TM   5-3895-360-13 9-2.   IGNITION  REPLACEMENT CLEANING AND INSPECTION a. b. c. d. e. f. WARNING (Con’t). Dry cleaning solvent, P-D-680, is toxic and flammable.  Always  wear  protective  goggles and gloves, and use only In a well-ventilated area.  Avoid  contact  with  skin,  eyes,  and clothes,  and  DO  NOT  breathe  vapors.  DO NOT use near open flame or excessive heat. The   solvent’s   flash   point   is   100°F-138°F (38°C-590C). If you become dizzy while us- ing cleaning solvent, Immediately get fresh air  and  medical  help.  If  solvent  contacts eyes, immediately wash your eyes and get medical aid. Compressed air used for cleaning or drying purposes, or for clearing restrictions, should never exceed 30 psi (207 kPa). Wear protec- tive  clothing  (goggleslshieid,  gloves,  etc.) and use caution to avoid injury to personnel. Clean flywheel and crankshaft with dry cleaning sol- vent (item 16, Appendix E) and dry with compressed air. Inspect flywheel for cracks and breaks. Replace fly- wheel if cracked or broken. Using a pencil (item 14, Appendix E), draw three ver- tical lines on tapered end of crankshaft approximate- ly 120° apart. Install flywheel on crankshaft and turn clockwise one full  turn.  Remove  flywheel. Inspect vertical lines on crankshaft. if 80% or more of the lines are rubbed off, contact is acceptable. NOTE Perform steps f through h only If flywheel con- tact is not within specification. Apply  an  even,  light  coat  of  lapping  compound (item 8, Appendix E) on crankshaft. 9-4 g. h. i. j. install flywheel on crankshaft and gentl`y rotate fly- wheel ¼ turn back and forth on crankshaft. Repeat every 90° until entire crankshaft has been covered. Remove  flywheel  from  crankshaft  and  wipe  lapping compound with clean rag (item 15, Appendix E). Using multimeter, test capacitor. Multimeter should show low resistance at first and then a quick rise to a high value. Replace capacitor if reading is not as specified. Using multimeter, test resistance of coil assembly. Resistance  reading  should  be  0.7-0.9  ohms.  Re- place coil assembly if reading is not within specifica- tion. INSTALLATION a. b. c. d. e. f. g. h. i. j. NOTE Refer to Figure 9-2, Stator Plate Replacement, for steps a through i. Install can (21) on crankshaft (20). install stator plate (23) on crankshaft support (6) with two  screws  (24). install cam (17). install contact set (26) on stator pi ate (23) with screw (27). Using  feeler  gage,  set  breaker  point  to  0.020  in. (0.508 mm). install coil assembly(19) and spring wedge (18) on stator plate (23). install capacitor (33) on stator plate (23) with screw (32). install two connectors (15 and 16), capacitor (33) and connector (13) on stator plate (23) with screw (22), new lockwasher (12), and nut (11). install capacitor wire lead (14) on connector (13). install new gasket (28) and cover (29) on stator plate (23) with breaker cover spring (25).
