This refers to the metal to metal damage caused by low oil pressure.
straightness, weight, cracksand journal wear
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.
Mains: 2.45" Rods: 2.10"
Just bought new rods with 2.10" journals
From the oil pump, through the block to the first main, then through the journal to the rods, then through the journal to the next main, ect.
A Vortec crank is a large journal, 350 ,one piece rear seal crank like all the millions of others. Two ten rods.
There are 5 main journals and 4 rod journals. Each rod journal holds 2 rods.
Connecting rod journals are the part of the crankshaft where the connecting rods attach to. There is one rod journal for each piston/connecting rod in the engine. These journals have a machined surface so the connecting rod bearings can move smoothly as the crankshaft rotates.
The standard crankshaft journal sizes for a Holden 304 are typically 2.5591 inches for the mains and 2.0866 inches for the rods. It's important to verify this information with a specific engine or consult the manufacturer's specifications for accuracy.
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.
Role scoring is when the critics score the role the actor is playing. Script scoring is scoring on the entire script.
There are old rods, good rods, and super rods, and super is the best.
