Fluorescent  Penetrant  Inspection
TM   5-4210-233-14&P-1 4-9.  GENERAL MAINTENANCE PROCEDURES- Continued (4) Abrasive  Wear.    This  damage  is  caused  by  fine  particles  carried  in  the  lubricant  or  embedded  in  gear tooth.  This material may come from: Bearing or gear tooth material. Abrasives not removed during assembly. Sand or scale from castings. Impurities from oil or the environment. (5) Scoring. Slight scoring, galling or other surface damage is seen as tears or scratches in the direction of sliding. It starts in areas of highest stress and speed. This is usually at tip of teeth. (6) Burning. Burning is seen as discoloration, and causes loss of hardness of the metal. Burning is caused by any of the following: Gear Overload Overspeed Lack of Backlash Too Little Lubrication Wrong Lubricant If  discoloration  can  be  wiped  off,  such  marks  can  usually  be  traced  to  oil-burn  stains  which  are  not serious. (7) Rolling.  This  damage  usually  occurs  only  on  plastic  gears.  Rolling  is  when  material  is  pushed  out  of shape but does not break off.  It is usually caused by heavy, even loads and overheating. h.  Metal Parts.  Visually inspect all castings and weldments for cracks. Parts that carry a great load should be inspected   by   the   magnetic   particle   method.   Non-ferrous   parts   may   be   inspected   by   the   fluorescent penetrant method. i.     Magnetic  Particle  Inspection.    This  type  of  inspection  can  only  be  carried  out  on  metals  that  can  be magnetized. If in doubt check whether a magnet sticks to the surface. It should only be carried out it parts are  not  easily  replaceable  (cost  or  special  order),  or  parts  have  been  reworked  or  reground,  or  parts  are subject  to  high  stress.  Magnetizing  current  depends  on  parts  being  magnetized.  For  solid  section  parts, current shall be 1000 amps per diameter-inch. For variable diameter thickness, current shall be adjusted for diameter inspected. Parts shall be rejected if: (1) Indications  of  non-metallic  inclusions  are  present  (foreign  body-solid,  liquid,  or  gaseous)  and  these  are longer than one inch, or indications are closer than 1/8 in. apart. (2) Any evidence of cracks are seen. 4-151
