    When can the crankshaft be removed for the 2003 Ford Ranger? Posted by Customer

    Q:
    What can be used if a dial indicator isn't available to check the endplay for the 2006 Ford Ranger? Posted by Customer
    A:
    If a dial indicator isn't available, feeler gauges can be used. Gently pry or push the crankshaft all the way to the front of the engine. Slip feeler gauges between the crankshaft and the front face of the thrust main bearing (number 3 bearing) to determine the clearance.

    Q:
    How can the condition of the journals be assessed for the 2004 Ford Ranger? Posted by Customer
    A:
    Rub a penny across each journal several times. If copper rubs off and is embedded in the crankshaft, the journals should be reground. If a journal picks up copper from the penny, it indicates that it is too rough and must be reground.

    Q:
    How should the bearing faces in the block be prepared for the 2001 Ford Explorer Sport Trac? Posted by Customer
    A:
    Clean the bearing faces in the block, then apply a thin, uniform layer of moly-based engine assembly lubricant to each of the bearing surfaces.

    Q:
    How should the crankshaft be removed from the engine for the 2005 Ford Explorer Sport Trac? Posted by Customer
    A:
    Carefully lift the crankshaft out of the engine. It may be a good idea to have an assistant available, since the crankshaft is quite heavy. With the bearing inserts in place in the engine block and main bearing caps, return the caps to their respective locations on the engine block and tighten the bolts finger tight.

    Q:
    What should be done if the crankshaft journals are damaged or worn for the 2005 Ford Explorer Sport Trac? Posted by Customer
    A:
    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.
