Crankshaft Stress Cracks
A—Rod Journal Oil Holes
B—Journal Fillets
IMPORTANT: Small cracks may not be visible to the
eye. Use procedure such as the
Fluorescent Magnetic Particle method.
This method magnetizes the crank,
employing magnetic particles which are
fluorescent and glow under “black
light”. The crankshaft must be
de-magnetized after the test.
7. Carefully check the crankshaft for cracks in the area of
rod journal oil holes (A) and at journal fillets (B).
Replace crankshaft if any cracks are found.
