Description
When you start hearing that telltale knocking sound from deep in the engine, or notice oil pressure dropping after warm-up, your main bearings are crying for help. Engine bearings wear over time, and when they do, oversized replacement bearings are often the answer. This .010 undersized main bearing set gets your John Deere diesel running smooth and quiet again after the crankshaft’s been turned.
What You’re Getting
- Complete main bearing set with the right mix—off-center tabs on the upper halves, centered tabs on the lower halves for proper oil flow
- Precision-manufactured .010 undersized bearings that restore proper clearances after machine work
- Quality construction that stands up to diesel compression and high operating temperatures
- All the bearings you need in one kit—saves trips to the parts counter
Built for Real Farm Work
This bearing set fits the workhorse 6-cylinder diesel engines in John Deere’s lineup—the 381 CID, 404 CID, and 466 CID powerplants found in both turbocharged and naturally aspirated versions. These are the engines that powered countless hours of field work, from running combines through harvest to pulling heavy tillage equipment.
Made to Last
Engine main bearings take a beating—they carry the full weight of the crankshaft while handling combustion forces and oil pressure variations. These bearings are built with quality materials that handle the heat cycles and loads that farm engines see every day.
Good to Know
This is for engines that have had the crankshaft turned .010 undersized—make sure your machine work matches the bearing size. The locating tabs are positioned correctly for proper installation and oil flow. If you’re doing the work yourself, clean everything spotless and check your torque specs carefully. Main bearing work isn’t something you want to redo.
