What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are larger than standard size by 0.75mm. This is necessary when the crankshaft journals have been machined undersize by 0.75mm during an engine rebuild to correct wear or damage.

What is trimetal material used in these bearings?

Trimetal is a well-built bearing material composed of three layers. It's known for its excellent load-carrying capacity and wear resistance, making it a popular choice for high-performance and heavy-duty engine applications like your Cummins diesel.

Do these bearings come with installation hardware?

This product listing is for the connecting rod bearings only. Installation hardware, such as new rod bolts, is typically sold separately and should be sourced according to your engine's service manual specifications.

About this part

Product Details

When you're rebuilding the bottom end of your Cummins 4BTA, 4Btaa, 6BT, or 6Bta engine, getting the right connecting rod bearings is crucial. This set from King Engine Bearings is specifically designed for these popular diesel engines and comes sized at +0.75mm, meaning they are 0.75mm larger than standard to accommodate crankshaft journals that have been machined to that size.

These bearings are constructed with a trimetal material, which is a well-built combination known for its strength and ability to handle the high loads and temperatures found in diesel applications. This material helps ensure proper oil film retention and wear resistance, which are vital for the longevity of your engine's rotating assembly. Having the correct bearing clearance is key to oil pressure and engine health, and these bearings are made to meet those needs when installed on a machined crankshaft.
