Disassemble
Support Base
The support base may be disassembled to access the steer
swivel bearings, the steering gear, or the torque sensor.
1.
Remove the steer support assembly as a unit if neces-
sary to access the support base. See Remove (Com-
plete Unit) in this section. Move the assembly onto a
clean workstation and securely support in position for
disassembly.
2.
Remove the two screws and washers securing the gear
cover and remove. See Figure 18. Lift the pinion from
the support base. Repair or replace as necessary. Refer
to Articulating Shaft and Pinions (EPAS).
3.
Remove two capscrews and washers from the bottom
of the support base. See Figure 19. Lower the support
base from the center support.
4.
Remove the snap ring and bearing from the support
base using an appropriate-sized driver.
5.
Remove the pin from the bottom of the steer gear and
lower the gear from the torsion shaft. See Figure 20.
NOTE:
Make note of torque sensor position and orienta-
tion.
6.
Recover the torque sensor from the swivel.
7.
Check that sensor guard is securely mounted to the un-
derside of the center support and properly engages
with the sensor to prevent rotation. Repair or replace as
necessary. See Figure 21.
