Section 3 - Rocker Levers - Group 03 Rocker Lever - Magnetic Crack Inspection (3-04) M11 Page 3-15 Rocker Lever - Magnetic Crack Inspec- tion (3-04) Use coil magnetization with residual magnaglow to mag- netize the rocker levers. Magnetize the rocker levers in a coil of 300 to 500 am- peres. Visually inspect the levers for cracks. Cracks will appear as a solid bright line. Discard cracked levers. Use a demagnetizer to remove the magnetism. Use solvent to clean the rocker levers. Dry with com- pressed air.
