Power Steering Gearbox
Reassembly (cont'd)
d. Determine the required thickness of the 44 mm
shims by subtracting the clearance obtained in the
step - "C" from the total thickness of the four shims.
(Total thickness of the four shims) - (Clearance) =
Required thickness of the shims
NOTE: 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):
0.07 - 0.28 = 0.42 mm (0.028 - 0.011 = 0.017 in)
The selected shims should be 0.25 mm (0.010 in) and
0.15 mm (0.006 in) in thickness.
If the required shim thickness is 0.10 mm or less, no
shims are necessary.
55. Set the selected 44 mm shims on the bearing surface
of the gearbox housing.
56. Coat the new O-ring with grease, and carefully fit it
on the valve housing.
57. Apply grease to the needle bearing in the gearbox
housing.
58. Install the valve body unit on the gearbox housing
by engaging the gears.
NOTE: Note the valve body unit installation position
(direction of line connection).
59. Tighten the flange bolts to the specified torque.
60. Install cylinder lines A and B.
NOTE:
• Clean the joints of cylinder lines A and B
thoroughly. The joints must be free of foreign
material.
• Install cylinder lines A and B by lighting the flare
nuts by hand first, then tighten the flare nuts to
the specified torque.
61. Grease the sliding surface of the rack guide, and
install it onto the gearbox housing.
62. For '96 - 98 models: Apply a thin coat of grease to
the new 0-ring, and install it on the rack guide screw.
For '99 - 01 models: Apply sealant to the all around
threads on the rack guide screw.
63. Install the spring, rack guide screw and locknut on
the gearbox housing.
64. Adjust the rack guide screw (see page 17-16).
NOTE: After adjusting, check that the rack moves
smoothly by sliding the rack right and left.
