Cleaning and Inspection

CAUTION:
Handle the crankshaft (6303) carefully to avoid damage to the finished surfaces.

CLEANING
- Clean the crankshaft (6303) with hot or cold commercial tank solutions, solvents and brushing, or by steam cleaning. Be sure to clean the drilled oil passages that connect the main and connecting journals.
- Blow out all oil passages with compressed air.

INSPECTION
After cleaning, the crankshaft must be inspected to determine if it should be reused, reconditioned, or replaced. If the crankshaft has been subjected to or will be subjected to high-stress operation, consider a magnetic inspection of the crankshaft for cracks that cannot be seen with the eye. This service is available through most automotive machine shops.
- Inspect the main and connecting rod journals for cracks, scratches, grooves, scores or rough finish.
- Inspect the crankshaft rear oil seal surface for nicks, sharp edges or burrs that might damage the oil seal during installation or cause premature oil seal wear.
