Description
There’s nothing like the sound of a John Deere engine purring along, but when those main bearings start knocking, that smooth operation turns into something that makes your heart sink. If you’re hearing those telltale sounds during startup or under load, it’s time to get those worn bearings swapped out before you’re looking at a complete engine rebuild.
What You’re Getting
- Complete main bearing set with flanged thrust bearing for proper crankshaft support
- Standard size bearings that restore factory-spec clearances without machining
- Quality TISCO construction built to handle the demands of farm work
- Includes all bearings needed for one complete engine – no need to order parts separately
Built for Real Farm Work
This bearing set works in both 3-cylinder 135 CID gas engines and 4-cylinder 180 CID and 202 CID gas engines found in various John Deere tractors. These are the workhorses that power through hay season, cultivation, and all the daily chores around the farm. Whether you’re running a utility tractor or a row-crop machine, these engines see plenty of hours and deserve quality bearings.
Made to Last
Main bearings are the foundation of your engine’s bottom end, and cheap ones just don’t cut it when you need reliability. These TISCO bearings are manufactured to meet OEM specifications, with the proper materials and tolerances to handle the loads and heat cycles of agricultural work. The flanged thrust bearing keeps your crankshaft properly positioned under all operating conditions.
Good to Know
This is definitely an engine-out job that requires proper torque specs and measuring tools to do right. If your crankshaft journals are scored or out of spec, you’ll need machine work before installing new bearings. It’s worth checking rod bearings at the same time since you’ll have everything apart anyway.
