23. Inspect the thin washer located on the armature for
cracks, etc., and security of mounting.
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.
24. 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.
25. Reassembly The Contactors. Install both coils onto
contactor base.
Terminal connections must point outward away from
center of base. Be certain the coils are properly located
over the base alignment pins.
26. Locate Brackets (3) on each coil and onto the base. Be
certain the bracket alignment pins properly seat in the
holes on the top side of each coil.
27. Now, secure the Forward Contactor Assembly Support
into the vice using minimum pressure to hold the
support.
Install spring into coil recess.
Locate white bushing over armature stem and insert
armature through bottom of support positioning
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.
