Steering System, Checking For Leaks

Steering System, Checking for Leaks

• Following repair procedures and with no hydraulic fluid in the reservoir, the steering system must be checked for leaks.

- Start the engine.

- Turn the steering wheel in both directions to full lock and hold briefly.

This builds up the maximum possible pressure.

• To avoid damage to the pump, the steering wheel must not be held at the lock longer than 10 seconds during this test.

In this position, the following components must be checked for leaks.

• Seal ring for the steering pinion at the steering gear valve housing.

• All line connections.

• Seal rings for the steering rack.

This test can only be performed with the boots slid back.

- Open the boot spring hose clamp and ear hose clamp.

- Slide the boot back.

If fluid is visible in the steering gear housing and/or in the boots, the steering gear must be replaced.
