Assembly

1. NOTE: Failure to use proper seal installation tools and procedures may damage the seals and cause a fluid leak.

   Mount the worm end of the power steering gear input shaft and control (3D517) assembly into a soft-jawed vise.

2. Install Mandrel T75L-3517-A1 from the Seal Replacement Set T75L-3517-A over the sleeve; slide one valve sleeve seal over the tool.

   
   
   
   
   

3. Slide Pusher T75L-3517-A2 over the mandrel; rapidly push down on the pusher tool, forcing the seal down the ramp and into the fourth groove of the valve sleeve. Repeat this step three more times and each time add one Spacer T75L-3517-A3, under the mandrel tool. By adding the spacer each time, the mandrel tool will line up with the next groove of the valve sleeve.

   
   
   
   
   
   
   
   
   

4. After installing the four valve sleeve seals, apply a light coat of Premium Power Steering Fluid E6AZ-19582-AA or equivalent meeting Ford specification ESW-M2C33-F to the sleeve and seals.

5. Install one Spacer T75L-3517-A3 over the power steering gear input shaft and control as a pilot for installing the sizing tube. Slowly install the sizing tube Tool T75L-3517-A4 over the sleeve valve end of the power steering gear input shaft and control onto the valve sleeve seals. Make sure the seals are not being bent over as the tube is slid over them. Allow the sizing tube to sit over the seals for five minutes.

   
   
   
   
   
   
   
   
   

6. Remove the sizing tube and check the condition of the seals. Make sure the seals turn freely in the grooves. No further service or disassembly of the power steering gear input shaft and control is possible. Valve centering will be destroyed if disassembly is attempted.
