3. Engine Idle Speed
A: MEASUREMENT
1) Before checking idle speed, check the following:
(1) Ensure that air cleaner element is free from
clogging, ignition timing is correct, spark plugs are in
good condition, and that hoses are connected properly.
(2) Ensure that malfunction indicator light (CHECK
ENGINE light) does not illuminate.
2) Warm-up the engine.
G2M0096
3) Connect Subaru Select Monitor or the OBD-II general
scan tool to data link connector.
CAUTION:
When connecting Subaru Select Monitor, turn ignition
switch to OFF.
4) Start the engine and measure engine speed.
NOTE:
Engine speed is indicated on Subaru Select Monitor by
selecting “MODE F04”.
G2M0097
NOTE:
When using the OBD-II general scan tool, carefully read
its operation manual.
When Subaru Select Monitor is not used, attach the
pickup sensor on tachometer (Secondary pickup type) to
#1 cylinder spark plug cord.
This ignition system provides simultaneous ignition for
#1 and #2 plugs. It must be noted that some tachometers
may register twice that of actual engine speed.

A: PRECAUTION
When servicing clutch system, pay attention to the follow-
ing items.
1. MECHANICAL APPLICATION TYPE
1) Check the routing of clutch cable for smoothness.
2) Excessive tightness or looseness of clutch cable have
a bad influence upon the cable durability.
3) Apply grease sufficiently to the connecting portion of
clutch pedal.
4) Apply grease sufficiently to the release lever portion.
5) Position clutch cable through the center of toe board
hole and route it smoothly. Adjustment is done by moving
the outer cable.
6) Make sure not to let the clutch chatter when starting
forward or rearward. If clutch chattering occurs, readjust so
that the bend of clutch outer cable becomes flatter.

3-1SPECIFICATIONS AND SERVICE DATA
1. Manual Transmission and Differential
C: LINE PRESSURE TEST
1. GENERAL
If the clutch or the brake band shows a sign of slippage or
shifting sensation is not correct, the line pressure should be
checked.
Excessive shocks during upshifting or shifting takes
place at a higher point than under normal circumstances,
may be due to the line pressure being too high.
Slippage or inability to operate the vehicle may, in most
cases, be due to loss of oil pressure for the operation of
the clutch, brake band or control valve.
G3M0869
1) Line pressure measurement (under no load)
CAUTION:
Before measuring line pressure, jack-up front
wheels (front-wheel-drive model) or all wheels (4-wheel
drive model).
Maintain temperature of ATF at approximately 50°C
(122°F) during measurement.
(ATF will reach the above temperature after idling the
engine for approximately 30 minutes with select lever
in“N”or“P”.)
G3M0869
2) Line pressure measurement (under heavy load)
CAUTION:
Before measuring line pressure, apply both foot and
parking brakes with all wheels chocked (Same as for
“stall”test conditions).
Measure line pressure when select lever is in“R”,
“2”with engine under stall conditions.
Measure line pressure within 5 seconds after shift-
ing the select lever to each position. (If line pressure
needs to be measured again, allow the engine to idle
and then stop. Wait for at least one minute before mea-
surement.)
Maintain the temperature of ATF at approximately
50°C (122°F) during measurement. (ATF will reach the
above temperature after idling the engine for approxi-
mately 30 minutes with the select lever in“N”or“P”.)

Removal
Using a sharp-edged, long rod, remove seal ring and
O-ring from rack piston.
CAUTION:
Be careful not to scratch outer surface of rack piston
and seal ring groove. A scratch may reduce the seal-
ing effect, resulting in faulty piston operation.
G4M0834
Installation
1) Wash clean rack piston.
2) Install O-ring and seal ring in groove on rack piston.
CAUTION:
Do not expand O-ring and seal ring more than nec-
essary.
To facilitate installation of seal ring, first position
one half of entire seal ring in groove. Then slowly posi-
tion the second half using a spatula, as shown.
G4M0835
3) Apply a coat of grease to inner surface of ST and insert
rack piston into it. Leave ST at least 10 minutes until seal
ring settles down in place.

Be careful not to scratch rack, piston and seal ring
during installation.
