Subaru Legacy IV (2008 year). Manual - part 97

SC(H4SO)-12

Starter

STARTING/CHARGING SYSTEMS

11) Install the magnet switch assembly to the start-
er housing, and tighten the nuts.

NOTE:
Apply grease to the installation part of the shift le-
ver.

Grease:

DENSO HL50

Tightening torque:

7.5 N·m (0.8 kgf-m, 5.5 ft-lb)

12) Install the harness to the terminal M (A) of the
magnet switch assembly, and tighten the nut.

Tightening torque:

10 N·m (1.0 kgf-m, 7.4 ft-lb)

E: INSPECTION

1. SWITCH ASSEMBLY

Using a circuit tester (set to “ohm”), check that
there is continuity between terminals S and M, and
between terminal S and ground.
Also check to be sure there is no continuity be-
tween terminal M and B.

Terminal/Resistance:

S — M/1

or less

S — Ground/1

or less

M — B/1 M

or more

2. SWITCH ASSEMBLY OPERATION

NOTE:
Test period of each test must be within short time (3
— 5 seconds).
1) Vacuum test
Disconnect the harness from terminal M and con-
nect it as shown in the figure. Make sure the pinion
gear sticks out.

2) Hold test
Make sure the pinion gear remains stick out even
after disconnecting terminal M in the above condi-
tion.

3) Return test
Connect the positive terminal to terminal S and the
negative terminal to terminal M and starter body to
pull the pinion gear at the main contact point. Make
sure the pinion gear returns to its original position
when the terminal S is disconnected.

3. PERFORMANCE TEST

The starter should be submitted to performance tests
whenever it has been overhauled, to assure its satis-
factory performance when installed on the engine.
Three performance tests, no-load test, load test,
and lock test, are presented here; however, if the
load test and lock test cannot be performed, carry
out at least the no-load test.
For these performance tests, use the circuit shown
in figure.

1) No-load test
With switch on, adjust the variable resistance until
the voltage is 11 V, read the value of ammeter to
measure rotating speed. Compare these values
with the standard.

No-load test (standard):

Voltage/Current

Max. 11 V/90 A or less

Rotating speed

1,900 rpm or more

2) Load test
Apply the specified braking torque to starter. The
condition is satisfactory if the current draw and ro-
tating speed are within specifications.

Load test (standard):

Voltage/Load

8 V/11.1 N·m (1.1 kgf-m, 8.2 ft-lb)

Current/Speed

370 A/910 rpm or more

3) Lock test
With the starter stalled, or not rotating, measure the
torque developed and current draw when the volt-
age is adjusted to standard voltage.

Lock test (standard):

Voltage/Current

3 V/750 A or less

Torque

15.5 N·m (1.6 kgf-m, 11.4 ft-lb)

C: DISASSEMBLY

1) Remove the four through-bolts.

2) Use a drier to heat the rear cover (A) portion to
50°C (122°F).

3) Insert the end of a flat tip screwdriver into the
gap between stator core and front cover. Pry them
apart to disassemble.

4) Using a vise, support the rotor and remove the
pulley bolt.

CAUTION:
When holding the rotor with a vise, place alumi-
num plates or wooden pieces on the vise jaws
to prevent rotor from damage.

5) Use the following procedures to remove the ball
bearings.

(1) Remove the bolt, and then detach the bear-
ing retainer.

(2) Firmly attach an appropriate tool (such as a
correct size socket wrench) to the bearing inner
race.

(3) Use the press to push the ball bearings out
from the front cover.
