Pressure and Return Line Fitting

Tools Required:

• Teflon Seal Installer D90P-3517-A2, A3

Seal Replacement

If a leak occurs between the tubing and the tube nut or is at O-ring, replace the hose assembly. If a leak occurs between the tube nut and the aluminum gear housing, replace the plastic washer. The following procedure should be used:

1. Remove the steering gear mounting bolts, and lower the gear to gain access to the fittings.

2. Check the fittings to determine which fitting is leaking and whether the leak is between the tube and tube nut or between tube nut and gear housing.

3. Check to make sure that the nuts are tightened to 27-34 Nm (20-25 lb-ft). Do not over-tighten.

4. Unscrew the tube nut, and inspect the plastic seal washer. Replace if required. To facilitate assembly of the new TFE seal, a tapered shaft such as Teflon Seal Installer D90P-3517-A2, A3 or equivalent may be required to stretch the washer, so it may be slipped over the tube nut threads.
