S!@ ro prevent iniury to tace and eyes, always
wear safety glas$es or a tace 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 or cracks before
using.
lf wear or cracks are found, replace the hoses be-
fore using.
2. Using the measuring cup, tillthe tank with 21 ounces
{approximately 213 lulll of biodegradable tlushing
fluid (J35944-20). Do not substitute with any other
fluid.
Follow rhe handling procedure on the fluid container.
Secure the tlusher filler cap and pressurize the tank
with compressed air to between 550-829 kPa(5.6-8.45 kgt/cm,, 80- 120 psi),
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 discharge hose of the tank to the return
line of the transmission cooler using a clamp.
Connect the drain hose to the inlet line of the trans-
mission cooler using a clamp. Securely clamp the op-posite end of the drain hose to a bucket or floor drain.

8. Turn on the flusher water valve so water will tlow
through the oil cooler for 1O seconds. lf water does
not flow through the oil cooler it is completely
plugged, cannot be flushed, and must be replaced.
9. Depress the trigger to mix the tlushing lluid into the
water tlow. Use the wire clip to hold the trigger
oown.
10. While flushing with the water and flushing fluid for
2 minutes. turn the air valve on for 5 seconds every
15-20 seconds to create a surging action.
AIR PRESSURE:
MAX 829 kPa (8.45 kgt/cm,, 12O psi)
1 1. Turn the water valve off. Release the trigger, then
reverse the hoses to the cooler so you can flush in
the opposite 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 off 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 oil cooler 01
pipes can damage the transmission.
15. Remove the flusher trom the cooler line. Attach the
drain hose 10 a oil container.
16. lnstallthe transmission and leave the drain hose at-
tached to the cooler line.

System Description
Fluid Flow Diagram
The system is a compact rotary-valvs-type power stssring, connocted to the st€oring gearbox. Th6 fluid pressure is pro-vided by a vane-type pump which is driven by the engine crank pulley. The amount of fluid and pressurs is regulsted bythe flow control valve built into ths pump, The fluid prssaurs from th6 pump is dolivsred to tho valve unit sround the pin-ion of the steering g€arbox. The vslv€ inside the valvs unit controls the hydraulic prossur€ End changos the direction otthe flow. The fluid then flows to the power cylinder, where rack thrust is gen6rat6d. Fluid returning from th6 powsr cylin-der flows back to the .eservoir, where the fluid is 'filtered" and supplied to the pump Egain.
17-4

Construetion
The pump is a vane-type incorporating a flow control valve (with an integrated relief valve) and is driven by a V-belt from
the crank pulley. The pump features 10 vanes, Each vane performs two intake/dischsrge operations for every rotation of
the rotor. This means that the hydraulic fluid pressure pulse becomes extremely small during discharge.
CAM RING
FLOW CONTBOL VALVE
DRIVE
Operation
The belt-driven pulley rotates the rotor through the drive shaft, As the rotor rotates, the hydraulic pressure is applied to
the vane chamber of the rotor and the vanes witl rotate while being pushed onto the inner circumference of the cam .ing.
The inner circumference of the cam ring has an extonded portion with respect to the center of the shaft. so the rollers
move downward in the axial direction as the carrier rotates. As a result of this roller movemsnt, the internal volume of the
vane chamber will change, resulting in fluid intake and discharge.

System Description
Steering Pump (cont'dl
Flow Control
The flow control valve in the pump performs the follow-
ing steps @ through O to control the flow of fluid, i.e. to
increase the discharge volum€ wh6n 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 run through the metering
orifice in the pump. The discharge volume increas€s
as the engine speed increases,
As the flow has already been regulated by the
metering orifice when the engine speed is at or near
the idle speed, a constant and regulated amount ot
fluid is discharged until the engine speed reaches
the middle speed range. As the engine speed
increases, the pressure difference between the ends
of the metering orifice increases. A pressure differ-
ence is created between the top and bottom ends ofthe flow control valve, too, pushing the flow control
valve to open the by-pass passage. This allows the
excess fluid to return to the inlet pon preventing
pressure at the discharge port trom rising exces-
sively.
As the engine speed continues to increase, the tlow
control valve is pushed back further. When the
engine speed reaches a given speed. the return pas-
sage outside the metering orifice is connected to
the inlet port, and the opening to the inlet port
widens in proportion to the increase in engine
speed. This makes pan of the fluid regulated by the
metering orifice return to the inlet pon of the pump;
there by discharged fluid from the pump is
decreased slowly by this amount.
The orifice in the return passage regulates and
maintains the flow of fluid discharged from thepump at a given level until the engine speed reach-
es the high speed range.
