TM5-6115-593-34NAVFAC P-8-631-34TO-35C2-3-463-2(7) If field coils have electrical shorts, opens,grounds, oil soaking, or insulation obviously damagedbeyond repair, replace as follows:(a) Place a pole shoe spreader betweenopposite pole rotor shoes (67, figure 13-9)and tighten in place.(b) Using a pole shoe screwdriver and an arborpress, remove pole shoe screws (66).Remove pole screw spreader with pole rotorshoes (67).(c) Repeat steps (1) and (2) for other two rotorpole shoes.(d) Push in on field coil terminal stud (59) andslip field coils (64) out of starter housing (6).(e) Remove field coil insulators (63), insulatorplate (69), field terminal washer (62), andterminal bushings (65) and discard.(f)Insert new field coil (64) into starter housing(6) with new field coil insulators (63),insulator plate (69), field terminal washer(62), and terminal bushings (65).NOTEIf pole rotor shoes (67) have a long lipon one side, lip must face in directionof armature rotation (clockwise whenviewed from the drive end). Thislocates lip as trailing edge of polerotor shoe.(g) Insert pole rotor shoes (67) into position infield coils and retain with pole shoe screws(66). Do not tighten screws at this time.(h) Check that insulators (69) are properlyplaced and pole rotor shoes are not pinchingfield coils (64). Tighten pole shoe screws(66) using an ordinary screwdriver.(i)Place a pole shoe spreader betweenopposite pole rotor shoes (67) and tighten inplace.(j)Using a pole shoe screwdriver and an arborpress, tighten pole shoe screws (66) andremove pole shoe spreader.(k) Repeat steps (7) through (10) for other twopole shoes.(l)Ensure that terminal bushings (65) and fieldterminal washer (62) are properly positionedon terminal stud (59). Install another fieldterminal washer (62), flat washer (61), andplain hexagonal nut (41) on terminal stud.(m) Install terminal lug (60) and plain externalnut (40) on terminal stud (59). Do nottighten nut at this time.(8) Replace defective electrical holder assembly(44) and insulators as follows:(a) Remove brush plate screws (56) andelectrical holder assembly (44) with brushplate insulator (52) and insulator washer(47).Discard insulators if defective.(b) Install new brush plate insulator (52) andinsulator washer (47) on new electricalholder assembly (44) and insert stud13-19
