General Inspection

General


Damage to the power steering can be traced to lack of oil in the hydraulic system. Due to the high system pressure in the hydraulic circuit, even minor leaks may cause fluid loss and damage to the power pump.
Grunting noises when turning the steering wheel or foaming in the reservoir are indicative of lack of oil and/or air drawn in. Before topping up the reservoir, however, repair any leaks remaining on the intake side and replace the defective part on the pressure side.

Important Note
The rack-and-pinion steering gear and the power pump must not be repaired or dismantled.
The steering gear is available as a spare part. See spare parts catalogue.

Power Steering Pump Toothed Belt
The pretension of the toothed belt cannot be adjusted.

Checking The Steering System For Leaks (Visual Inspection)
With the engine idling, turn the steering wheel to the stop position and keep it in this position. This causes the maximum possible line pressure to be built up.
Check all line connections for leaks in this position and retighten if required.
Test for approx. 10 sea. If the test is run for a longer time, allow a short break approx. every 10 seconds.
