Cooler Flushing
!!!@ To prevent iniury to. face and eyas, always
-ea. safetv glasses ot a face shield when using the
transmission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check the tool and hoses for wear and cracks before
using. lf wear or cracks are found, replace the hoses
before using.
Using the measuring cup, fill the tank with 2'l ounces
(approximately 2/3 full) of biodegradable flushing
fluid (J35944 - 20). Do not substitute with any other
fluid. Follow the handling procedure on the fluid
contarner.
Secure the flusher filler cap, and pressurize the tank
with compressed air to between 550 - 829 kpa (5 6 -
8.45 kgflcm' . 80 - 120Psi).
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
Hang the tool under the vehicle.
Attach the tank's discharge hose to the return line
of the transmission cooler using a clamp.
Connect the drain hose to the inlet line on the trans-
mission cooler using a clamP
IMPORTANT:
Securely clamp the opposite end oJ the drain hose to a
bucket or floor drain.

for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual mobturo in tho cooler or pipas

System Description
Steering Gearbox
The rack-and-pinion type steering gearbox has a valve body unit incorporated with the pinion to control the steering fluidpressure. Steering fluid from the pump is regulated by a rotary valve in the valve body unit and is sent through the cylin,der line to the power cylinder, where hydraulic pressure is applied. The steering fluid in the other side of the power cylin,der returns through the cylinder line and valve body unit to the reservoii.
VALVE EODY UNIT
CYLINDER LINE
To RESERVOm +-From PUMP -;
POWER CYLINDER
Valve Body Unit
Inside the valve body unit is the valve, which is coaxial with the pinion shaft, and controls the steering fluid pressure. Thevalve housing is connected with the fluid line from the pump, the return line to the reservoir, and the two cylinder linesfrom the respective power cylinder. The pinion shaft is double - structured with the input shaft connected to the piniongear, 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 thevalve. Because of this construction, the difference in angle in the circumferential direction between the input shaft and thevalve becomes larger according to the torsional strength of the pinion or steering resistance. However, maximum torsionbetween the shafts is regulated by the engaged splines of the shafts at the pin engagement section to hold the torsion barwithin the set value,
This allows the steering system to function as an ordinary rack-and-pinion type steering if the steering fluid is not pressur-
ized because of a faulty pump,
