TM   9-2920-243-34 CHAPTER   2 DIRECT   SUPPORT   AND   GENERAL   SUPPORT MAINTENANCE   INSTRUCTIONS Section  I.  REPAIR  PARTS,  SPECIAL  TOOLS  AND  EQUIPMENT 2-1.  Tools  and  Equipment Standard and commonly used tools and equip- ment  having  general  application  to  this  materiel are authorized for issue by Tables of Allowance (TA)  and  Tables  of  Organization  and  Equipment (TOE). 2-2. Special Tools and Equipment Special  tools  and  equipment  required  to  perform repair and rebuild operations contained in this manual are listed in appendix B. 2-3.  Repair  Parts Repair  parts  for  the  starter  assembly  are  listed  in appendix B    which    is    the    authority    for requisitioning  replacements. 2-4.  Improvised  Tools The  dimensional  detail  drawing  of  the  improvised brush spring lifter (fig. 2-1) applies only to direct and   general   support   shops   to   enable   these maintenance  organizations  to  fabricate  the  tools locally, if desired. This tool is of chief value to maintenance  organizations  engaged  in  rebuilding a  large  number  of  identical  components;  however, it is not essential for rebuild and is not available for  issue. Figure 2-1. Improvised brush spring lifter. Section   Il.   TROUBLESHOOTING 2-5.  General a. This  section  contains  troubleshooting  in- formation for locating and correcting most of the operating  troubles  which  may  develop  in  the starter.   Each   malfunction   for   an   individual component  is  followed  by  a  list  of  tests  or  in- spections   which   will   help   you   to   determine probable causes and corrective actions to take. You  should  perform  the  tests/inspections  and corrective actions in the order listed. b. This manual cannot list all malfunctions that may  occur,  nor  all  tests  or  inspections  and corrective  actions.  If  a  malfunction  is  not  listed  or is  not  corrected  by  listed  corrective  actions,  notify your  supervisor. c. Troubleshooting a disabled starter after it has been removed from the vehicle and/or engine consists of subjecting it to tests on a suitable test stand. Information pertaining to this testing is 2-6. Procedures After   the   starter   has   been   received   by   the maintenance  activity  for  preliminary  inspection, or  if  performance  of  the  starter  has  been  un- satisfactory due to unknown causes, it must be inspected  as  described  in  this  section.  When  the cause  for  failure  has  been  found,  the  starter should  be  disassembled  and  repaired  before proceeding  with  the  tests.  Additional  operational tests performed on a damaged starter would only increase  the  damage.  The  following  chart  lists  the common  malfunctions  that  might  be  encountered, their  probable  causes,  and  the  recommended corrective  action. NOTE Make certain that unusual noises are not produced by the test equipment used. contained  in  paragraphs  3-26  through  3-29. 2-1
