do not rotate crankshaft
On the main bearings, .001, to .003.
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.
main bearing whats happens when goin out
It depends on the type of bearing, and which measurement. A double race roller bearing is measured on the inside (shaft diameter) with an internal vernier caliper or similar device. On the outside (casing or pillow block diameter) with an external vernier. And the width (or length) of each race can be measured with and external vernier. A babbitt bearing can be measured by measuring the journal on which it is to be mounted, then taking "leads" (or using plastigages), by placing lead fuse wire or a plastigage on the journal, placing the bearing top half over the leads, and bolting down the bearing housing over that. Then unbolt the bearing housing remove the top half the bearing and with a micrometer measure the crushed thickness of the fuse wire. Add this to the journal diameter to get the internal diameter of the bearing. The main reason for taking leads is to determine the oil wedge gap in the bearing to see if it is the right thickness. If it is too thin the bearing needs to be scraped if it is too thick the bearing needs to be replaced or the journal built back up to the correct diameter.
The rod bearing torque spec from mercruiser is 45 lb there is no spec that i can find for the main bearing caps.
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.
the torque setting for the the main bearings of the Toyota 2c engine is 103 Nm. The rid bearing caps are 59 Nm

Don't understand your question...... If you mean the rear main bearing in the engine ... then NO.
The thrust bearing is located in the crankshaft journal. usually in the center main cap. Although sometimes toward the front or rear it is recognizable, the only main bearing with sides.
