    Q:
    How to remove burrs from the crankshaft oil holes and check for damage? Posted by Customer
    A:
    Remove all burrs from the crankshaft oil holes with a stone, file or scraper, chamfering the oil holes to remove sharp edges that might gouge or scratch the new bearings. Clean the crankshaft with solvent and dry it with compressed air, if available. Be sure to clean the oil holes with a stiff brush and flush them with solvent. Wear eye protection when using compressed air. Check the main and connecting rod bearing journals for uneven wear, scoring, pits and cracks. Also, check the rest of the crankshaft for cracks and other damage. Rub a penny across each journal several times. If a journal picks up copper from the penny, it's too rough and must be reground. If the seals have worn grooves in the crankshaft journals, or if the seal journals are nicked or scratched, the new seal(s) will leak. The crankshaft should be magnafluxed to reveal hidden cracks-an automotive machine shop will handle the procedure. Using a micrometer, measure the diameter of the main and connecting rod journals and compare the results to the Specifications. By measuring the diameter at a number of points around each journal's circumference, you'll be able to determine whether or not the journal is out-of-round. Take the measurement at each end of the journal, near the crank throws, to determine if the journal is tapered. If the crankshaft journals are damaged, tapered, out-of-round or worn beyond the limits given in the Specifications, have the crankshaft reground by an automotive machine shop. Be sure to use the correct size bearing inserts if the crankshaft is reconditioned. Examine the main and rod bearing inserts.

    Q:
    What should you check on the main bearing caps before removing them for the 1989 Chevrolet C1500? Posted by Customer
    A:
    The main bearing caps should be checked to see if they're marked to indicate their locations. They should be numbered consecutively from the front of the engine to the rear. If they aren't marked, they should be marked with number stamping dies or a center punch.
