Assembly

1. Mount the valve hosing in the bench mounted holding fixture, Tool T57L-5O0-B, with the flanged end up.
2. Apply a light coat of Premium Power Steering Fluid, E6AZ-19582-AA (ESW-M2C33-F) or equivalent to the Teflon rings on the valve sleeve.
3. Carefully install the worm shaft and valve in the housing.
4. Install the worm bearing race nut in the housing and tighten to 75 - 122 N.m (55 - 90 ft. lbs.).
5. Install the Allen head race nut set screw through the valve housing and tighten to specification 1.7 - 2.8 N.m (15 - 25 in. lbs.).

Fig. 3 Installing Piston On Worm Shaft:

6. Place the power cylinder piston on the bench with the bell guide holes facing up. Insert the worm shaft into the piston so that the first groove is in line with the hole nearest the center of the piston.
7. Place the ball guides in the piston. Turning the worm shaft counterclockwise as viewed from the input end of the shaft, place the same balls as removed in Step 9 of Steering Gear Disassembly in the ball guide. During assembly 27 to 29 balls are required. If all the balls have not been inserted upon reaching the left stop, rotate the input shaft 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 4.8 - 7.9 N.m (42 - 70 in. lbs.).
9. Apply petroleum jelly or equivalent to the Teflon seal on the piston.
10. Place a new control valve O-ring on the valve housing.
11. Slide the piston and valve into the gear housing being careful not to damage the piston ring.
12. Align the oil passage in the valve housing with the passage in the gear housing. Places new O-ring onto the oil passage hole of the 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 ball nut so that the teeth are in the same plane as the sector teeth. Tighten the valve housing attaching bolts to 41 - 62 N.m (30 - 45 ft. lbs.).
14. Position the sector shaft cover O-ring in the steering gear housing. Turn the input shaft to center the piston.
15. Apply petroleum jelly or equivalent to the sector shaft journal, and position the sector shaft and cover assembly in the gear housing. Install the sector shaft cover attaching bolts. Tighten the bolts to 75 - 94 N.m (55 - 70 ft. lbs.).
16. Attach an in. lb. torque wrench to the input shaft. Adjust meshload to specification. Refer to specifications.Meshload
