Steering System, Checking For Leaks

Steering System, Checking for Leaks

• Following installation operations and with no hydraulic fluid in the expansion tank, the steering system must be checked for leaks.

- Start engine.

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

This builds up the maximum possible pressure.

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

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

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

• All wiring connections,

• The rack sealing rings.

This test can only be performed with boot slid back.

- Open spring-type hose clamp and boot hose clamp.

- Push the boots back.

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