About these Engine Bearings

The MAHLE ORIGINAL/CLEVITE M77CB743HN21 engine bearings are the precision shells the crankshaft and connecting rods run on, separated from the metal by a thin film of oil. Bearing condition and clearance are critical to oil pressure and engine life.

Frequently asked questions

What do rod and main bearings do?

Main bearings support the crankshaft in the engine block, and rod bearings sit between the connecting rods and the crankshaft. Pressurised oil keeps a film between the bearing and the journal so the metal surfaces never touch.

What are the signs of worn engine bearings?

A knocking noise that rises with engine speed, low oil pressure or an oil-pressure warning, and metal particles in the oil or filter. Worn bearings should be addressed immediately to avoid crankshaft damage.

Why do some engines get preventive bearing replacement?

Some high-performance engines are known for rod bearing wear, so owners replace the bearings preventively at a set mileage. Ask a specialist for your engine whether that applies.

Can I replace engine bearings myself?

It is precision engine work: bearings come in sizes that must match the crankshaft and block, and clearances must be measured during assembly. It is best done by an experienced engine builder with the correct tools and specifications.

How do I make sure this engine bearing set fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
