Alternator Overhaul
CAUTION: Do not r€move th€ pulley unl€Es the t.ontbearing needs r6placsm6nt.
To loosen the pulley locknut, use 10 mm and 22 mmwrenches. It necessary, use an impact wrench.

RectifierTest
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-
lion. Each diode must be tested for continuitv in both
directions with an ohmmeter that has diode checking
capability. Since the alternator rectifier is made up of
eight diodes (four pairs), there are a total of '16 checks,
1. Check for continuity in each ditection between the
B and P terminals, and between the E (ground) and
P terminals of each diode pair. All diodes should have
continuity in only one direction,
lf any of the eight diodes tails, replace the rectifier
assembly. (Diodes are not available separately.)
Gharging System
Alternator Brush Inspection
Remove the end cover, then lake oul the brush
holder by removing its two screws
Measure the length of the brushes with a vernier
calioer.
Aliornatol Brush Longlh:
Standard: 10.5 mm (O.41 in)
Servic. Limit: 1.5 mm (O.06 in)
lf the brushes are less than the service limit, replace
the b.ush holder assemblv.

Rotor Slip Ring Test
1 . Check thst there is continuity between thg slip rings.
ROTOR SHAFT
Check th8t there is no continuity betw€en the slip
rings and the rotor or rotor shaft.
lf the rotor fails either continuity check, rsplace th€
alternator.

Stator Test
1. Chock that there is continuity between each pair ofl6ads.
Ch6ck that there is no continuity between each lead
and the coil core.
lf th€ coil fsils either continuity check. replace the
alt6rnator.

Charging System
Alternator Belt Inspection and Adjustment
Deflection Method:
Apply a force of 100 N (1o kgt, 22 lbJ) and measure the
deflection between the alternator and the crankshatt
pulley.
Detlsction:9-11 mm (0.35-O.43 inl
NOTE; On a brand-new belt {one that has be€n run
for less than five minutes), the deJlection should be
6-8 mm 1O.23-O.32 in) wh€n first measured. lf
the belt is worn or damaged, replace it.

lf adiustment is nocessarY:
1. Loosen the alternator adjusting nut and mounting
nur.
2. Move the alternator to obtain the proper belt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the deflection ot the belt.
NOTE: lt necessary, adiust the P/S pump belt (see
section 17) and A/C compressor belt lsee section
22t.

Boh Tsnsion Gaug6 Mothod:
Foltowing the gauge manuJacturer's instructions, attach
the belt tension gauge to the belt and measure the
tension.
Tension: 340-49O N (35-50 kgl, 77-110 lbfl
NOTE: On a brand-new belt (one that has been run
for less than tive minutes), tension should be
690-880 N (70-90 kgt, 154- 198 lbJ) when tirst
measured. lf the belt is worn or damaged, replace it.
lf adi$tmsnt is nscaasary:
1. Loosen the alternator adiusting nut and mounting
nut.
2. Move ths ahernator to obtain the proper bslt tension,
then retighten the adjusting nut and mounting nut
to the specified torques.
3. Recheck the tension of the belt,
NOTE: lf necessary, adjust the P/S pump belt (see
section 17) and A/C compressor belt (see section
22t.
