The gear is secured to the
sub-frame with 3 bolts and washers which screw into threaded tubes in bushes which are integral with the sub-frame.

The steering gear comprises an aluminum, cast, valve housing which contains the hydraulic valve unit and Servotronic valve.
The mechanical steering rack and the hydraulic actuator are located in a steel cylinder which is attached to the cast valve
housing.

The steering gear uses a rack with an integrated piston which is guided on plain bearings within the cylinder and the valve
housing. The pinion, which is attached to the valve unit, runs in bearings and meshes with the rack teeth. The rack is pressed
against the pinion by a spring loaded yoke which ensures that the teeth mesh with the minimum of play. The pinion is
connected to the valve unit via a torsion bar. The rotary motion of the steering wheel is converted into linear movement of the
rack by the rack and pinion mechanism and is initiated by the valve unit. This movement is transferred into movement of the
road wheels by adjustable tie-rods.

The reservoir is attached to a bracket via 2 rubber mounts, and the bracket is attached to the suspension housing.

The reservoir is a plastic moulding with an integral 80 micron, non-serviceable filter. Two moulded ports at the base of the
reservoir provide for attachment of the fluid supply hose to the power steering pump and fluid return hose from the fluid cooler.
The reservoir is fitted with a removable cap which is screwed 1/4 turn to lock into the reservoir body.
The reservoir has upper and minimum marks moulded on its outside of the body. Fluid Reservoir

8. CAUTION: Air tools MUST NOT be used on steering
column bolts.

Disconnect the lower steering column from the steering
gear.
Remove and discard the bolt.









9. Release the power steering line support bracket.

10. CAUTIONS:


Before disconnecting or removing the components,
make sure the area around the joint faces and connections
are clean and dry. Plug open connections to prevent
contamination.


Cap the power steering line to prevent loses of fluid
and dirt ingress.


If power steering fluid is spilt on the paintwork, the
effected area must be immediately washed down with cold
water. Failure to follow this instruction may result in
damage to the vehicle.


NOTE: Some fluid spillage is inevitable during this
operation.

Disconnect the power steering feed and return fluid lines
from the steering gear.
Remove the bolt.
Position a container to collect spillage.
Remove and discard both O-ring seals.

11. Remove the steering gear.
Remove the 3 bolts.
