pinion.

CAUTION:
Be sure to use a new gasket.

NOTE:
Do not allow packing to be caught when installing
valve assembly.

15) Tighten bolts alternately to secure valve as-
sembly.

 Tightening torque:

25 N·m (2.5 kgf-m, 18.1 ft-lb)

CAUTION:
Be sure to alternately tighten bolts.
16) Apply grease to sleeve insertion hole.
17) Apply grease to dust seal insertion hole.

CAUTION:
Apply clean grease with clean hands. If material 
having a sharp edge is used for applying 
grease, oil seal at the inside might be damaged.
18) Apply grease to sliding surface of sleeve and
spring seat, then insert sleeve into pinion housing.
Fit spring into sleeve screw, pack grease inside of
screw, then install the screw.

19) Rack and pinion backlash adjustment

(1) Loosen adjusting screw.

(2) Rotate input shaft so that rack is in the
straight ahead direction.
(3) Apply grease to sleeve.

(4) Tighten adjusting screw by approx. two
threads.

(5) Apply liquid packing to at least 1/3 of entire
perimeter of adjusting screw thread.

Liquid packing:

THREE BOND 1141

(6) Tighten adjusting screw to 7.4 N·m (0.75
kgf-m, 5.4 ft-lb) and back off 25

Tightening torque (Lock nut):

39 N·m (4.0 kgf-m, 29 ft-lb)

NOTE:
• Hold adjusting screw with a wrench to prevent it
from turning while tightening lock nut.
• Make adjustment so that steering wheel can be
rotated fully from lock to lock without binding.
20) Check for service limit as per article of “Service
limit”. <Ref. to PS-47, SERVICE LIMIT, INSPEC-

E: INSPECTION

1. BASIC INSPECTION

1) Clean all disassembled parts, and check for wear, damage, or any other faults, then repair or replace as
necessary.
2) When disassembling, check inside of gearbox for water. If any water is found, carefully check boot for
damage, input shaft dust seal, adjusting screw and boot clips for poor sealing. If faulty, replace with new
parts.

No.

Parts

Inspection

Corrective action

1

Input shaft

(1) Bend of input shaft
(2) Damage on serration

If bend or damage is excessive, replace entire gearbox.

2

Dust seal

(1) Crack or damage
(2) Wear

If outer wall slips, lip is worn out or damage is found, 
replace it with new one.

3

Rack and pinion

Poor mating of rack with pinion

(1) Adjust backlash properly. 
By measuring turning torque of gearbox and sliding resis-
tance of rack, check if rack and pinion engage uniformly 
and smoothly with each other. (Refer to “Service limit”.)
(2) Keeping rack pulled out all the way so that all teeth 
emerge, check teeth for damage. 
Even if abnormality is found in either (1) or (2), replace 
entire gearbox.
