Steer Sensors
he steer sensor measures steer angle and
communicates that information to the ground
controls ECM. The steer sensor on the ground
controls side of the machine at the square end acts
as the lead sensor. The other three sensors follow
the position, or steer angle, of the lead sensor.
There is a steer sensor mounted to the top of each
upper yoke pivot pin.
Note: If the square-end steering function becomes
inoperative, switch to circle-end steer mode and the
ground controls side circle-end steer sensor will
become the lead sensor.
Note: This procedure will require a minimum of two
people.

4
Measure the distance between the inside of
one circle-end tire and the chassis side plate
on both sides of the axle.
Result: Both measurements should be the
same to indicate that the tires are parallel with
the chassis.
Square-end
Measure here
Note: If the measurements are different or if a tire is
not parallel with the chassis, the steer sensor of that
tire will need to be adjusted. Refer to Repair
Procedure, How to Adjust a Steer Sensor.
