B3000 4WD V6-3.0L OHV (1995)
Fig. 23 Installing Piston On Worm Shaft
1. Apply suitable power steering fluid to valve sleeve rings, then install worm and valve in housing.
2. Install race nut in housing and torque to 55 - 90 ft.lb.
3. Install race nut setscrew and torque to 15 - 25 in.lb.
4. Place piston on bench with ball guide holes facing up. Insert worm shaft into piston so that first groove is in alignment with hole nearest to center
of piston, Fig. 23.
5. Place ball guide into piston. Place 27 to 29 balls in guide, (depending on piston design), turning worm clockwise (viewed from input end of shaft).
If all balls have not been fed into guide upon reaching right stop, rotate input shaft in one direction and then in the other while installing remaining
balls. After balls have been installed, do not rotate input shaft or piston more than 3 1/2 turns off the right stop to prevent balls from falling out of
circuit.
6. Secure guides to ball nut with clamp. Torque clamp screws to 42-70 inch lbs.
7. Position new lube passage O-ring in counterbore of gear housing.
8. Apply petroleum jelly to teflon seal.
9. Place a new O-ring on valve housing.
10. Slide piston and valve into gear housing, being careful not to damage teflon seal.
11. Align lube passage in valve housing with one in gear housing, and install but do not tighten attaching bolts at this time.
12. Rotate ball nut so that teeth are in same plane as sector teeth. Torque four valve housing attaching bolts to 30 - 45 ft.lb.
13. Position sector shaft cover O-ring in gear housing. Turn input shaft as required to center piston.
14. Apply petroleum jelly to sector shaft journal, then position sector shaft and cover into gear housing. Install brake line bracket, identification tag
and air conditioner line mounting bracket (if so equipped) and sector shaft cover bolts, torquing them to 55 - 70 ft.lb.
15. Attach an inch lb. torque wrench to input shaft and adjust mesh load as outlined previously.
