Vane pump, reservoir, hydraulic lines on petrol engines: Assembly overview
The hydraulic pump may not be repaired. If there are complaints, the cause of error must be determined through pressure and leakage tests. If there is any fault, the hydraulic pump must be replaced.
The oil circuit on RH drive vehicles corresponds to the circuit on LH drive vehicles, with the exception of forwarding the hydraulic lines from left to right on the steering drive.
  Note
t  Always check steering system for leaks if fluid level in reservoir is low.
t  If there are leakages in the connection area of the lines, the tightness of the lines/ connections must be checked first. Tighten them if necessary and wipe with a piece of cloth.
t  The pumps supplied as spares contain no oil. For this purpose, always fill with CHF 202 hydraulic oil before installing: Assignment → Spare parts catalogue and turn by hand otherwise noises can occur while driving or the pump can be damaged.
t  Oil type: Hydraulic oil CHF 202: Allocation → Spare parts catalogue.
