Illustration 3 g06539857Illustration 3 shows the locations of the oil passages in the crankshaft. A borescope (T1) should be inserted from all entries into a passage.
Record the crankshaft serial number.
Borescope all drilled oil passages in the crankshaft journals, looking for burrs, or loose material.Note: Oil passages must be inspected from both directions to confirm whether an issue is present.
Main oil passages 2, 3, 5, and 6 have an angle in the middle of the passage which needs to be inspected from both directions.
Main oil passages 1, 4, and 7 are straight passages that need to be inspected from both directions.
