To measure the main bearing clearance on a four-stroke marine diesel engine, first, ensure the engine is cool and properly secured. Remove the oil pan and main bearing caps, then clean the bearing surfaces. Use a feeler gauge to measure the gap between the crankshaft and the bearing shell; insert the gauge at multiple points around the bearing to account for any uneven wear. Record the measurements to assess if they are within the manufacturer's specified tolerances for proper engine operation.
You should not need to remove the main bearing cap, in order to replace the rear main seal. The rear main seal will come off without touching the main bearing cap.
You can tell if the main thrust bearing is bad by simply checking out the oil. If you notice little metal particles, chances are the thrust bearing has spoiled.
