Product Details

Every crankshaft depends on its main bearings — they’re the foundation that keeps the rotating assembly running true. When bearings wear down, you lose oil clearance, pressure drops, and damage creeps in fast. A fresh main bearing set is the fix that restores that critical support and protects your engine from costly failure.

This replacement main bearing set is built to OEM specifications for proper fit, oil clearance, and long service life. Precision-machined surfaces ensure smooth operation under heavy load, while durable materials hold up to the pounding of high-compression starts and long hours in the field. Install them during a rebuild and you give your engine the backbone it needs to run strong and steady.

Whether you’re keeping a hard-working diesel in a Case IH®, a John Deere®, or a Massey Ferguson® alive, new main bearings mean better oil pressure, smoother running, and longer life. It’s one of the most important pieces of any bottom-end rebuild — and it’s built here to get the job done.

As a family-owned company, Abilene Machine has been providing farmers with dependable agricultural replacement parts for over 40 years. Whether you need to make a repair or perform scheduled maintenance, you can depend on us to help keep your equipment in excellent condition. And if you have any questions, please do not hesitate to contact our knowledgeable sales staff. We have over 100 years of combined ag parts sales experience to assist you.
