6G3-14 CRANKING SYSTEM
D Check commutator for uneven wear with armature supported on
1. Armature
2. V-block
V-blocks. If deflection of dial gauge pointer exceeds limit, repair
3. Magnetic stand
or replace.
4. Dial gauge
NOTE:
Below specification presupposes that armature is free from
bend. Bent shaft must be replaced.
Commutator out of round
Standard : 0.05 mm (0.002 in.) or less
Limit
D Inspect commutator for wear. If diameter is below limit, replace
armature.
Commutator outside diameter
Standard : 29.4 mm (1.16 in.)
Limit
D Inspect commutator for insulator depth. Correct or replace if be-
low limit.
Commutator insulator depth "a"
Standard : 0.4 – 0.6 mm (0.015 – 0.023 in.)
Limit
1. Commutator segment
2. Insulator
D Ground Test
Check commutator and armature core. If there is continuity, ar-
mature is grounded and must be replaced.
