TM  S-6115-584-12 NAVFAC  P-6-622-12 TO-35C2-3-456-1 support bracket (12) down and away from starter. On Style  II  Starter,  support  bracket  is  not  fastened  to  the starter,  loosen  screw  (10),  Iockwasher  (11)  and  swing support  bracket  down  and  away. NOTE Support bracket and associated hard- ware must remain with engine at all times!  It  provides  support  for  Style  I Starters that may be used to replace Style II Starters during Operator and Organizational  maintenance.  The support  bracket  and  associated  hard- ware  is  supplied  on  all  engines manufactured with either the Style I or Style  II  Starters. Support starter (15) and remove screws (13), lock washers (14) attaching starter to flywheel housing (17). Slide starter out of housing. c.  Cleaning  and  Inspection  of  Starter  Brushes Solenoid  and  Drive. (1)  Cleaning  Starter.  Refer  to  paragraph 3-16a. (2)  Inspecting  Solenoid  Switch. (a) Style I Starter. Refer to figure 4-22. Inspect  solenoid  switch  (1)  for  cracks,  dents,  or  other physical  damage.  Check  to  see  that  the  electrical  ter- minals are clean and free of corrosion. Check that the rubber boot (2) on plunger (3), cotter pin (4), clevis pin (5), and yoke (6) are in good condition. Check that plunger (3) and yoke (6) operate freely. Check that so- lenoid switch (1) is securely fastened to the starter motor  (8),  with  screws  (14). (b)  Style  II  Starter.  Refer  to  figure  4-22A. Inspect  solenoid  switch  (3)  for  cracks,  dents,  or  other physical  damage.  Check  to  see  that  the  electrical  ter- minals are clean and free of corrosion. Check that solenoid switch (3) is securely fastened to the starter motor  (4),  with  screws  (1). (3) Inspecting Drive Assembly. Refer to fig- ure 4-22 for Style I Starter and figure 4-22A for Style II Starter. Inspect drive gear for cracks or chipped teeth. Check that gear and spring of drive moves freely, and returns  to  rear  position  when  released. (4) Inspecting Brushes. (a) Style I Starter. Refer to figure 4-21. Remove  two  through  bolts  (1)  and  lift  end  plate  (2) away from frame. Lift brush tension springs (3) and lift each brush (4) from holder for inspection. Check brush face  for  deep  surface  pits,  cracks,  or  excessive  chip- ping. Measure brush length. See figure 4-21. When brush is worn to length less than 1/4 inch, notify higher level maintenance for replacement of brushes (4). Clean area around brushes and commutator and dry with low pressure compressed air. Lift brush springs (3)  and  insert  brushes  (4)  in  brush  holder.  Reposition end plate (2) on frame and insert and tighten through bolts  (1)  securely. d.  Bench  Test. (1) Starter Assembly. Refer to paragraph 4-26a. (2)  Field  Coil.  Connect  continuity  tester  as shown In figure 4-19, Test c. An open circuit indicates a defective field coil. Test for continuity between field coil lead and field frame as shown in figure 4-19, Test d. Continuity indi- cates that the field coil is shorted to the field frame. (3)  Field  Coil.  Style  II  Starter. (a)  Connect  tester  for  continuity  between the field coil brushes as shown in figure 4-20, Test C. An open circuit indicates a defective field coil. (b)  Connect  tester  for  continuity  between afield brush and stator frame as shown in figure 4-20, Test D. Continuity indicates that the field coil is shorted to the frame. e. Repair. Style I Starter. (1)  Remove  Solenoid.  If  solenoid  is  defective, remove as follows: Refer to figure 4–22. Remove nut and Iockwasher holding lead (12) on small solenoid switch terminal. Remove nut and Iockwasher from negative terminal (9) freeing lead (12). Remove nut and  Iockwasher  from  solenoid  field  terminal  (11).  Re- move cotter pin (4) and clevis pin (5) from plunger (3) and yoke (6). Remove screws (14) and lift solenoid switch (1) from frame (8). Retain hardware from termi- nals  for  solenoid  installation. 4-28 Change 10
