Why do I need undersized bearings?

Undersized bearings, like this 0.25mm set, are used when the crankshaft journals have been machined down (ground) during an engine rebuild. The undersize on the bearing matches the undersize on the journal to restore the correct oil clearance.

What is oil clearance and why is it important?

Oil clearance is the small gap between the connecting rod journal and the bearing surface. This gap allows a thin film of oil to flow, lubricating and cooling the components. Too little clearance can lead to overheating and seizure, while too much can cause excessive wear and noise.

Does this set include bearings for all connecting rods?

This is a set of connecting rod bearings. For a V10 engine, which has ten cylinders, you would typically need two bearings per connecting rod (one on each side of the crank journal). This set is designed to cover all connecting rods for your engine.

About this part

Product Details

Doing an engine rebuild on your 1999 Ford F-350 Super Duty with the 6.8L V10? You'll need a solid set of connecting rod bearings to get everything running right. These bearings from ACL are designed to fit your specific application and help maintain the correct oil clearance between the crankshaft and connecting rod. Proper oil clearance is crucial for preventing metal-on-metal contact and ensuring the longevity of your engine.

This set is undersized by 0.25mm, which is important if you've had your crankshaft ground down during the rebuild process. Using the correct undersize bearing ensures that you get back to the factory-specified oil clearance, which is vital for proper lubrication and bearing life. ACL is a well-known name in engine bearings, and these are a well-built option for your V10.
