What does '0.030 undersize' mean for these bearings?

This means the bearings are manufactured to be 0.030 inches smaller in diameter than a standard-sized bearing. This size is typically used when the crankshaft journals have been machined down by 0.030 inches during an engine rebuild.

What is the main function of rod bearings?

Rod bearings are a critical component in your engine's rotating assembly. They sit between the connecting rod and the crankshaft, providing a low-friction surface that allows the crankshaft to spin smoothly while supporting the connecting rod's movement.

Are these bearings sold individually or as a set?

This product is sold as a set, containing all the necessary rod bearings for your Fiat 1.2L or 1.4L engine.

About this part

Product Details

This is a set of rod bearings from King Engine Bearings, sized 0.030 inch undersize. These bearings are crucial for the proper function of your Fiat's 1.2L or 1.4L engine. They sit between the connecting rod and the crankshaft, allowing the rotating assembly to spin smoothly while handling significant loads.

King Engine Bearings is known for making well-built engine components. This set is specifically manufactured to be 0.030 inches smaller than standard size, which is important when rebuilding an engine where the crankshaft journals may have been machined down to this size. Using the correct undersize bearing ensures a proper oil clearance, which is vital for lubrication and preventing premature wear.
