What does the '+0.75mm' size designation mean?

The '+0.75mm' indicates that these bearings are 0.75mm larger than the standard size. This is used when the crankshaft journals have been machined undersize by 0.75mm during an engine rebuild or repair.

What is the purpose of the specialized overlay material?

The specialized overlay material is designed to reduce friction and wear between the bearing and the crankshaft. This helps to improve the durability of the engine and ensure smooth operation.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings to complete the installation for the specified engine.

About this part

Product Details

This set includes the main bearings you need for a Holden Alloytec 175/190 engine rebuild. These bearings are sized at +0.75mm, meaning they are 0.75mm larger than standard to accommodate crankshaft journals that have been machined to that size. Proper bearing clearance is crucial for oil flow and engine longevity, ensuring the crankshaft spins smoothly within the engine block.

King Engine Bearings uses a specialized overlay material that is well-built for durability and performance. This overlay helps to reduce friction and wear, even under demanding operating conditions. The precise sizing and construction of these bearings are important for maintaining correct oil pressure and preventing premature engine failure.
