Description
If you’re hearing knocking sounds from down in the crankcase or seeing metal shavings in your oil, worn main bearings are likely the culprit. Main bearings are what keep your crankshaft properly positioned and supported as it spins thousands of times per minute. When they wear out, you’ll get that unmistakable knock that means it’s time to shut down and rebuild before you crack the block or throw a rod.
What You’re Getting
- Complete set of main bearings for a full crankshaft rebuild
- Precision-manufactured to .010″ oversize for engines with machined crankshafts
- Quality construction that meets OEM specifications for proper fit and durability
- Everything needed for main bearing replacement during engine overhaul
Built for Real Farm Work
This bearing kit fits tractors that need main bearing replacement during engine rebuilds. The .010″ oversize specification means these are designed for crankshafts that have been machined to clean up wear or scoring. Whether you’re rebuilding a utility tractor engine for cultivating or overhauling a larger row-crop machine’s powerplant, proper main bearings are essential for long engine life.
Made to Last
Engine rebuilding isn’t something you want to do twice, so these bearings are built to handle the demanding conditions inside a working tractor engine. They’re manufactured to close tolerances and use materials that can withstand the heat, pressure, and constant rotation that comes with years of field work, loader operations, and PTO use.
Installation Notes
Main bearing replacement requires a complete engine teardown and is typically part of a full engine rebuild. Make sure your crankshaft has been properly machined to .010″ oversize before installing these bearings. Use proper torque specifications and bearing clearances – too tight and they’ll seize, too loose and you’ll get that knock back quickly.
