If you’ve ever rebuilt an engine, you know that every bearing matters – and thrust bearings are some of the most critical ones. These small half-moon shaped pieces control the crankshaft’s forward and backward movement in the engine block, preventing expensive damage from end play. When thrust bearings wear out, you’ll hear knocking, feel vibrations, and eventually face catastrophic engine failure if not addressed.
What You’re Getting
- Precision-machined bearings with 10 thousandths (.010″) thickness for proper clearance
- High-quality bearing material designed to handle the loads and speeds of diesel engines
- Exact OEM specifications that restore proper crankshaft positioning
- Set includes both upper and lower thrust bearing halves for complete replacement
Built for Hardworking Engines
These bearings fit the reliable 4045D, 4045T, 6068D, and 6068T Powertech engines found in a wide range of John Deere tractors from compact utility machines to larger row-crop models. Whether you’re running a 3000 series compact or a 7000 series row-crop tractor, these engines power through long days of loader work, cultivation, and heavy pulling.
Made to Last
Engine thrust bearings take a beating from the constant push and pull forces created by the crankshaft and clutch operation. These bearings are manufactured from specialized bearing alloy that provides excellent wear resistance while maintaining the oil film needed for proper lubrication. The precise thickness ensures proper clearance without being too tight or too loose.
Installation Notes
Always replace thrust bearings as a complete set and check crankshaft end play with a dial indicator during installation. Clean all surfaces thoroughly and use proper torque specifications when reassembling. If you’re doing a full rebuild, this is also a good time to check the main bearings and rod bearings for wear.
