  Q: How to Service and Repair the Main Bearing Crankshaft Seal on Lincoln MKS?

  A: A proper crankshaft main bearing seal service and repair requires initial removal of the Oil Pan followed by careful cleaning procedures to avoid contamination of passages that might cause engine damage. A Heavy Duty Floor Crane combined with a Spreader Bar enables you to detach the engine from its stand. First remove the Crankshaft Position Sensor electrical connector while also unscrewing the bolt which holds the CKP sensor. The Crankshaft Rear Oil Seal Remover along with a Slide Hammer works to pull out the rear crankshaft seal before discarding it. Secure the crankshaft rear seal retainer using eight bolts before installing two M6 oil pan bolts into the threaded holes of the retainer (with finger-tightness) until the retainer seal can be removed. Apply rotational force one turn by one turn to the bolts until the retainer seal lets go and then remove the crankshaft rear seal retainer. Cleaning of the crankshaft rear seal retainer plate requires a 3M(TM) Roloc(R) Bristle Disk (2-in white, part number 07528) running at a speed of 15,000 rpm to wipe it down properly while removing all foreign materials. Engine cavities must receive protection from contamination by using clean lint-free shop towels while the technician removes them skillfully to stop accidental debris from entering the engine. Trustworthy sealing areas of the cylinder block need preparation through silicone removal of huge deposits followed by silicone gasket remover application and setting duration before cleaning. Additional application of the product might be needed to treat any remaining traces. Finish the surface preparation process through metal treatment to remove residual oil and coolant but avoid producing shine since some staining is natural.
