REMOVAL & INSTALLATION
See Figure 1
Some pumps will have a quick-connect fitting for the pressure line. This fitting may, under certain circumstances, leak and/or be improperly engaged resulting in unplanned disconnection.
The leak is usually caused by a cut O-ring, imperfections in the outlet fitting inside diameter, or an improperly machined O-ring groove.
Improper engagement can be caused by an improperly machined tube end, tube nut, snapring, outlet fitting or gear port.
If a leak occurs, the O-ring should be replaced with new O-rings. Special O-rings are made for quick-disconnect fittings. Standard O-rings should never be used in their place. If the new O-rings do not solve the leak problem, replace the outlet fitting. If that doesn't work, replace the pressure line.
Improper engagement due to a missing or bent snapring, or improperly machined tube nut, may be corrected with a Ford snapring kit made for the purpose. If that doesn't work, replace the pressure hose.
When tightening a quick-connect tube nut, always use a tube nut wrench; never use an open-end wrench! Use of an open-end wrench will result in deformation of the nut! Tighten quick-connect tube nuts to 15 ft. lbs. maximum.
Swivel and/or endplay of quick-connect fittings is normal.1990-90 Models
If a leak occurs between the tubing and the tube nut, replace the hose assembly. If a leak occurs between the tube nut and the pump outlet outlet replace the plastic washer.
- Check the fitting to determine whether the leak is between the tube and tube nut or between the tube nut and pump outlet.
- If the leak is between the tube nut and pump outlet check to be sure the nut is tightened to 30-40 ft. lbs. Do not overtighten this nut.
- If the leak continues or if the leak is between the tube and tube nut, remove the line.
- Unscrew the tube nut and inspect the plastic seal washer. Replace the plastic seal washer when the line is removed.
- To aid in the assembly of the new plastic seal washer, a tapered shaft may be required to stretch the washer so that it may be slipped over the tube nut threads.
- If the rubber O-ring is damaged it cannot be serviced and the hose assembly will have to be replaced.
- Connect the tube nut and torque to 30-40 ft. lbs.
