort will increase.
