TM5-6115-593-34 NAVFAC P-8-631-34 TO-35C2-3-463-2 (3)   Secure   bypass   oil   filter   assembly   bracket   to engine with six screws. (4)   Attach bypass oil filter. (5)   Install  ether  lines  with  the  six  support  clamps and screws. 13-6. STARTER  ASSEMBLY  (Code  B)    To  service the     components     of     the     starter     assembly, proceed as follows: CAUTION Remove negative battery cable first and tape cable terminal. a. Removal.        Remove    starter    motor    by    removing battery    cable    connections    to    starter    and    three screws  which  secure  housing  (21,  figure  13-9)  to engine.  Tag and remove wires to the pilot relay (6, figure 13-4). b. Inspection.  Remove inspection plug (1, figure 13-9). If any brush is less than 3/8 inch (9.5 mm) long, the complete  set  of  brushes  should  be  replaced,  para. 13-6 d (21). c. Test.    Testing  of  the  starter  motor  and  electrical solenoid  assembly  consists  of  a  no-load  test  of  the complete unit followed by a pinion clearance check and adjustment.  Before conducting the no-load test, check   armature   for   freedom   of   rotation.      Use   a screwdriver to turn the pinion on the exposed drive assembly in the drive housing.  Tight bearings, bent armature   shaft,   or   a   loose   pole   shoe   screw   will cause  armature  binding.    If  armature  does  not  turn freely,   disassemble   the   unit.      If   armature   rotates freely, conduct the no load test before disassembling the motor. CAUTION Do not allow starter motor to operate more than 30  seconds.  Allow  it  to  cool  at  least  2  minutes before   reenergizing.   Overheating   will   damage motor. (1)   Connect the starter assembly as shown in figure 13-10 (2)   Use power supply to obtain 20v DC on voltmeter. (3)   Using  rpm  indicator  and  ammeter,  at  95  amps rpm should be at 5500.  At a maximum current draw of 120 amps rpm should be at 7500. (4)   To check pinion clearance connect as shown in figure 13-11. CAUTION To prevent overheating damage to windings, do   not   energize   hold-in   windings   longer than  30  seconds.    If  adjustment  cannot  be made  in  this  time,  disconnect  battery  and allow windings to cool . (5)   Energize  hold-in  windings  in  electrical  solenoid by connecting a 24V DC battery to the G and S terminals.  Momentarily  energize  pullin  windings by  flashing  a  jumper  lead  from  the  G  to  the MTR  terminal  ((A}  figure  13-11).    Do  not  leave jumper   lead   connected.   Hold-in   windings   will keep  solenoid  plunger  in  operating  position  as long  as  battery  is  connected  between  G  and  S terminals. (6)   Push drive assembly toward commutator end of starter    to    remove    slack.        Measure    pinion clearance ({B) figure 13-11). (7)   Turn plunger rod nut (10, figure 13-9) clockwise to   reduce   clearance   and   counterclockwise   to increase  clearance  as  necessary  to  achieve  a pinion clearance of 0.328 to 0.390 inches (8.33 to 9.9 mm).  Apply pressure on stud to prevent turning while adjusting. (8)   After completing adjustment, disconnect battery from G and S. d. Disassembly (1)   Remove  four  brush  inspection  plugs  (1,  figure 13-9) and gasket (2) from lever housing (3). Discard gasket. 13-12
