Crankshaft Magnetic Crack Inspection (1-07) Section 1 - Cylinder Block - Group 01 M11 Page 1-30 Measure the rear oil seal flange outside diameter. Crankshaft Rear Oil Seal Flange O.D. mm in 164.965 MIN 6.4947 165.035 MAX 6.4974 Measure the damper pilot outside diameter. Crankshaft Damper Pilot O.D. mm in 32.01 MIN 1.2602 32.04 MAX 1.2614 Use clean 15W-40 oil to coat the entire crankshaft to prevent rust. Crankshaft Magnetic Crack Inspection (1-07) The crankshaft must be tested by the ’Continuous Method’. The entire surface must be wetted with the magnetic bath solution before and during the flow of the magnetic current through the crankshaft.
Head Shot (Longitudinal Magnetization) Apply the magnetic bath solution to the crankshaft and use 3800 amperes with direct current or rectified A.C. to magnetize the crankshaft.
