What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates these bearings are designed for use when the connecting rod journals on the crankshaft have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure a fresh, smooth surface for the bearings to operate on.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, a set includes all the bearings needed for the connecting rods on a specific engine.

What is the main function of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. They allow the connecting rod to pivot smoothly around the crankshaft journal while handling the high forces generated during combustion, preventing metal-on-metal contact.

About this part

Product Details

This is a set of connecting rod bearings from King Engine Bearings, specifically for the Datsun J15 engine. These bearings are sized at +0.25mm, meaning they are intended for use when the connecting rod journals have been machined down by 0.25mm during an engine rebuild. Connecting rod bearings are crucial components that sit between the crankshaft and the connecting rod, allowing the rod to pivot smoothly while handling immense forces.

King Engine Bearings is a well-known name in engine components, and this set is built to meet the demands of engine rebuilding. The +0.25mm sizing indicates these are replacement bearings for a specific machining operation, ensuring a proper fit and oil clearance after the crankshaft has been ground. Proper bearing clearance is essential for oil flow and preventing premature wear.
