  Q: How to service and repair the crankshaft on Lincoln Town Car?

  A:

  You should start crankshaft servicing with two directional measures of each main bearing journal diameter. The journal diameters at both ends of the main bearing journal need to be measured in two different directions to evaluate out-of-round and taper conditions. Execute the clearance test between bearing and journal only when the main bearing journal crankshaft is operationally compliant. Lay a piece of Plastigage(R) across each crankshaft main bearing surface when those bearings and caps are removed and the crankshaft remains stationary. Check the crankshaft journal clearance after putting back the main bearing crankshaft cap and taking it out again. To measure crankshaft end play you should use a Dial Indicator Gauge by placing the crankshaft at cylinder block rear position then zeroing the indicator before moving the crankshaft to the front position to record the end play measurement. A Dial Indicator Gauge aids in checking crankshaft runout measurements by rotating the crankshaft followed by subtractions of the highest reading from the lowest reading when main bearing journal specifications are met. The wear limit for the connecting rod bearing journal taper and out-of-round should be met by measuring the diameters of the crankshaft connecting rod journal in two perpendicular directions at each end of the journal.
