Which tool(s) is best for oil clearance on crankshaft bearings?
The best tools for measuring oil clearance on crankshaft bearings are typically a micrometer and a dial indicator. A micrometer is used to measure the thickness of the bearing shell and the journal, while a dial indicator can help check for any runout or irregularities. Additionally, plastigage can be used as a quick and effective method to measure oil clearance by providing a visual indicator of the gap between the bearing and journal.
What is journal bearing?
That is another word for---The place on the crankshaft were the rod bearings are and were the crankshaft bearings are.
What is bearing clearance?
Bearing clearance is the distance between the crankshaft journal and the bearing surface. It is usually referred to as oil clearance, as that's what is occupying the space.
What is the crankshaft journal?
It's the place on the crank where the bearings ride.
What happens when rod bearings are to tight?
When rod bearing clearance is too tight the end result is what is called a spun bearing -- definitely a bad thing. Bearing clearance is the difference between the inside diameter of the bearing and the outside diameter of the crankshaft journal to which it is clamped. The bearing is supplied pressurized oil fed by the oil pump, it should never touch the crankshaft journal but should always float on a wedge of oil. If the clearance is too tight the bearing touches or drags on the crankshaft journal and the journal grabs the bearing and spins it inside the housing into which it is clamped -- which in the case of a rod bearing is the big end of the connecting rod. Once this happens it all pretty much self destructs as it chews up the big end of the connecting rod and the crankshaft journal as well.
Excessive copper in the engine oil?
The big-end shells (connecting rod to crankshaft) and crank shaft journal bearings have failed.
How is a bearing clearance measured in a main journal?
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),..
What are crankshaft journal clearance on a Chevy 350 engine?
I believe the clearance should be within .002 and .007 thousands of an inch. and also the end play clearance, should be between .002 and .007. you should check the bearing caps with plastic gauge, and the end play wiyh a feeler gauge.
What is a rod journal?
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.
What is crank journal?
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.

What is the size of Toyota 22re crankshaft main journal?
The main journal diameter of the Toyota 22RE crankshaft is typically 2.362 inches (60 mm). This measurement is crucial for ensuring proper fitment and function within the engine's main bearings. Always refer to a service manual for specific details and tolerances when working on this engine.
