What is the purpose of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to spin smoothly while maintaining proper oil clearance.

Why would I need an undersize bearing set like this?

Undersize bearings, like this 0.050 inch set, are used when the crankshaft journals have been machined down to remove wear or damage. The bearing's undersize matches the machined journal size.

What material are these bearings made from?

This bearing set uses King's standard materials, which are chosen for their durability and ability to handle engine loads.

About this part

Product Details

If you're rebuilding the bottom end of your Holden 175/190 with the 3.6L engine, a fresh set of main bearings is crucial. These King Engine Bearings are designed to handle the loads and stresses within the crankcase, ensuring smooth rotation of your crankshaft.

This particular set is a 0.050 inch undersize, meaning it's intended for crankshafts that have been machined down by that amount to correct for wear or damage. King is known for making well-built bearings, and this set uses their standard materials and construction to provide reliable performance for your rebuild. They fit right into the main journals, providing the necessary clearance for oil film to cushion the rotating assembly.
