October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Starter Component Inspection: Commutator
- Using "V" blocks and dial indicator, check commutator runout
(out-of-round). Ensure runout is not more than .002"(.05 mm). Turn
commutator/armature on lathe until runout (out-of-round) is within
specification.
- Check diameter commutator. Commutator should not be less than
specification. See MINIMUM
COMMUTATOR SPECIFICATIONS table. If commutator is cut down
more than .008" (.20 mm), undercut insulating mica to depth of
.015-.031" (.38 -.78 mm).
