Assembly
Coat the fluid inlet and outlet tube seats with petroleum jelly or equivalent. Install seats in the housing with a Brass Tube Seat Replacer T74P-3504-M.
Coat the bearing and seal surface of the steering gear housing (3548) with petroleum jelly or equivalent.
Install the input shaft bearing with the metal side covering the rollers facing outward. Seat the bearing in the valve housing using T65P-3524-A1. Be sure the bearing rotates freely.
Dip a new oil seal in gear lubricant, Premium Power Steering Fluid E6AZ-19582-AA or equivalent meeting Ford specification ESW-M2C33-F and place it in the housing with the metal side facing outward. Drive the seal into the steering gear housing until the outer edge does not quite clear the snap ring groove.
Place the snap ring in the housing and drive on the ring using T65P-3524-A1 until the snap ring seats in its groove.
Place the dust seal in the housing with the dished side (rubber side) facing out. Drive the dust seal into place using T65P-3524-A1. When properly installed, the seal will be located behind the undercut in the power steering gear input shaft and control (3D517).
Apply a generous amount of Ford Multi-Purpose Grease D0AZ-19584-AA or equivalent meeting Ford specification ESB-M1C93-A to the area between the two seals.
