Ski Leg Camber - BOMBARDIER 1996 Ski-doo MX Z440 Handbook

SKI LEG CAMBER

The camber angle of the ski legs changes how aggressively the ski runners hook up with the
driving surface. Adding negative camber will have the most effect on handling. This is because the
"weight shift" in a turn is always to the outside of the turn and the negative camber of the ski leg
causes the wear bar to be presented to the driving surface in a more aggressive position. Positive
camber will tuck the wear bar in toward the sled, thereby reducing its traction in a turn.
Camber adjustments do have an effect on the width of the machine. Make certain your camber
adjustments do not push you beyond the overall width limit imposed in most forms of racing.
Camber is the tilting of the ski leg from the vertical. To obtain a negative camber angle, the ski leg
must be tilted inward so that the ski legs are closer together at the top than at the bottom. Positive
camber would tilt the top of the ski leg away from the machine. Camber angle is measured in
degrees from the vertical and must be noted as positive or negative.

1. Ski leg vertical= 0° camber
Most oval racers set the left ski leg at 0° camber and the right at -3° to -5° camber. Trail riders and
drag racers should set both ski legs at 0° camber while a cross-country rider most often sets up
both ski legs with -1° to -3° camber.
Camber angle is measured using an angle finder available from most tool supply stores.
Adjustment is performed by adjusting the length of the upper control arm.
PROCEDURE :
NOTE : Any chassis lowering should be performed before adjusting camber.
o
—Make sure the vehicle is leveled by placing the angle finder on the main horizontal frame
member. "Settle" the suspension so the vehicle is sitting at the normal ride height.
