_______
DAMAGE TO THE PARTS COULD OCCUR.
(1) The steps that follow give instructions on the different types of marks which you can apply to the surface of a part.
(a) Electrolytic etch 1) The electrolysis procedure uses a stencil to make the
letters and numbers. 2) The marks made with this procedure are permanent. 3) If it is necessary, you can also use this procedure to make
temporary marks.
4) You can etch a surface with electrolysis on all surfaces of the part which do not touch and move against a different surface.
(b) Marks made with ink. 1) Letters and numbers are made when you apply ink to the surface of the part. 2) Inks used to make a mark on the surface can lightly etch the surface. 3) Make sure the ink does not cause damage to the surface of the part.
4) You can apply an ink mark to all surfaces of the part which do not touch and move against a different surface.
