.P. D1075.tif97,5tiff;;
.D. ICON06.tif0,750,75tiff;; Inspect
Check for continuity between commutator segments, replace armature if no continuity.
.P. U2252.tif97,5tiff;;
.D. ICON06.tif0,750,75tiff;; Inspect

Check for no continuity between commutator and shaft, check also for no continuity between commutator and armature core, armature core and shaft.

.P. U2509.tif97,5tiff;;
.D. ICON06.tif0,750,75tiff;; Inspect

Commutator for wear.

Recut surface of commutator if necessary - turn at speed of 2000 - 3000 rpm.

Minimum diameter - 34 mm / 1.34 in.

Remove copper burrs from commutator after recutting.

.D. ICON11.tif0,750,75tiff;; Important!

Do not damage insulation.

If necessary smooth surface of commutator after removing burrs - use fine emery cloth (P500 - 600), then a buffing cloth.
.P. C7185.tif97,5tiff;;
.D. ICON07.tif0,750,75tiff;; Measure
