.0010" to .0020" oil clearance
the clearance is measured at the top of the bearing with the help of a feeler gauge
The main bearing and rod bearinging clearance is usually in the manual. However, if worse comes to worse, you can find it on your rods in the truck.
The 1995 Toyota 3.0 liter engine main bearing torque specification is 160 pounds. The rod bearings torque specification is 120 pounds.
The Kia 2.5 liter engine main bearing torque specification is 180 pounds. The main bearings should be torqued in 60 pound intervals.
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.
Oil clearence is .0008--.0015 and # 2 and 4 mains are .0011--.0023
Perhaps excess bearing clearance?

A main bearing bore refers to the cylindrical opening in an engine block where the main bearings are housed. These bearings support the crankshaft and allow it to rotate smoothly, reducing friction and wear. The bore's size and precision are critical for engine performance, as they affect the alignment and clearance of the crankshaft. Proper maintenance and machining of the main bearing bore are essential for the longevity and efficiency of the engine.
The 1996 Dodge Intrepid main bearing torque specification is 180 pounds. The main bearings should be torqued in 60 pound intervals.
.0010 - .0022 in or .025 - .055 mm max limit is .0031 in or .08 mm
There is only one main bearing. It is on the flywheel side and is a plane bearing (not a ball or needle bearing). You have to remove the crankshaft, press the old bearing out and press the new one in. Once the new one is installed, it MUST be checked for proper oil clearance. If it's not correct (tight), it will lock and destroy the rest of the engine. There is only one main bearing. It is on the flywheel side and is a plane bearing (not a ball or needle bearing).
