How can you measure bearing?
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.

How do you replace the main bearing on a 2510 kawasaki mule?
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).

The flat spots on a crank are called journals. There are main caps with bearings both sides that hold the crank in the block. The conn rods have similar bearings & they also attach to crank journals. The bearings are c-shaped copper things that go in the conn rod & main caps for the crank.
