What is the main purpose of these main bearings?

These main bearings support the crankshaft within the engine block. They create a precise gap for oil to flow, which lubricates and cools the crankshaft as it spins, reducing friction and wear.

What is the material composition of these bearings?

The bearings feature a multi-layer construction. This includes a strong steel backing, a durable bronze-aluminum alloy overlay, and a thin babbitt overlay for excellent conformability and embeddability.

Are these bearings a direct replacement for original equipment?

Yes, these Clevite main bearings are designed as a direct replacement for the original equipment in specified air-cooled Volkswagen models. They are manufactured to precise tolerances to ensure a proper fit.

Product Details

If you're rebuilding the bottom end of your air-cooled Volkswagen engine, a fresh set of main bearings is critical. These Clevite MS1053A30 main bearings are designed to replace the original equipment, ensuring proper crankshaft support and oil clearance. They fit a wide range of classic air-cooled VWs, including models like the Beetle, Karmann Ghia, and Transporter.

These bearings are built with a multi-layer material that includes a steel backing for strength, a bronze-aluminum alloy overlay for durability, and a thin overlay of babbitt for excellent conformability and embeddability. This construction helps maintain consistent oil film thickness, which is vital for reducing friction and wear in these air-cooled engines. They are manufactured to precise tolerances to ensure they fit right and perform as expected.

When installing these bearings, it's important to ensure your crankshaft journals are clean and within factory specifications for size and finish. Proper oil clearance is key to the longevity of your engine rebuild.
