Pressure Hose Fittings

NOTE: If a leak occurs between the tubing and tube nut, replace the hose assembly. If a leak occurs between the tube nut and the pump outlet, replace the plastic washer.

1. Check fitting to determine whether leak is between tube and tube nut or between tube nut and pump outlet.

CAUTION: DO NOT overtighten. The casting may crack.

2. If leak is between tube nut and pump outlet, check to make sure nut is tightened to specification. If leak continues or if leak is between tube and tube nut, remove line.





4. Unscrew tube nut and inspect plastic seal washer. Always replace plastic seal washer when line is removed. To facilitate assembly of new plastic seal washer, a tapered shaft such as a Teflon Seal Replacer Set D9OP-3517-A or equivalent may be required to stretch washer, so it may be slipped over tube nut threads. Allow five minutes before reinstallation of fitting.
5. The rubber O-ring cannot be serviced with this design. If leak is due to the O-ring replace the hose assembly.
6. Connect tube nut and tighten to specification.
7. The quick connect fitting may disengage if not fully assembled, if the snap ring is missing, or if the tube nut or the hose end is not machined properly.
^ If the fitting disengages, replace the hose assembly.
^ The fitting is fully engaged only when the hose will not pull out.
^ To test for positive engagement, the system should be properly filled, the engine started, and the steering wheel cycled from lock-to-lock.
^ Service hose assemblies have tube nuts, snap rings and O-rings already retained.
