on a crankshaft you have a crank journal (more commonly called a main journal) and a rod journal. the main journals of the crankshaft are where and how the crankshaft is held in the block. the rod journals are where your connecting rods are attached to.

Why are crankshafts counterbalanced?
The weight of the piston, rings, and connecting rod is concentrated out at the rod journal. As the crank spins, it throws that weight around. The counterweight is on the opposite side from the rod journal to offset this weight. This is why when you replace pistons or rods, the crank is rebalanced by adding or removing material from the counterweight.

How do you remove babbitt from crankshaft?
I assume you mean the bearing lining from a stuck or spun bearing. You can have the crank turned at a machine shop, or you can use strips of emery cloth and polish it off. Use strips 12 to 18 inches long and as wide as the journal. Rotate the crank as far as you can to one side, the 8 or 9 o'clock position, put a strip of emery cloth over the journal and holding each end in a hand, polish the crank. Do this for a while and then rotate it to the 3-4 o'clock position and do the same. This should let you get to the entire journal.
What is Con rod bearing and main journal 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.

How long will a rod bearing repair last if I don't turn the crank?
It depends on how much damage was done to the crank. If the journal is smooth and mics out as still round and close to original specs it will last just as long as a crank that has been turned. If you actually spun a bearing then you can bet that the crank journal will no longer be round and putting a new bearing in won't last long at all. You can pick up a mic gauge really cheap at harbor freight. The cheap ones will be plastic....and though they aren't as good as the professional ones, they will take fairly accurate measurements.
What Would Happen if all oil exhausted?
Usually one of the rod bearings seizes to the crank, destroying it and the crank journal. If the engine is running hard, it can seize and explode, sending chunks of the rod and crank out the side of the engine. It is usually the rod that is furthest from the oil pump. In a Geo Metro, this will be cyl 3. -Carl
