4. Unscrew tube nut and inspect plastic seal washer. Always replace plastic seal washer 388898 when return line is removed or seal 38897 when
pressure line is removed. To facilitate assembly of new plastic seal washer, a tapered shaft such as a Teflon Seal Replacer Set 211-D027 or
equivalent may be required to stretch washer, so it may be slipped over tube nut threads.
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 34-46 Nm (25-33 ft. lbs.).
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.
