Hose and Line O-Ring at Pump Connection Repair

NOTE: The O-rings that are used on the tube of the power steering fitting should not be used on the quick connect fittings because of dimensional and material differences. If O-ring replacement does not solve the leak problem, replace the female port (pump outlet fitting) first, and then the hose assembly.

Pump Connection Line Fitting:

The quick connect power steering fittings at the pump may leak if the O-ring is cut or damaged, or if the sealing surfaces in the female port or in the O-ring groove on the hose assembly are improperly machined. If a leak occurs, the O-ring should be replaced with quick connect O-ring 388749-S.

CAUTION: If wear is evident around snap ring groove, replace entire hose assembly.

The quick connect fitting at the pump may disengage if the snap ring is damaged or if the tube nut is not properly machined. If disengagement occurs, the tube end may be serviced with a tube nut service kit containing a new tube nut, snap ring, and O-ring.

The service snap ring must be installed with a minimum amount of deformation to the snap ring. After installation, the snap ring must not be distorted or bent, and must rotate freely in the snap ring groove. If the hose assembly still does not engage, replace the hose assembly. The system should be properly filled, Service and Repair

Care must be taken not to over tighten the tube nut. Tighten to 10-15 lb. ft. (14-20 Nm). Swivel and/or end play of the quick connect fittings is normal, and does not indicate an under tightened fitting.
