CHECKS AND INSPECTIONS

CAUTION: The power steering pump, like the steering box must not be disassembled for any reason whatsoever. They are to be sent to the Manufacturer for overhauling.

Check the steering wheel rolling torque with the car stationary and the engine running. The torque must be between 0.6 daN with the engine at idle speed and 0.75 daN with the engine at top rpm: if these values are exceeded check the pressure of the system with the wheels steered completely. To do this insert a pressure gauge using an appropriate Tee union on the pressurised oil delivery pipe to the power steering leading from the pump, and steer completely to one side. Forcing the steering wheel to turn further, the pressure reading should rise to appr. 85 bar. If this fails to occur there is an operating fault in the pump or in the distributor valve of the power steering box.
