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.
The main journal radius, rod journal radius or otherwise both are known as the fillet.

bearing clearence is measured using the venier callipers.you join the 2 shells to form a circle then measure the inward diameter using your venier and likewise measure your crankshaft main journal oval diameter then subtract the main journal diamterfrom shell diameter/.OR you simply put the crankshaft into its position and put the other bearing cap and measure using a filler gauge (make sure both caps have their shell bearings),..
It's between the transmission and engine bodies, going around the crankshaft.
the number bolts per main cap on a crankshaft journal cap. a 4 is stronger than a 2
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.
The job of the rear main seal is to keep the oil lubricating the rear main bearing from leaking out. Older model rear main seals were made from a "rope" type of material. Today the rear main seal is a one or two piece seal made from neoprene rubber and is located directly behind the rearmost main bearing journal of the crankshaft.
The main bearings support the crankshaft.
I think they are one. Harmonic balancers usually are integrated as the main driving pulley in a serpentine system. Call a toyota parts department (dealer) to make sure.
