ARMY TM 9-6115-464-34AIR FORCE TO 36C2-3-445-2NAVY NAVFAC P-8-624-34f. Assembly.(1) Assemble starter and solenoid in reverse order of disassembly procedures using new gaskets ando-rings. Inspect all insulating washers and bushings. Replace if defective.(2) If brushes were replaced, run in new brushes as follows:(a) Cover armature commutator with a piece of No. 00 grit sandpaper.(b) Temporarily install brushes and commutator end frame and run in brushes.(c) Disassemble, remove sandpaper, and clean armature commutator and brushholder assembly withfiltered compressed air.g. Testing.(1) Test starter solenoid assembly as follows:(a) Remove connector (14, Figure 3-4).(b) Apply 24 Vdc between the negative terminal and the small terminal of the solenoid assembly.(c) Solenoid actuation will be indicated by an audible “click” and rearward movement of the drive gear.(d) Remove 24 Vdc from solenoid assembly terminals.(e) The drive gear should move forward with an audible click.(f) Replace solenoid assembly if it fails to function properly.(g) Install connector.(2) Conduct starter assembly motoring test as follows:(a) Remove connector (14, Figure 3-4).(b) Install starter assembly into motoring test circuit shown in figure 3-2.(c) Adjust rheostat until voltmeter indicates 22.5 volts.(d) Check indications of ammeter and tachometer.(e) Ammeter should indicate 58 amperes maximum with starter turning at 9300 rpm.(f) If current and speed are low, disassemble starter and check for high resistance at internalconnection.(g) If current is high and rpm low, disassemble and inspect armature shaft and bushings for wear ormisalignment.(h) Do not install connector (14, Figure 3-4) until stalled torque test is completed.(3) Conduct starter assembly stalled torque, test as follows:CAUTIONRheostat must have a minimum capacity of 1000 amperes. Failure to observe thiscaution could result in equipment damage.(a) Install starter assembly in test setup shown in figure 3-3.(b) Adjust rheostat until voltmeter indicates 14 Vdc.3-14
ARMY TM 9-6115-464-34AIR FORCE TO 35C2-3-445-2NAVY NAVFAC P-8-624-34(c) Ammeter should indicate 540 amperes maximum at a minimum torque of 26 ft-lb indicated onscale.(d) If both current and torque are low, disassemble the starter and check for poor internal connectionsor improper brush contact. Both of these conditions would result in high internal resistance.(e) High current and low torque may be caused by defective armature or field coil assembly.(f) Remove starter assembly from test setup and install connector (14, Figure 3-4).h. Installation. Refer to the Operator and Unit Maintenance Manual for starter installation procedures.3-6. BATTERY CHARGING ALTERNATOR.a. Removal. Refer to the Operator and Unit Maintenance Manual for battery charging alternator removalprocedures.b. Disassemblv.(1) Remove screws (1, figure 3-5) and carefully pull regulator and cover assembly (2) away fromalternator.(2) Tag and disconnect electrical leads to completely separate regulator and cover assembly fromalternator.(3) Unsolder blue and brown leads from fuse holder (3). Remove nut (4), fuse holder (3) and washer (5)from cover assembly (2).(4) Remove fuse holder cap (6) and fuse (7).(5) Remove screws (8) and cover band (9).(6) Remove thru bolts (10) and remove head assembly (11).(7) Remove nuts (12 and 13), Iockwasher (14) and lead (15).(8) Remove screws (16), Iockwashers (17), insulating plate (18), brushholder (19) and brush and springassembly (20).(9) Remove nuts (21, 22, and 23), Iockwasher (24), screw (25) and flat washers (26) to removecapacitor and clamp assembly (27).NOTEIf capacitor and clamp assembly (28) was not removed and tagged when performingstep 3-6b. (2) above, remove and tag at this time.(10) Remove nuts (29 and 30), flat washers (31, 32,33 and 34). Remove rear part of insulating bushings(36, 37,38, and 39), and remove rectifier and stator assembly (40) from head assembly (11).(11) Unsolder leads and remove negative plate and rectifier assembly (41) and positive plate and rectifierassembly (42) from stator (43). Remove front part of insulating bushings (36, 37, 38 and 39) andstuds (35).(12) Clamp pulley in a soft-jawed vise and remove nut (44).(13) Remove assembly from vise and remove pulley (45) and fan (46).NOTEUse of a puller maybe necessary if pulley sticks to rotor shaft.3-15
