What is the primary benefit of the tri-metal construction in these bearings?

The tri-metal construction combines steel for strength, a lead-indium layer for conformability to the crankshaft journal, and a tin-bronze layer for wear resistance. This layered approach helps the bearings withstand high loads and maintain proper oil clearance.

Are these bearings a direct replacement for the original equipment?

These main bearings are designed as a direct replacement for Holden Alloytec 175/190 engines. They are engineered to meet or exceed the specifications of the original equipment for a proper fit and function.

What is the importance of proper oil clearance for crankshaft bearings?

Proper oil clearance is essential for engine health. It allows a thin film of oil to surround the bearing and crankshaft journal, reducing friction and wear. Too little clearance can lead to seizure, while too much can cause excessive noise and reduced oil pressure.
