Engine Bearing Technology - The Spin on Spun Bearings

The damage is usually limited to the main journal surface on the crank and the main bore housing. A spun cam bearing will tear up the bearing bore in the block (or head in the case of an OHC cam), and possibly snap a timing belt or chain – which may result in one or more bent valves if it’s an interference engine.

Clearing the Air on Bearing Clearances

Aluminum blocks expand more than iron blocks, so many engine builders will tighten up the main bearing clearance when building the engine at room temperature, knowing that when the engine attains operating temperature, the clearance will have expanded.

Bearing Clearances - Engine Builder Magazine

The clearance is measured 90 degrees to the bearing parting line, which is the thickest part of the bearing (bearing thickness tapers slightly toward the parting line). Reducing the oil clearance between the rod and main bearings and the crankshaft has a number of advantages.

Main Bearing Clearance on Aluminum Block - Don Terrill’s

Main bearing clearance in an aluminum block is not critical, use the same clearances that you would use with a cast iron block. What is important though is the housing bore dimension. Aim for the minimum bore diameter, or very close to it.

EngineLabs' Blueprint Series: The Keys to Proper Block Align

If the block’s main saddles are not aligned, this only makes the main bearings’ life even more tenuous. When a factory or aftermarket block is cast, the main bearing holes are bored and finished to create both the proper housing bore inside diameter (I.D.) and alignment. In a perfect world, these main bores are all perfectly round and aligned.

Bearing Clearance and Oil Viscosity Explained

A bearing’s load carrying capacity is directly affected by clearance. As the clearance is tightened, load carrying capacity increases. As a generalized statement, 0.001-inch clearance offers a higher load carrying capacity than 0.002-inch using the standard 2.45-inch small-block main journal size as the example.

How to Check for Bad Main Bearings | It Still Runs

Main bearing sleeves come in two half-moon sections, one that sits inside the main bearing cap and one that sits in the engine block. The crankshaft journal spins within the two. The main bearings have oil holes that lubricate the journal. Main bearings can wear with normal age, or become pitted and galled with insufficient lubrication.
