8. Secure support in a vice equipped with soft jaws using
minimum pressure to hold support.
9. Loosen and remove nut freeing core parts (washer,
insulators, movable contacts, spring seats and spring).
Note the position and location of each part for proper
reassembly. Remove these parts.
10. Remove armature core with spring from bottom of
support and remove support from vice.
11. Remove Bracket (3) from coil and base.
12. Remove coil from base.
13. Inspect all armature parts for cracks, breaks, etc. If parts
are found to be damaged, they should be replaced with
new ones.
Material on the armature stem has been “up set” in
four places to retain the washer. Inspect all four places
to be certain this thin washer is properly retained and
free to rotate about the armature stem.
Inspect the “cone” surface of the armature and the
corresponding surface in the base plate for scoring,
etc.
Inspect the small white bushing for wear. The bushing
I.D. must be perfectly round. If the bushing becomes
“egg” shaped (out-of-round), it should be replaced with
a new bushing.
14. Inspect coil for damage.
Inspect alignment holes to be certain they are perfectly
round and not “egg” shaped (damaged).
Inspect coil terminals for damage.
Replace damaged parts with new ones.
NOTE! The coil has four blind alignment holes in the
top and two in the bottom. These holes must
properly align with the off-set pins in the
bracket and contactor base at reassembly.
