| Checking the power steering system for leaks |
Note | t
| If metal swarf is found in the hydraulic oil and/or in the reservoir, the reservoir as well as the suction and pressure lines must be cleaned very carefully and if necessary replaced. |
| t
| Check the power steering system for tightness after assembly work and in the event of hydraulic oil loss in the reservoir. |
| –
| Turn the steering wheel in both directions up to the end stop and hold for a short while. |
| This will build up the highest possible pressure. |
| –
| Check all line and hose connections for correct position and tightness. |
| –
| In the event of leaks tighten the line or hose connections to the allowed tightening torques or replace the seal or line. |
| –
| Check hoses and lines for leaktightness. If there are leaks replace the relevant hose or line. |
| –
| Check vane pump for tightness. If there are leaks, replace the vane pump. |
| –
| Check the hydraulic oil reservoir for tightness. If there are leaks, replace the reservoir. |
| –
| Check the level of hydraulic oil, if necessary top up with oil → Chapter. |
Note | If there is a repeated loss of hydraulic oil from the reservoir and if the hoses and lines as well as their connections, the vane pump and the reservoir have been thoroughly inspected repeatedly, remove and inspect the power-assisted steering gear. |
