EPS motor & gearbox
The steering input passes through the torsion coupling
and module into the gearbox. The gearbox then passes
the input force to the output shaft connected to the steer-
ing housing.
The EPS motor assists in turning the input shaft by
driving a set of planetary gears. The planetary gears drive
a worm shaft. The worm shaft drives a worm gear on the
output shaft.
IMPORTANT: DO NOT open or service the steering
gearbox.
DO NOT drop or hammer on any of
! CAUTION ! CAUTION
the EPS components.
There is a torque senor that is
trapped between the torsion coupling and the
EPS module. If this sensor shifts, it can cause an
auto-steer condition.
