Install I new set ring on the end of each driveshaft.
Install the right and left driveshafts (see section 16).
CAUTION: While instatling the drive3hafts in thedifferential, be sure not to allow dust and olher for-aign particles to enter into tho transmission.
NOTE:
. Clean the areas where the driveshafts contact thetransmission {differential} thoroughly with sol-vent or carburetor cleaner, and drv with com-
Dressed air.
. Turn the right and left steering knuckle fully out-wa.d, and slide each driveshaft into the differen-tial until you feel its set ring clip engage the sidegear.
Install the damper fork, then install the right and leftball joints to each lower arm with the castle outsand new cotter pins.

8. Remove the cotter pin from the lawer arm ball joint

Install a 12 mm hex nut on the ball joint. Be sure
that the hex nut is flush with the ball joint pin end,
or the threaded section of the ball joint pin might be
damaged by the special tool.
Use the special tool as shown in section 18, to sepa-
rate the ball joint and lower arm. Be careful not to
damage the ball joint boot.
NOTE: lf necessary, apply penetrating type lubri,
cant to loosen the ball joint.
Pry the driveshaft assembly with a screwdriver, as
shown, to force the set ring at the driveshaft endpast the groove.

System Description
Steering Pump (cont'dl
The flow control valve and sub-valve in the pump per-
forms the following steps @ through @ to control the
flow of fluid, that is to increase the discharge volume
when engine speed is low, and to decrease it when the
engine speed increases. The assistance thrust of the
steering gearbox changes in compliance with the
change in the discharge volume.
When the engine starts, fluid discharged from the
discharge port starts to flow through oil passage A,
the fixed orifice and the variable orifice to the steer-
ing gearbox. When the engine speed is extremely
low, the return port is closed by the flow control
Fluid pressure discharged from the discharge port
is applied to the top of the sub-valve, and the fluid
pressure that passed through oil passage A is applied
to the bottom of the sub-valve. When this happens,
the pressure difference between the ends of oil pas-
sage A, which is caused by the resistance oil passage
A when the fluid flows through the passage. is
applied to the sub-valve, However, the pressure dif-
ference applied to the sub-valve. that is the force
that pushes the sub-valve down, is too small to
overcome the spring force, and the variable orifice is
fully open when the engine speed is extremely low.
Because the fluid volume flowing through the fixed
orifice and variable orifice increases, a pressure dif-
terence is created between the ends of these ori-
fices, and it increases in proportion to the engine
speed. As the fluid pressure that passed the fixed
orifice and variable orifice is directed to the bottom
of the flow control valve. a pressure difference is
created between the top and bottom of the valve,
which pushes down the flow control valve and
opens the return port. As a result, pan of the fluid
discharged from the discharge port feturns to the
pump suction port, keeping the discharge volume
constant.
In this condition, the sub-valve does not move. and
the variable orifice stays fully open.
