Steering gears with modified gaskets have been used in production, beginning with VIN 81 GA 054 285.
This change is a preparatory measure that will make it possible later to introduce a new vane pump with higher pump pressure.
The replacement part number of the new steering gear is stamped on the identification plate on the rotary valve housing. Use this number when replacing the steering gear.
Note
