Caution: Do not reuse O-rings, replace them with new ones.
2. Using a hair dryer, heat the Teflon ring to 40° and install it on the rail.
Caution: Do not reuse the Teflon ring, replace it with a new one.
3. Place the special tool on the working side of the rack and adjust the position of the ring. Then squeeze the outer surface of the ring.
4. Install the rack seals.
Caution: Do not reuse seals, replace them with new ones.
(1) To prevent damage to the rack, wrap its flange (approx. 70x100mm) a piece of polyethylene. Install the seal and push it onto the rack, moving it simultaneously with the piece of polyethylene.
(2) Insert the rack into the steering gear housing assembly.
Caution: Do not damage or scratch the inner walls of the housing. Otherwise, oil leaks may occur, which will require replacement of the housing assembly.
(3) Install the centering sleeve onto the rack.
Caution: Do not damage the inner walls of the housing with the rack. Otherwise, oil leaks may occur, which will require replacement of the housing assembly.
(4) Insert the inner oil seal onto the piston section, push the rack into the housing and install it so that the inner oil seal rests against the centering sleeve.
Caution: Do not damage the inner walls of the housing with the rack. Otherwise, oil leaks may occur, which will require replacing the housing assembly.
(5) To prevent damage to the rack, wrap its flange (approx. 70x100mm) a piece of polyethylene. Install the outer seal and push it onto the rack, moving it simultaneously with the piece of polyethylene.
(6) Align the oil seals as shown in the figure.
Using a 36 mm open-end wrench, tighten the plug to the required torque.
Caution: Do not damage the surface of the rack. Otherwise, oil leaks may occur, which will require replacement of the rack.
6. Tighten the cap. Then, caulk the body as shown in the figure to prevent loosening.
7. Install adjusting washers and O-rings into the housing.
Caution: Do not reuse the adjusting washers, replace them with new ones.
8. Install the steering gear assembly onto the housing.
9. Install the locking plate on the rack.
(1) Place the spacer on the rack.
Caution: Do not reuse the spacer, replace it with a new one.
(2) Install the lock plate onto the inner tip.
Caution: Do not reuse the lock plate, replace it with a new one.
(3) Apply the fixing compound (Three Bond 1324) onto the thread of the inner tip, screw it into the rack and tighten it to the required torque.
(4) Clamp the locking plate into the grooves on the rack in two places.
(5) Fix the spacer to the lock plate as shown in the figure.
Caution: Be careful not to damage the spacer.
10. Determine the neutral position of the rack.
- Rack travel "L": 66.0 mm
11. Install the cap as shown in the figure.
12. Install the tubes onto the body.
13. Install the holder and spring into the housing.
14. Apply Three Bond TB1111B to the threads of the adjusting screw and screw it in.
15. Tighten the lock nut by hand without tightening it.
16. Tighten the adjusting screw to 4.9-5.8 Nm (0.5-0.6 kg·m), then tighten it another 0.2 Nm (0.02 kg·m).
17. Rotate the gear completely 10 times.
18. Using special tools, measure the rack turning force within ±180°. Stop at the point of greatest force.
19. Loosen the adjusting screw. Then tighten it to 4.9 Nm (0.5 kg·m) and turn it another 60-80°;
20. Fix the adjusting screw so that it does not turn and tighten the lock nut with a force of 40-58 Nm (4.0-6.0 kg·m)
21. Install the indicator as shown in the figure. Turn the pinion with a force of 20 Nm (0.2 kg·m), measure the rack play and make sure that it is within the standard. If it is not, re-adjust. If after re-adjustment the measurement result is still different from the standard, replace the steering gear.

- Rack play: 0.273 mm
22. Before installing the cover, temporarily secure its clamp on the large diameter side.
Caution: Do not reuse clamps, replace them with new ones.
23. Apply special Nissan MP No.2 grease to the covers on the large and small diameter sides.
Warning: Do not reuse covers, replace them with new ones.
24. Install the cover with the small diameter side into the groove of the inner tip, secure the cover with a clamp from the small diameter side.
25. Secure the cover with a clamp on the large diameter side.
(1) Firmly fix the clamp into the groove of the boot and clamp the fastening point with pliers.
(2) Clamp the mounting location so that the gap is less than 3.5mm as shown in the figure.
(3) To avoid contact with other parts, install the steering gear on the vehicle so that the mounting section is in the position shown in the figure.
26. Install the lock nut and the outer end onto the inner end. Tighten the lock nut by hand to adjust the length of the steering rod.
- Steering rod length L: 157.5 mm
Note: After finishing the work, adjust the toe-in. The length L after adjustment is different from the above.
27. Install the steering mechanism assembly on the vehicle, check the rack turning force.
Rack turning force
From the neutral position ±11.5 mm, the amplifier works:
- Average force value: 235.2-294.0 N (23.99-29.97 kg)
- Deflection: 117 N (12 kg) or less
Throughout the entire range of motion of the rack:
- Maximum force value (the amplifier does not work): 294 N (30 kg) or less
- Deflection: 147 N (15 kg) or less
