Power Steering Gear: Reassembly
- Install gear box.
- Apply a thin coat of power steering fluid to the new O-ring (2) and be sure to discard used part, then install o-ring.
- Apply a thin coat of power steering fluid to the new seal ring (1) and be sure to discard used part, then install seal ring.
- Apply a thin coat of power steering fluid to the new O-ring and be sure to discard used part, then install o-ring.
- Install ball-nut and valve housing assembly.
- Always keep the ball screw and valve housing assembly in a horizontal position (avoid holding it vertically), or the rack piston will fall off onto the end of the worm, causing the rack piston to slip out of the worm shaft and ball to fall out.
- Be careful not to drop the O-ring into the valve housing.
- Tighten the valve housing bolts to the specified torque.
Torque: 47 N.m (35 lb ft)
- Install sector shaft.
- Tape the sector shaft serrations to protect the seal ring from damage.
- Align the center tooth of ball-nut with that of the sector shaft.
- Install O-ring.
- Install top cover assembly and tighten the fixing bolts to specified torque.
Torque: 47 N.m (35 lb ft)
- Adjust the backlash between the worm gear and the ball-nut.
- With the worm gear rotating, set it to the straight ahead position.
- Set the worm shaft preload to below 10 kg.cm with the sector shaft adjusting screw.
- Measure the worm shaft preload with the worm gear turned 450° both to the right and to the left. The worm gear preload in these positions should be 0.4-0.6 N.m (4-6 kg.cm) lower than in the straight ahead position.
- Lock the sector shaft adjusting screw with the lock nut.
Lock nut Torque: 41 N.m (30 lb ft)
- Apply a thin coat of power steering fluid to oil seal lip of each part, then use installer J-26508 to install oil seal.
- Install back up ring and position the chamfered face (outer circumference) towards the oil seal.
- Install retaining ring and position the chamfered face (outer circumference) towards the oil seal.
- Install dust cover.
