MICA DEPTH
Check the grooves of the commutator and measure the
mica depth [1].
SERVICE LIMIT: 0.5 mm (0.02 in)
If the grooves are clogged or mica depth is less than the
service limit, recut the grooves using a hacksaw blade
or a small file.
ARMATURE
Check for continuity between each segment.
If an open circuit exists between any two segments,
replace the armature.
Check for continuity between the commutator and
armature coil core.
If there is continuity, replace the armature.
Check for continuity between the commutator and
armature shaft.
If there is continuity, replace the armature.
