Steer Sensors

The 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.
Note: Perform this procedure with the axles
extended.

Axle Components

Measure the circle-end tires:
3 Press the square-end steer mode button.
4 Measure the distance between the inside of
one circle-end tire and the chassis side plate on
both sides of the axle.
Square-end
Result: Both measurements should be the
same to indicate that the tires are parallel with
the chassis.
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. See How to
Adjust a Steer Sensor.
5 Repeat step 4 for the other circle-end tire.
