d.

Wrap an OHP sheet [approximately 70 mm (2.76 in) 

×

 100 mm

(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
with OHP sheet until they pass rack edge, and remove OHP
sheet.

e.

Install end cover assembly to rack edge, and move rack oil seal
(outer) until it contacts with gear housing assembly.

5.

Tighten end cover assembly to specified torque using a 36 mm
(1.42 in) open head (suitable tool).

CAUTION:

Never damage rack assembly. Replace it if damaged
because it may cause fluid leakage.

6.

Crimp gear housing assembly at one point using a punch as
shown in the figure so as to prevent end cover assembly from
getting loose after tightening end cover assembly.

7.

Apply recommended fluid to O-ring, and then install O-ring to
gear housing assembly.

8.

Install gear-sub assembly to gear housing assembly.

CAUTION:

In order to protect oil seal from any damage, insert gear-
sub assembly straightly.

9.

Install inner socket and spacer to gear housing assembly with
the following procedure.

a.

Apply recommended thread locking sealant into the thread of inner socket.
Use Genuine High Strength Thread Locking Sealant, Loctite 271 or equivalent.

b.

Screw inner socket into rack part and tighten at the specified torque.

10. Decide on the neutral position of the rack stroke (L).

11. Install rear cover cap to gear sub-assembly.

CAUTION:

Make sure that the projection of rear cover cap is aligned
with the marking position of gear housing assembly.

12. Apply recommended sealant into the thread of adjusting screw

(2 turns thread), and then screw in the adjusting screw until it
reaches height “H” from gear housing assembly measured
before disassembling.
Use Genuine Liquid Gasket, Three Bond 1111B or equiva-
lent.

13. Move rack assembly 10 strokes throughout the full stroke so that

the parts can fit with each other.

14. Adjust pinion rotating torque with the following procedure.
a.

Measure pinion rotating torque within 

±

180

°

 of neutral position

of the rack assembly using Tools. Stop the gear at the point
where highest torque is read.

b.

Loosen adjusting screw and retighten to 5.4 N·m (0.55 kg-m, 48
in-lb), and then loosen by 20 to 40

°

.

c.

Measure pinion rotating torque using Tools to make sure that the
measured value is within the standard. Readjust if the value is
outside the standard. Replace steering gear assembly, if the
value is outside the standard after readjusting, or adjusting
screw rotating torque is 5 N·m (0.51 kg-m, 44 in-lb) or less.

d.

Apply recommended liquid gasket to inner socket and turn pinion fully to left with inner socket installed to
gear housing assembly.

e.

Install dial indicator at 5 mm (0.20 in) (L) from the edge of gear
housing assembly (1), and tooth point.

f.

Measure vertical movement of rack assembly when pinion is
turned clockwise with torque of 19.6 N·m (2.0 kg-m, 14 ft-lb).
Readjust adjusting screw angle if the measured value is outside
the standard.

• If reading is outside of the specification, readjust screw angle

with adjusting screw.

CAUTION:

• If reading is still outside 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.

• Never turn adjusting screw more than twice.
• Replace steering gear assembly when adjusting screw is removed or turned more than twice.

15. Install large end of boot to gear housing assembly.

16. Install small end of boot to inner socket boot mounting groove.
17. Install boot clamp to boot small end.

18. Install boot clamp to the large side of boot with the following procedure.

CAUTION:

Never reuse boot clamp.

a.

Tighten large side of boot with boot clamp (stainless wire).

b.

Wrap clamp around boot groove for two turns. Insert a flat-
bladed screwdriver in loops on both ends of wire. Twist 4 to 4.5
turns while pulling them with force of approximately 98 N (10 kg,
22 lb).

c.

Twist boot clamp as shown. Pay attention to relationship
between winding and twisting directions.

d.

Twisted area (A) of clamp is in the opposite side of adjusting
screw (1) as shown in the figure (to prevent contact with other
parts).

e.

Bent cut end of the wire toward rack axial as shown in the figure
after twisting the wire 4 to 4.5 turns so that cut end does not con-
tact with boot.

19. Install cylinder tubes to gear housing assembly.
20. Install low pressure piping.

21. Adjust inner socket to standard length (L), and then tighten lock

nut to the specified torque. Check length again after tightening
lock nut.

Adjust toe-in after this procedure. The length achieved after
toe-in adjustment is not necessary the above value.

Inspection

INSPECTION AFTER INSTALLATION

• Check if steering wheel turns smoothly when it is turned several times fully to the end of the left and right.
• Check the steering wheel play, neutral position steering wheel, steering wheel turning force, and front wheel

turning angle. Refer to 

ST-9, "Inspection"

.

• Check the fluid level, fluid leakage, and air bleeding hydraulic system. Refer to 

ST-7, "Inspection"

.

INSPECTION AFTER DISASSEMBLY

Boot

Check boot for cracks, and replace it if a malfunction is detected.
