VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the specified lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric pres-
sure. So the vacuum pump lubricant may migrate out of the pump
into the service hose. This is possible when the pump is switched off
after evacuation (vacuuming) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as follows.
lUsually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
lFor pumps without an isolator, use a hose equipped with a man-
ual shut-off valve near the pump end. Close the valve to isolate
the hose from the pump.
lIf the hose has an automatic shut-off valve, disconnect the hose
from the pump. As long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2²-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified lubricants.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.

POWER STEERING FLUID
POWER STEERING FLUID
PFP:KLF20
Checking Fluid LevelEGS001LD
lCheck fluid level with engine stopped.
lMake sure that fluid level is between MIN and MAX.
lFluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
lThe fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
lDo not reuse drained power steering fluid.
lRecommended fluid is Type DEXRONTMIII or equivalent.
Checking Fluid LeakageEGS001LE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80°C(122
to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over-tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer toPS-25, "
POWER STEERING OIL
PUMP".
6. Check steering gear boots for accumulation of fluid, indicating from steering gear.
Air Bleeding Hydraulic SystemEGS001LF
If air bleeding is not complete, the following symptoms can be observed.
lBubbles are created in reservoir tank.
lClicking noise can be heard from oil pump.
lExcessive buzzing in the oil pump
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left to full right stop with engine off.
CAUTION:
Turn steering wheel while filling reservoir tank with fluid so as not to lower fluid level below the
MIN line.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and while contamination.HOT : Fluid temperature 50 - 80°C (122 - 176°F)
COLD : Fluid temperature 0 - 30°C(32-86°F)

ASSEMBLY
1. Apply recommended fluid to O-ring B. Put an O-ring B into a rack Teflon ring.
2. Heat rack Teflon ring to approximately 40°C(104°F) with a
dryer. Assemble it to mounting groove of rack assembly.
3. Install the Teflon ring correcting tool [SST: KV489Q0020] (A)
from tooth side of rack to fit rack Teflon ring (1) on rack. Com-
press the ring with tool.
4. Apply recommended grease to rack oil seal. And install rack oil
seal in the following procedure. Then assemble rack assembly
to gear housing assembly.
CAUTION:
lInstall rack oil seal in a direction so that the lip of inner oil
seal and the lip of outer oil seal face each other.
lDo not damage retainer sliding surface by rack assembly.
Replace gear housing assembly if damaged.
lDo not damage gear housing assembly inner wall by rack
assembly. Gear housing assembly must be replaced if
damaged because it may cause fluid leakage.
a. Wrap an OHP sheet [approximately 70 mm (2.76 in)´100 mm
(3.94 in)]. Around rack assembly teeth to avoid damaging rack
oil seal (inner). Install rack oil seal over sheet. Then, pull oil seal
along with OHP sheet until they pass rack assembly teeth, and
remove OHP sheet.

b. Insert rack oil seal (inner) into rack assembly piston (rack Teflon
ring).
c. Push retainer to adjusting screw side by hand, and move the
rack assembly inside the gear housing assembly so that the
rack oil seal (inner) can be pressed against the gear housing
assembly.
d. Wrap an OHP sheet [approximately 70 mm (2.76 in)´100 mm
(3.94 in)]. Around the edge to avoid damaging rack oil seal
(outer). Install rack oil seal over sheet. Then, pull oil seal along
