Description
Hydraulic Flow (cont'dl
3rd Gear
The flow of fluid up to the 1-2 and 2-3 shift valve is the same as in 2nd gear. As the speed of the vehicle reaches theprescribed value. the shift control solenoid valve B is turned OFF (shift control solenoid valve A remains ON). The 2-3
shift valve is then moved to the left, uncovering the port leading to the 3rd clutch. Since the 3-4 shift valve is moved
to the right to vover the port to the 4th clutch, the 3rd clutch is turned on.
Fluid flows by way of:- Line pressure (4) rj) 1-2 Shift Valve + 2-3 Shift Valve - 3rd Clutch Pressure (31) r 3-4 Shift Valve(not controlledl - 3rd Clutch Pressure (30) + 3rd Clutch
The hydraulic pressure also flows to the lst clutch. However, no power is transmitted because of the one-way clutch
as in the 2nd gear.
NOTE: When used, "|eft" or "right" indicates direction on the hydraulic circuit.

The flow of fluid up to the 1-2, 2-3 and 3-4 shift valves is the same as in 3rd gear. As the speed of the vehicle reaches
the prescribed value, the shift control solenoid valve A is turned OFF (shift control solenoid valve B remains OFF). As
this takes place, 3-4 shitt valve is moved to the left and uncovers the port leading to the 4th clutch. Since thel-2 and 2-
3 shift valves are kept on the left side, the fluid flows through the 4th clutch; the power is transmitted through the 4th
clutch.
Fluid flows by way of:- Line pressure (4) + 1-2 Shift Valve ) 2-3 Shift Valve - 3rd Clutch Pressure (3'1) -t 3-4 Shift Valve -
4th Clutch pressure (41) + Manual Valve - 4th Clutch Pressure (40) + 4th Clutch
The hvdraulic pressure also flows to the 1st clutch, However, no power is transmitted because of the one-way clutch
as in 2nd and 3rd gears.

8. Recheck the tapered roller bearing preload.
9. How to select the correct 79.5 mm shim:
1) Compare the tapered roller bearing preload you
get with the 79.5 mm shim that was removed
with the soecified mean Dreload of 2.50 N'm
(25.5 kgf .cm, 22 lbf.in).- 2l ll vour measured tapered roller bearing preload
is less than specified, subtract your's from the
specitied.
lf vour's is more than specitied, subtract the
soecified from vour measurement.
For example with a 1.38 mm {0.0543 in) shim:
@ specified 2.50 N.m (25.5 kgf.cm, 22 lbl.in)- you measure 0.54 N.m (5.5 kg{.cm, 5lbl.in}
2.0 N.m (20 kgf.cm, 18lbf.in) less
@you measure 3.29 N.m (33.5 kgI.cm, 29 lbt.in)- specified 2.50 N.m (25.5 kgf.cm, 22 lbf.in)
0.8 N.m (8 kgf.cm,7lbf.in) more
-3) Each shim size up or down from standard
makes about O.3-0.4 N.nt (3-4 kgf.cm,
2.6-3.5 lbl.in) difterence in tapered roller
bearing preload.
a In example @, your measured tapered roller
bearing preload was 2.O N.m (2O kgt.cm,
18 lbf in) less than standard so you need a
79.5 mm shim live sizes thicker than stan-
dard {try the 1.53 mm (O.0602 in) shim and
recheck).
a ln example @ your's was 0.8 N.m {8
kgf.cm,7lbf.in) more than standard. so
you need a thrust shim two sizes thinner (try
the 1 .32 mm (O.O52O in) shim and recheck).
1O. After adjusting the tapered roller bearing preload, as-
semble the transmission, and installthe lransmission
housing (see section 13).

to seat the tapered roller bearings.

to the next size will increase or decrease tapered
roller bearing preload about 0.3 - 0.4 N'm (3 - 4

8. How to select the correct 79,5 mm shim:-1) Compare the tapered roller bearing preload you
get with the 79.5 mm shim that was removed
with the sDecified preload of 2.50 N'm (25.5
kgf.cm, 22 lbf.in).-2) lf vour measured tapered roller bearing preload
is less than specified, subtract your's from the
sDecified.
lf your's is more than specified, subtract the
specified from your measurement.
For example with a 1.38 mm (0.0543 in) shim:
@ specified 2.50 N.m (25.5 kgf.cm,22 lbiin)- you measure 0.54 N.m (5.5 kgf'cm, 5 lbf in)
2.0 N.m (20 kgf.cm, 18 lbf.in) less
@ you measure 3.29 N.m (33.5 kgf.cm, 29 lbf in)
- specified 2.50 N'm (25.5 kgf'cm, 22 lbf in)
0.8 N.m {8 kgf.cm. 7 lbf in) more
-3) Each shim size up or down from standard
makes about 0.3 - 0,4 N.m (3 - 4 kgf'cm,
2.6 - 3.5 lbf.in) difference in tapered roller
bearing preload.
o In example @, your measured tapered roller
bearing preload was 2.0 N.m (20 kgf.cm,
18 lbf.in) less than standard so you need a
79.5 mm shim five sizes thicker than stan-
dard (try the 1.53 mm (0.0602 in) shim and
recheck).
. In example @, your's was 0.8 N.m (8
kgf.cm,7 lbf.in) more than standard, so you
need a thrust shim two sizes thinner (try
the 1.32 mm {0.0520 in) shim and recheck).
Recheck the tapered roller bearing preload.
After adjusting the tapered roller bearing preload,
assemble the transmission, and install the transmis-
sion housing.
Rotate the difterential assembly in both directions
to seat the tapered roller bearings.

System DescriPtion
Steering Gearbox
it
The rack,and-pinion type steering gearbox has a Valve body unit incorporated with the pinion to control the steering fluid
pressure. steering fluid from the pump is regulated by a rotary valve in the valve body unit and is sent through the cylin-
derpipetothepowercy|inder,wherehydrauIicpressureisapp|ied.Thesteeringf|Uidintheothersideofthepowercy|in-
der returns through the cylinder pipe and valve body unit to the reservoir'
Valve Body Unit
Inside the valve body unit is the valve, which is coaxial with the pinion shaft, and controls the steering fluid pressure The
valve housing ls connected wirh the fluid pipe from the pump. return pipe to the reservoir, and the two cylinder pipes
from the respective power cylinder.
The pinion shaft is double - structured with the input shaft connected to the pinion gear, both of which are interconnected
with the torsion bar.
The pin inserted in the valve and the pinion shaft groove engage; this allows the pinion shaft to rotate together with the
Because of this construction. the difference in angle in the circumferential direction between the input shaft and the valve
becomes larger according ro the torsional strength ol the pinion or steering resistance. However. maximum torsion
between the shafts is regulated by the engaged splines of the shafts at the pin engagement section to hold the torsion bar
within the set value.
This allows the steering system to function as an ordinary rack-and-pinion type steering if the steering iluid is not pressur-
ized because of a faulty PumP.
