Steering Gear

Take the following precautions when servicing the steering gear (3504) :

1. Use a clean work bench and tools.

2. Thoroughly clean the exterior of the steering gear with solvent. Drain off excess hydraulic fluid.

3. Handle all parts carefully to avoid nicks, burrs, scratches, and dirt.

4. Do not use solvent on seals.

5. Impact tools must not be used during any of the operations.

   The gear housing and valve housing are combined into a one-piece aluminum die casting. The gear design incorporates quick connect fittings for the power steering pressure hose (3A719) and power steering return hose (3A713) that allow the hoses to swivel; this is normal and does not indicate loose fittings. If the fittings leak, check to ensure that they are tightened to 14-20 Nm (10-15 lb-ft). Do not over-tighten. If the leak is not corrected, replace the fitting seals.
