The steering position sensor is a two–piece assembly located on top of the rear
wheel caster fork shaft. The sensor portion includes 2 analog hall effect sensors.
The second piece of the assembly is a bolt with a magnetic head threaded into
the caster fork shaft. The steering position sensor follows the rear caster fork
movement.
For steering position sensor testing information; refer to
(page 5–89)
.
1. Align the rear caster fork; refer to
Aligning the Rear Wheel Caster Fork
(page 6–8)
.
Note:
Be careful not to disturb the rear caster fork alignment while adjusting
the steering position sensor.
2. Loosen the jam nut under the magnet bolt.
3. Adjust the magnetic bolt so the slot in the bolt aligns with the flat on the
castor fork shaft (straight toward the rear of the machine) and the gap
between the top of the bolt and the bottom of the sensor is
2.0 to 3.0 mm
(0.08 to 0.12 inch)
.
4. Tighten the jam nut against the caster fork from
20 to 22 N·m (180 to 200
in-lb)
and recheck the gap between the top of the bolt and the bottom of the
sensor. Adjust the gap if necessary.
5. Check the rear caster fork alignment and readjust the sensor if necessary.
6. Calibrate the steering system. Calibrate the steering system – center first,
then calibrate the steering system – range; refer to
System – Center (page 5–91)
and
Calibrating the Steering System – Range
(page 5–91)
