Checking Solenoid Hold-In and Pull-InWindings (Code A)CAUTIONDo not leave pull-in winding energized for more than15seconds.(3) To check the pull-in winding, connect theother battery lead to the M terminal (shown in dotted line).(4) Adjust the voltage to 5 volts. Voltmetershall read 5V AC and ammeter shall read 10 to 11.5amps.TO-35C2-3-463-2(5) Replace switch if either winding isshorted or shows excessive resistance.j. Repair.Repair of the starter motor consists ofrepairing commutator bars whenever possible (if notbadly burnt) and replacement of parts found defectiveduring inspection. Repair commutator bars asfollows:(1) Using rosin flux, resolder or weld leads in theriser bars.(2) Turn down the commutator in a lathe.(3) Undercut and clean the commutator asindicated in paragraph k.k. Overhaul. Overhaul of the starter motor consists ofoverhauling the armature commutator andreplacement of parts found defective duringinspection. Overhaul the commutator as follows:(1) Turn down commutator in an appropriatelathe.(2) Undercut the insulation 1/32 of aninch wide and 1/32 of an inch deep.Remove any trace of dirt or copper dustbetween slots.(3) Sand the commutator lightly withNo. 00 sandpaper to remove any burrsresulting from the undercutting procedure.l. Assembly. Assemble the motor in accordance withfigure 13-4.(1) Install the pole shoes (91) and secure withpole shoe screws (90).(2) Install the armature (89) and field coil (99)in the housing (104).(3) Install the lever housing (37) with screws(26), and washers (27)..(4) Position the washer (34) and gasket (33) inthe lever housing and install the driveassembly (25) in13-10
