Clevite's Reputation in Engine Bearings
Clevite is one of the best-known names in engine bearings, used by engine rebuilders, machine shops, and performance builders alike. The brand is part of MAHLE's aftermarket lineup, and its catalog centers on the bearings that support the crankshaft, connecting rods, and camshaft, components that take heavy loads every time the engine fires.
Main, Rod, and Cam Bearings for Engine Rebuilds
Clevite's lineup includes main bearings, connecting rod bearings, camshaft bearings, and thrust washers, all found within our engine bearings category. Many bearings are offered in standard sizes as well as undersizes for crankshafts that have been ground, and some applications include performance-oriented options.
Shoppers typically come here during an engine rebuild or after finding low oil pressure, a deep knock that increases with load or RPM, metal particles in the oil, or a spun bearing. Knocks can also come from pistons, wrist pins, or the valvetrain, so accurate diagnosis, often with an oil pressure test and teardown, comes first.
Why Bearing Choice Affects Engine Life
Engine bearings ride on a thin film of pressurized oil. Their material, coating, wall thickness, and crush determine how well they hold that oil film, embed small debris, and handle heat. A bearing that doesn't match the journal size or clearance target can lead to low oil pressure or rapid wear. Compared with OEM bearings, quality aftermarket bearings are widely used in rebuilds partly because they're offered in the undersizes machine work often requires.
How to Choose the Right Clevite Bearing
Start with measurements. Have the crankshaft journals measured to determine whether standard or undersize bearings are needed, and confirm the target oil clearance with your machine shop or service manual. Note whether your build calls for a specific bearing series, especially for high-load or performance use. While the engine is apart, inspect the crankshaft and pistons, rings, and rods, and consider a new oil pump, since oil supply is critical to bearing life. Rebuilders often pair new bearings with a complete gasket set from Elring.
Matching Clevite Bearings to Your Engine
Bearing fitment depends on engine family, displacement, production year, and crank and rod design. Some engines changed bearing widths or locating tab positions during production. Select your vehicle, review product notes, and compare part numbers or measurements from the old bearings. Measuring clearance with a micrometer and bore gauge or plastigage is the safest way to confirm the fit. Follow torque specs from your service manual or a qualified machine shop.
Clevite Engine Bearing Questions
What does undersize mean on an engine bearing?
An undersize bearing is thicker so it fits a crankshaft journal that has been ground smaller. The size, such as .010", should match the machining that was done.
Can I replace rod bearings without removing the engine?
On some engines it's possible, but the journals can't be properly inspected or machined in the vehicle. Results depend on the engine and its condition.
Should main and rod bearings be replaced together?
In a full rebuild, yes. Replacing them together keeps clearances and wear consistent.
What causes a spun bearing?
Common causes include oil starvation, incorrect clearance, contaminated oil, and excessive load. Identify the cause before rebuilding.
