    Q:
    What is the purpose of checking the endplay, and how is it measured for the 1989 Chevrolet Beretta? Posted by Customer
    A:
    The purpose of checking the endplay is to ensure the proper clearance between the connecting rod and the crankshaft. It is measured by sliding feeler gauges between the first connecting rod and the crankshaft throw until the play is removed. The endplay is equal to the thickness of the feeler gauge(s).

    Q:
    Why is it important to have the pistons available if the cylinder block requires machine work for the 1992 Oldsmobile Cutlass? Posted by Customer
    A:
    If the cylinder block requires any machine work, including finish honing, the machinist will want the pistons available to check piston-to-bore clearance as the cylinder walls are cut. This measurement is critical and is best left to the machine shop.

    Q:
    What should be done before forcing the piston assemblies up through the top of the engine block for the 1990 Oldsmobile Cutlass? Posted by Customer
    A:
    Before forcing the piston assemblies up, use a ridge reamer to eliminate the ridge or carbon deposits at the top of each cylinder.

    Q:
    What should be done after the piston is pushed into place for the 1989 Oldsmobile Cutlass? Posted by Customer

    Q:
    What should be done after removing the pistons from all cylinders for the 1990 Pontiac Grand Prix? Posted by Customer

    Why should you avoid touching the new bearing inserts with your fingers for the 1999 Pontiac Grand Prix? Posted by Customer

    You should avoid touching the new bearing inserts with your fingers to prevent contamination.

    Q:
    How is piston-to-rod clearance checked for the 1995 Pontiac Grand Prix? Posted by Customer
    A:
    Check piston-to-rod clearance by twisting the piston and rod in opposite directions. Noticeable play indicates excessive wear that requires correction.
