Ohmmeter INSPECTION
1. INSPECT COMMUTATOR FOR OPEN CIRCUIT
Continuity Using an ohmmeter, check that there is continuity between the
segments of the commutator.
If there is no continuity between any segment, replace the ar-
mature.
S00054
2. INSPECT COMMUTATOR FOR GROUND
(a) Using an ohmmeter, check that there is no continuity be-
tween the commutator and armature coil core.
If there is continuity, replace the armature.
(b) Check that the commutator for dirty and burm on surface.
If the surface is dirty or burnt, correct it with sandpaper (No.400)
No Continuity
or on a lathe.
S00055
3. INSPECT COMMUTATOR CIRCLE RUNOUT
(a) Place the commutator on V-blocks.
(b) Using a dial indicator, measure the circle runout.
Maximum circle runout: 0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a lathe.
S00056
4. INSPECT COMMUTATOR DIAMETER
Using vernier calipers, measure the commutator diameter.
Standard diameter: 35.0 mm (1.378 in.)
Minimum diameter: 34.0 mm (1.339 in.)
If the diameter is less than minimum, replace the armature.
S00057
5. INSPECT UNDERCUT DEPTH
Check that the undercut depth is clean and free of foreign mate-
rials. Smooth out the edge.
Standard undercut depth: 0.7 mm (0.028 in.)
Minimum undercut depth: 0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a
hacksaw blade.

STARTING (1GR-FE) - STARTER (2.0 kW)
6. INSPECT BRUSH
(a) Check the brushes length
Brush Holder (1) Using vernier calipers, measure the brush length.
Side
Standard length: 15.0 mm (0.591 in.)
Minimum length: 9.0 mm (0.354 in.)
If the length is less than minimum, replace the brush holder and
starter yoke.

7. INSPECT STARTER BRUSH HOLDER ASSY
(a) Check the blush holder insulation
(1) Using an ohmmeter, check that there is no continu-
ity between the positive (+) and negative (-) brush
holders.
If there is continuity, repair or replace the brush holder.
No continuity
A23178
(b) Check the brush spring load.
(1) Take a pull scale reading at the instant the brush
spring separates from the brush.
Standard spring load:
21.5 to 27.5 N (2.2 to 2.8 kgf, 4.8 to 6.2 lbf)
Brush Minimum spring load: 12.7 N (1.3 kgf, 2.9 lbf)
Spring If the spring load is less than the minimum, replace the brush
Brush holder.

8. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
Continuity lead wire and field coil brush lead.
If there is no continuity, replace the field frame.

ST-21
STARTING (1GR-FE) - STARTER (2.0 kW)
9. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Continuity Using an ohmmeter, check that there is continuity between the
field coil end and field frame.
If there is no continuity, repair or replace the field frame.
Ohmmeter
P00299
Ohmmeter 10. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, measure the resistance between shunt
coil terminals (A) and (B).
(A)
(B) Resistance: 1.5 to 1.9 at 20 ◦ Jabse Service Manual Search 2026 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
