5) Check relief pressure
Increase engine speed to about 1,500 r / min (rpm). Close
gauge valve gradually while watching pressure increase indi-
cated by gauge and take reading of relief pressure (maximum
hydraulic pressure).
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa
(67 ± 75 kg / cm
2, 953 ± 1067 psi) J20 Type engine. . . . . . .
7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .
When it is higher than specified values, possible cause is mal-
function of relief valve.
When it is lower than specified values, possible cause is either
failure of P / S pump or settling of relief valve spring.
CAUTION:
Be sure not to close gauge valve for longer than 10 se-
conds.
Next, open gauge valve fully and increase engine speed to
about 1,500 r / min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
Relief pressure:
6200 ± 7000 kPa
(62 ± 70 kg / cm
2, 882 ± 995 psi) G16 Type engine. . . . . . .
6700 ± 7500 kPa

7050 ± 7850 kPa
(70.5 ± 78.5 kg / cm
2, 1003 ± 1116 psi) H25 Type engine. .
When it is higher than specified values, possible cause is mal-
function of relief valve.
When it is lower than specified values, possible cause is failure
in steering gear box. Replace gear box.
CAUTION:
Be sure not to hold steering wheel at fully turned posi-
tion for longer than 10 seconds.
BOOT
STEERING RACK BOOT CHECK
Check boot for crack and damage which, if any, means possibility
of rusty gear, entry of dust or lack of grease. Also, check if any of
such faulty conditions exists.
Check steering rack boot for dent or breakage.
If there is a dent, keep boot in most compressed state for some se-
conds to correct dent.

(NOT EQUIPPED WITH AIR BAG)
NOTE:
All steering wheel and column fasteners are important parts in that they could affect the performance of
vital parts and systems, and / or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality of substitute design. Torque values must be used as specified during reassemb-
ly to assure proper retention of this part.

GENERAL DESCRIPTION
This double tube type steering column has the following three important features in addition to the steering function:
The column is energy absorbing, designed to compress in a front-end collision.
The ignition switch and lock are mounted conveniently on this column.
With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehicle.
To insure the energy absorbing action, it is important that only the specified bolts be used as designated and that
they are tightened to the specified torque. When the column assembly is removed from the vehicle, special care
must be taken in handling it. Use of a steering wheel puller other than the one recommended in this manual or a
sharp blow on the end of the steering shaft, leaning on the assembly, or dropping the assembly could shear the
plastic shear pins which maintain column length and position.

4) Check steering column lower seal for breakage or deformation.
If found defective, replace.
5) Check steering shaft joints and shaft for any damages such as
crack, breakage, malfunction or excessive play.
If anything is found faulty, replace as steering lower shaft assem-
bly or steering column assembly.
6) Check steering shaft for smooth rotation.
If found defective, replace as column assembly.
7) Check steering shaft and column for bend, cracks or deforma-
tion.
If found defective, replace as column assembly.
INSTALLATION
CAUTION:
After tightening steering column mounting bolts, steering
shaft joint bolts should be tightened.
After tightening steering column lower bolts, steering col-
umn upper bolts should be tightened.
1) Be sure that front wheels and steering wheel are in straight-
ahead position.
2) If equipped with shift (key) interlock cable, install shift (key) inter-
lock cable to ignition switch.
3) Install steering column assembly to dash panel and upper
bracket so that boss of steering column lower seal and all around
it project out of hole in dash panel into engine room. Tighten
steering column lower bolts (4 pieces) first and then upper bolts
(2 pieces) to specified torque.
