Steering Gear: Reassembly
- Install needle bearings with longer edge of outer race facing outward. Ensure top end aligns with housing end surface.
- Install lower bearing so it is positioned .93" (23.6 mm) away from housing inner end surface on Land Cruiser, or .76" (19.4 mm) on all others.
- Install "O" ring and Teflon ring to power piston. Install large and small "O" rings to gear housing. Install power piston assembly to housing. Tighten bolts.
- To adjust worm shaft preload, loosen lock nut. Place adjusting wrench to adjusting plug. Install torque wrench to worm shaft. Tighten adjusting plug to obtain 3.5-5.6 INCH lbs. (.4-.6 N.m) preload. While holding adjusting plug, tighten lock nut.
- Wrap tape around splined area of sector shaft. Align sector shaft teeth with power piston teeth in the centered position. Insert sector shaft into gear housing. Do not turn sector shaft during installation, as damage to "O" ring could result.
- Install sector shaft cover, with seal, to sector shaft adjusting screw. Turn screw counterclockwise until cover will fit completely down on gear housing. Install and tighten bolts.
- To adjust total preload of steering gear, place steering gear in center position. Attach torque wrench to worm shaft. Turn sector shaft adjusting screw until correct total preload is obtained.
- Total preload should be the sum of worm bearing preload plus 1.7-2.6 INCH lbs. (.2-.3 N.m). Install and tighten sector shaft adjusting lock nut.
