MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
6. MOTOR DRAWS HIGH CURRENT
Step 1. Check pump cartridge assembly for
binding. The field tube may be cocked on im-
peller housing. This would cause bearings to
bind on the armature shaft. Use a thin piece of
shim stock or fine paper to check for gaps. If
no gaps are found, proceed to Step 2.
If a gap is found, the motor was
not assembled properly. Motor
bearings are probably damaged.
Remove armature, field tube,
and impeller from impeller
housing (paragraphs 2-18 and
2-19). Inspect inside diameters
of motor bearings for chipping
or cracks per instructions and
illustrations in paragraphs 2-16
and 2-22. Measure bearing
bore diameters per inspection
procedure. Replace bearings
if damaged or not within
dimensions.
