12. Remove the power steering gear race nut using Adjuster and Lock Nut Wrench T66P-3553-B and Valve Housing to Piston Spacer T66P-3553-C.
13. Carefully slide the power steering gear input shaft and control and steering gear input worm gear and rack out of the valve housing.
Assembly
NOTE:
^
Do not use solvent on seals. Using a clean workbench and tools, thoroughly clean the exterior of the gear with solvent. Drain off excess hydraulic
fluid, if necessary.
^
Handle all parts carefully to avoid nicks, burrs, scratches and dirt.
1. Mount the valve housing in the Bench Mounted Holding Fixture T57L-500-B with the flanged end up.
2. Apply a light coat of MERCON(R) Power Steering Fluid XT-2-QDX or MERCON(R) equivalent to the Teflon rings on the valve sleeve.
3. Carefully install the power steering gear input shaft and control valve in the steering gear housing.
4. Install the power steering gear race nut in the housing, and tighten to 75-122 Nm (55-90 ft. lbs.).
5. Install the Allen head race lock nut setscrew through the valve housing, and tighten to 1.7-2.8 Nm (15-25 inch lbs.).
6. Place the piston on the bench with the ball guide holes facing up. Insert the power steering gear input shaft and control into the piston so the first
groove is in line with the hole nearest the center of the piston.
7. Place the steering gear ball return guide in the piston. Turning the power steering gear input shaft and control counterclockwise, place the same
steering gear worm balls as were removed in the steering gear ball return guide. During assembly, 27 to 29 balls are required. If all the balls have
not been inserted upon reaching the left stop, rotate the power steering gear input shaft and control in one direction then the other while inserting
the remaining balls.
8. Secure the guides in the ball nut with the clamp. Tighten screws to 5-7 Nm (45-61 inch lbs.).
9. Apply petroleum jelly or equivalent to the Teflon seal on the piston.
10. Place a new steering gear sector shaft housing cover gasket on the valve housing.
11. Slide the piston and valve into the steering gear housing, being careful not to damage the piston ring.
12. Align the on passage in the steering gear ball return guide with the passage in the steering gear housing. Place a new O-ring onto the oil passage
hole of the steering gear housing. Install identification tag onto the housing. Install, but do not tighten, the attaching bolts. Identification tag is to
be installed under upper right valve housing bolt.
13. Rotate the piston so the teeth are in the same plane as the steering gear sector shaft. Tighten the valve housing attaching bolts to 40-60 Nm (30-44
ft. lbs.).
14. Position the steering gear sector shaft housing oil seal in the steering gear housing. Turn the input shaft to center the piston.
