DESCRIPTION:
The procedure for removal and replacement of the oil pipes on the steering gear (rack) is missing in VIDA. These are not the power steering pressure and return hoses that route power steering fluid to and from the power steering pump/reservoir. These are the metal pipes on the steering gear itself. Also, a new clip has been implemented into production after chassis limits listed above to hold the pipes to the steering gear.

MATERIALS:





TOOLS:





SERVICE:
The oil pipes can be replaced according to the following instructions. A new clip comes with the pipes as part of a "pipe kit" (found in VIDA parts catalog).

Preparations
Remove the steering gear according to VIDA:
- Removing, replacing and installing
- Suspension, steering
- Steering gear
- Steering gear, replacement

Note! Seal the intake and exhaust connections from the servo pump with plastic plugs immediately after removal.

Replacing the oil pipes





Remove the protective plate from over the pipes.
Seal the intake and exhaust connections using plastic plugs.
Carefully clean around the oil pipe connections and blow dry.
Remove the pipes.





Carefully check that there is no residue of the old sealing rings in the connections on the steering gear.





Install the new sealing rings on the oil pipes. Lubricate the sealing rings using servo oil 30741424 (1 litre).





Carefully install the new pipes with the sealing rings to the steering gear.

Note! Use a new screw for the pipe's holder.

Tighten the pipe nuts to 7 Nm (5.2 ft. lbs. or 62 in. lbs.) and the holder screw to 12 Nm (8.9 ft. lbs. or 106.2 in. lbs).

Install the protective panel over the pipes.

Install the support clip for the oil pipe





A support must be positioned on the longer of the two oil pipes as illustrated.
MAX 132 mm (5.2")
MIN 110 mm (4.3")

Note! Only one support must be used, the illustrations show the support in its relevant outer positions.

Install the steering gear
Install the steering gear in reverse order.

Note! Checking and adjusting Toe-in must not be carried out since no adjustable joints have been loosened.
