S@ to pttvont iniury to face and syes' always
w6ar safety glassos or a face shield when using the trans-
mission flusher.
NOTE: This procedure should be performed before rein-
stalling the transmission.
1. Check tool and hoses for wear and cracks before
using. lf wear or cracks are found, replace the hoses
before using.
2. Using the measuring cup, fill the tank with 21 ounces
(approximately 2/3 full) of biodegradable tlushing
fluid {J35944-20). Do not substitute with any orher
tluid. Follow the handling procedure on the tluid
contalner.
3. Secure the flusher filler cap, and pressurize the tank
with compressed air to between 550-829 kPa
{5.6-8.45 kgf /cm', 80- 120 Psi}.
NOTE: The air line should be equipped with a water
trap to ensure a dry air system.
4. Hang the tool under the vehicle
5. Attach the discharge hose of the tank to the return
line oI the transmission cooler using a clamp
6. Connect the drain hose to the inlet line of the trans-
mission coolel using a clamp. Securely clamp the op-
oosite end of the drain hose to a bucket or tloor drain.

7. With the water and air valves ofl, atach the water
and air supplies to the flusher. (Hot water if
available.)
8. Turn on the flusher water valve so water will flow
through the ATF cooler for 10 seconds. lf water does
not flow through the ATF cooler, it is completely
plugged, cannot be flushed, and must be replaced
9. Depress the trigger to mix the flushing fluid into the
water flow. Use the wire clip to hold the trigger
oown.
1O. While tlushing with the water and llushing f luid for

1 1. Turn the water valve off. Release the trigger. then
reverse the hoses to the cooler so you can flush in
the ooDosite direction. Repeat steps 8 through 1O.
12, Release the trigger and allow water only to rinse the
cooler with water for one minute.
13. Turn the water valve oJf and turn off the water
supply.
'14. Turn the air valve on to dry the system out with air
for two full minutes or until no moisture is visible
leaving the drain hose.
CAUTION: Residual moisture in the ATF coolei 01
pipos can damage the transmission.
15. Remove the flusher {rom the cooler line. Attach the
drain hose to a fluid contaaner.
16. Installthe transmission and leave the drain hose a1-
tached to the cooler line.

System Description
Fluid Flow Diagram
The system is a compact rotary-valve-type power steering, connected to the steering gearbox. The fluid pressure is pro-
vided by a vane-type pump which is driven by the engine crank pulley. The amount of fluid and pressure is regulated by
the flow control valve built into the pump. The fluid pressure from the pump is delivered to the valve body unit around the
pinion of the steering gearbox. The valve inside the valve body unit controls the hydraulic pressure and changes the direc-
tion of the tlow. The fluid then flows to the power cylinder, where rack thrust is generated. Fluid returning from the power
cylinder flows back to the reservoir, where the fluid is "filtered" and supplied to the pump again

Steering Pump
Construc'tion
The pump is a vane-type incorporating a flow control valve (with an integrated relief valve) and is driven by a POLY-V-belt
from the crank pulley. The pump features 10 vanes. Each vane performs two intake/discharge operations for every rota-tion of the rotor. This means that the hydraulic fluid pressure pulse becomes extremely small during discharge.
Operation
The belt-driven pulley rotates the rotor through the drive shaft. As the rotor rotates. the hydraulic pressure is applied tothe vane chamber of the rotor and the vanes will rotate while being pushed onto the inner circumference of the cam ring.The inner circumference of the cam ring has an extended portion with respect to the center of the shaft, so the rollersmove downward in the axial direction as the carrier rotates. As a result of this roller movement, the internal volume of thevane chamber will change. resulting in fluid intake and discharge.

The vanes are pushed onlothe inner circumference of thecam ring.
The volume of the vane cham-ber increases so that fluid issucked in.
The sucked in fluid movestoward the discharge port.As the vanes return to thetheir original position on theinner side, the volume of thevane chamber decreases sothe fluid is discharged fromthe discharge port-
