CAUTION:

Secure steering gear assembly with a vise, using copper
plates or something similar to prevent it from being dam-
aged. Do not grip cylinder with a vise.

Before performing disassembly, clean steering gear assem-
bly with kerosene. Be careful not to bring any kerosene into
contact with the discharge and return port connectors.
DISASSEMBLY
1. Remove cylinder tubes from gear housing assembly.
2. Remove rear cover cap from gear housing assembly.
3. Measure adjusting screw height from gear housing assembly, then loosen adjusting screw.
CAUTION:

Do not turn adjusting screw more than twice.

Replace steering gear assembly when adjusting screw is
removed or more than twice.
4. Use a rear cover wrench (SST) to remove rear cover from sub- gear assembly.
5. Remove O-ring with a flat-bladed screwdriver, and pull out rear cover.
6. Remove sub-gear assembly from gear housing assembly. CAUTION:
In order to protect oil seal from any damage, pull sub-gear
assembly out straightly.
7. Loosen lock nut of outer socket, and remove outer socket.
8. Remove boot clamps of the small diameter side and the large diameter side, then remove boot.

9. Use a rear cover wrench (SST), install rear cover to gear housing assembly.
10. Confirm projection on rear cover cap nearly fit with marking position on gear housing assembly.
11 . A p p l y t h r e a d l o c k i n g a d h e s i v e ( T h r e e B o u n d T B 1111 B o r e q u i v - alent. Refer to GI-48
) to the thread of adjusting screw to the
adjusting screw height from gear housing assembly. The adjust-
ing screw height is the same as it was measured in the overhaul
in advance.
12. Rotate pinion ten times whole range of rack so that parts get to fit with each other.
13. Measure pinion rotating torque within from –180 ° to +180 °,
make preload gauge (SST) and torque adapter (SST) in rack
neutral position, then hold preload gauge (SST) at maximum
torque.
14. After loosening adjusting screw once, tighten it again with torque of 5.4 N·m (0.55 kg-m, 48 in-lb). After that loosen it within 20 ° to
40 °.
15. Measure pinion rotating torque with torque adapter (SST) and preload gauge (SST), then confirm whether it's reading is within
the specified value. If the reading is not within the specified
value, readjust screw angle with adjusting screw. Change gear
assembly to new one, if the reading is still not within the speci-
fied value or the rotating torque of adjusting screw is less than 5
N·m (0.51 kg-m, 44 in-lb).
16. Turn pinion fully to the end of the left with inner socket to gear housing assembly.
17. Set dial gauge to rack as shown in the figure. Measure vertical movement of rack when pinion is turned counterclockwise with
torque of 19.6 N·m (2.0 kg-m, 14 ft-lb). Check reading is within
the specified value. If reading is outside of the specification,
readjust screw angle with adjusting screw. If reading is still out-
side of specification, or if the rotating torque of adjusting screw is
less than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear
assembly.

Pinion rotating torque:
Around neutral position (within ±100 °)
Average “A”:
0.8 − 2.0 N·m (0.08 − 0.20 kg-m, 7 − 18 in-lb)
Other than above (more than ±100 °)
Maximum variation “B”:

18. Install large-diameter side of boot to gear housing assembly.
19. Install small-diameter side of boot to the mounting groove of inner socket boot.
20. Install boot clamp to the small-diameter side of boot.
21. Install boot clamp to the large-diameter side of boot.
NOTE:
Do not reuse boot clamp.
a. Tighten large-diameter side of RH/LH boot with boot clamp (stainless wire).
b. After wrapping clamp around boot groove for two turns, insert screwdriver in loop on both ends of wire. Twist 4 to 4.5 turns
while pulling with a force of approx. 98 N (10 kg, 22 lb).
c. Twist boot clamp as shown in the figure, pay attention to rela- tionship between winding and twisting directions.
22. Install cylinder tubes to gear housing assembly.
23. Install lock nut and outer socket to inner socket. Amount of vertical movement with rack Less than 0.265 mm (0.01 in)
Measuring point Axial direction of rack 5 mm (0.2 in) away from
end of gear housing
Radius direction of rack Shaft direction of adjust- ing screw
