ASSEMBLY INSTALLATION
CAUTION
•When reusing the steering column, do not
release the tilt lever until the steering column
shaft has been installed.•When the steering column is replaced, do not
release the tilt lever until it has been installed.
Do not remove the tilt lever fixing band until
the installation has completed.
•When installing the steering column, do not
leave it fixed temporarily at only one point
and make sure the column shaft is not shaken
strongly. If you fail to do, the collision
absorbing mechanism at the column shaft
mounting location may be damaged.
Ensure that the tilt lever is in the lock position, and
install the steering column. Tighten the four bolts in
the order shown by hand, and then tighten them to
the specified torque in the order shown.

<> CIRCLIP REMOVAL
CAUTION
If the rack stopper is first turned anticlockwise,
the circlip will get caught in the slot in the
housing and the rack stopper will not turn.
1. Turn the rack stopper clockwise until the end of
the circlip comes out of the slot in the rack
housing.
2. Turn the rack stopper anticlockwise to remove the
circlip.

ASSEMBLY REMOVAL
1. Pull out the rack slowly. Take out the rack stopper
and the rack bushing at the same time.
CAUTION
Do not damage the oil seal press fitting surface.2. Partially bend the oil seal and remove it from the
rack bushing.
<> LOWER BEARING REMOVAL
Use a brass bar or special tool brass bar
(MB990939) to remove the lower bearing from the
valve housing.
<> NEEDLE BEARING REMOVAL
CAUTION
Do not open special tool excessively to prevent

>>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.

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),
