>>D<< OIL SEAL/RACK BUSHING
INSTALLATION
1. Apply ATF DEXRON III or DEXRON II to the outer
surface of the oil seal. Using special tool installer
adapter (MB990927), press in the oil seal until it is
flush with the bushing end face.
2. Apply ATF DEXRON III or DEXRON II to the oil
seal inner surface and the O-ring.
3. Wrap the rack end with plastic tape, and push the
rack bushing onto the rack.
>>E<< CIRCLIP INSTALLATION
CAUTION
Insert the circlip to the rack stopper hole while
turning the rack stopper clockwise.
Insert the circlip to the rack stopper hole through
cylinder hole. Turn the rack stopper clockwise and
insert the circlip firmly.
>>F<< UPPER OIL SEAL/UPPER
BEARING INSTALLATION
Apply a coating of ATF DEXRON III or DEXRON II to
the outside of the upper oil seal/upper bearing. Using
the following special tools, press the upper oil
seal/upper bearing into the valve housing.
•MB990938: Bar (Snap-in type)
•MB991203: Oil Seal and Bearing Installer
>>G<< SEAL RINGS INSTALLATION
Because the seal rings expand after installation,
tighten after installing by using special tool seal ring
installer (MB991317) to compress the rings, or press
down by hand.

>>H<< LOWER OIL SEAL INSTALLATION
CAUTION
To eliminate a seal malfunction at the valve
housing alignment surface, the upper surface of
the oil seal should project outward
approximately 1 mm from the housing edge
surface.
Using special tool torque tube bearing installer
(MB990941), press the oil seal into the valve
housing.
>>I<< END PLUG INSTALLATION
1. Apply specified sealant to the threaded part of the
end plug.
Specified sealant: 3M ATD Part No.8661,
8663 or equivalent
2. Secure the threaded portion of the end plug at two
places by using a punch.
>>J<< RACK SUPPORT COVER/LOCK
NUT INSTALLATION
1. Position the rack at its centre.
2. Apply specified sealant to the threaded part of the
rack support cover.
Specified sealant:
3M ATD Part No.8661, 8663 or equivalent3. Use the following special tool to tighten the rack
support cover to 23 ± 2 N⋅m.
•MB990607: Torque Wrench Socket
•MB991621: Piston Driver
4. Turn the rack support cover 30° anticlockwise.
5. Use the special tool to hold the rack support
cover, and then tighten the lock nut to 59 ± 10
N⋅m.
>>K<< TOTAL PINION TORQUE
ADJUSTMENT
CAUTION
•Be sure there is no ratcheting or catching
when operating the rack towards the shaft.
•Measure the total pinion torque through the
whole stroke of the rack.
1. Using special tool preload socket (MB991006),
rotate the pinion shaft at the rate of one rotation in
4 to 6 seconds to check the total pinion torque and
the change in torque.
Standard value:
Total pinion torque: 0.8 − 2.1 N⋅m <1300,
1600(Comfort)>
[Change in torque: 0.6 N⋅m or less]
Total pinion torque: 0.7 − 2.1 N⋅m <1600(Sport),
2000>
[Change in torque: 0.6 N⋅m or less]

CAUTION
When adjusting, set at the highest value of the
standard value range.
NOTE: If the total pinion toque cannot be adjusted
to the standard value within the specified return
angle, check the rack support cover components
and replace any parts if necessary.
2. If the total pinion torque or the change in torque is
outside the standard value, move the rack support
cover 0 − 30°, and adjust the pinion torque again.
>>L<< TAB WASHER/TIE ROD
INSTALLATION
After installing the tie rod to the rack, fold tab washer
end (two locations) to tie rod notch.
>>M<< BELLOWS BAND INSTALLATION
1. Turn the adjusting bolt of special tool boot band
crimping tool (MB991561) to adjust the opening
dimension (W) to the standard value.
NOTE: The dimension (W) is adjusted by
approximately 0.7 mm per one turn.
NOTE: Do not turn the adjusting bolt more than
one turn.
Standard value (W): 2.9 mm: Screw in the
adjusting bolt.
: Loosen the
adjusting bolt.
CAUTION
•Hold the rack housing, and use special tool to
crimp the bellows band securely.
•Crimp the bellows band until special tool
touches the stopper.
2. Use special tool boot band crimping tool
(MB991561) to crimp the bellows band.
3. Check that crimped width (A) is within the
standard value.
Standard value (A): 2.4 − 2.8 mm
: Readjust the
dimension (W) of step (1) to the value
calculated by the following equation, and
repeat step (2).
W = 5.5 mm − A [Example: if (A) is 2.9 mm,
(W) is 2.6 mm.]
: Remove the
bellows band, readjust the dimension (W) of
step (1) to the value calculated by the
following equation, and use a new bellows
band to repeat steps (2) to (3).
W = 5.5 mm − A [Example: if (A) is 2.3 mm,
(W) is 3.2 mm.]
