Note these items when pressing the cylinder end
seat:
. Keep the tool straight to avoid damaging the
cylinder wall. Check the tool angle, and correct it if
necessary, when removing the cylinder end seal.
. Use a press to remove the cylinder end seal. Do
not try to remove the seal by striking the tool. lt
will break the backup ring, and the cylinder end
sealwill remain in the gearbox.

VALVE HOUSING
Separate the valve housing from the pinion shafv
valve using a press.
Check the inner wall of the valve housing where the
seal ring slides with your finger. lf there is a step in
the wall, the valve housing is worn. Replace the
valve housing.
Note these items during inspection:
o There may be the sliding marks from the seal
ring on the wall of the valve housing. Replace
the valve housing only if the wall is stepped.
. When the valve housing is replaced, install new
shim{s) on the bearing surface of the housing to
adiust the thickness.
Check the inside ofvalve housingfor a step in the wall.

Apply power steering fluid to the surface of the spe-
cial tool. Set the new seal rings over the special tool
from the smaller diameter end of the tool. and
expand the seal rings. Install two rings at a time
Jrom each end ofthe sleeve.
Note these items when installing the seal ring:
. Do not over-expand the seal ring. Install the resin
seal rings with care so as not to damage them.
After installation, be sure to contract the seal
rings using the specialtool {sizing tool).
. There are two types of sleeve seal rings: black
and brown. Do not mix the different types of
sleeve seal rings as they are not compatible.
Align the special tool with each groove in the sleeve,
and slide a sleeve seal ring into each groove. After
installation, compress the seal rings with your fin-
gers temporarily.

NOTE: Only reinstall the original 32 mm shim(s)
when the steering gearbox is reassembled without
replacing the pinion shaft. valve housing, and gear-
box housing with new ones.
lf the pinion shaft, valve housing, and gearbox
housing are replaced, select the new shim{s) as fol-
lows.
Shim selection:
Set the four 32 mm shims on the bearing surface of the
gearbox housing. Total thickness of the four shims
should equal no more than 0.70 mm.
Shim set: four 32 mm shims (Thickness: 0.10 mm, 0.15
mm, 0.20 mm, 0.25 mm respectively)
NOTE: The four 32 mm shims do not have thickness
identification marks. Measure the thickness of each shim
using a micrometer, and mark the shim for identification.

SHIM SET(four shims)
Measure the clearance between the gearbox and
valve body unit using a feeler gauge. Measure the
clearance at the poinl midway between the two
mounting bolts.
GAUGE
Determine the required thickness of the 32 mm
shims by subtracting the clearance obtained in the
step "c" from the total thickness of the four shims.
(Total thickness of the 4 shims) - (Clearance) =
Reouired thickness of the shims
Select the shims so that the total thickness is close
to, but less than, the required thickness.
Example:
Measurement is 0.28 mm (0.011 in);
0.70-0.28=0.42 mm (0.028-0.011 = 0.017 in)
The selected shims should be 0,25 mm (0.010 inl and
0.15 mm (0.006 in) in thickness.
lf the required shim thickness is 0.10 mm or less, no
shrms are necessary.
53. Set the selected 32 mm shims on the bearing sur-
face of the gearbox housing.
VALVE BODY UNITla lbl.frl
Coat the new O-ring with grease, and carefully fit it
on the valve housing.
Apply grease to the needle bearing in the gearbox
housing.
Install the valve body unit on the gearbox housing
by engaging the gears. Note the valve body unit
installation position (direction of line connection).
Tighten the flange bolts to the specified torque.
