Leak at Steering Rack Connection
If you encounter leakage at the steering rack connection in the above models, the cause may be damage to the sealing ring of the hydraulic lines. In such instances, replacement of the rack will not resolve the situation. To resolve, replace the sealing ring at the steering gear connection as per the below procedure.
1. Loosen line connection on steering gear.
Note:
If necessary, loosen line supporting bracket.
2. Replace sealing rings and support ring.
Note:
Ensure that sealing rings and supporting ring are properly seated. Supporting ring only present on high pressure line (not on model 230 and 203 up to 03/02).
Note:
There are two versions of power steering high-pressure lines. The preceding version has a slotted support ring which can be replaced individually. The new version has a support ring which is not slotted and which cannot be replaced individually; in this case the complete power steering high-pressure line must be replaced (see parts list).
3. Fasten line connection on steering gear with retaining plate.
Note:
Observe below torque values for screw connection.
4. Bolt, oil line clamping plate to rack-and-pinion steering
a. Models 203, 211.082/083/087/282/283/287 - 20 Nm
Models 171, 209, 211 except 211/082/083/087/282/283/287 - 18 Nm
b. Bolt on Clamp Plate, high-pressure line / return line to rack-and-pinion steering
Model 230 - 18 Nm
5. Bleed steering system and check for leaks. Refer to the WIS documents shown for bleeding the system / checking for leaks.
