  Q: How to service and repair a crankshaft on Ford Explorer Sport Trac?

  A: The service and repair of the crankshaft starts by using at least two measurements to check the main bearing journal diameters across each crankshaft main bearing. Test both ends of the journal by taking diameter measurements according to the first step. Start by evaluating the journal-to-bearing clearance once all main bearing journals of the crankshaft meet their specifications. Following main bearing removal and main bearing cap replacement place Plastigage(R) across each bearing surface surface. Do not turn the crankshaft when marking the journal clearance because you must first mount and then unmount the main bearing cap. To check crankshaft end play measure with a Dial Indicator Gauge by first positioning the crankshaft at the rear of the cylinder block then zeroing the indicator before moving the crankshaft to the front for recording the end play measurement. The Dial Indicator Gauge determines the crankshaft runout by rotating the crankshaft and performing a reading difference between the highest and lowest points.
