Description

When you’re hearing that telltale knocking from deep inside your engine or noticing that oil pressure just isn’t what it used to be, chances are your main bearings are telling you they’ve had enough. This oversize bearing kit gives your tractor’s engine a new lease on life, bringing back that quiet, smooth operation and proper oil pressure that keeps everything running right.

What You’re Getting

  • Complete set of main bearings sized .254 oversize for proper fit on reground crankshafts
  • Precision-manufactured bearings designed to handle the heavy loads and long hours of farm work
  • Quality materials that provide proper oil clearance and heat dissipation
  • Everything needed for a complete main bearing replacement during engine rebuild

Built for Real Farm Work

This bearing kit is designed for agricultural diesel engines that have been rebuilt with a reground crankshaft. Whether you’re rebuilding a utility tractor for daily chores or restoring a larger machine for heavy field work, these bearings handle the constant loads and vibration that come with farming operations.

Made to Last

Engine bearings are the heart of any rebuild, and these are built to handle the punishment. Quality bearing material and precise manufacturing ensure proper oil film thickness and heat transfer, while the oversize design compensates for crankshaft machining to restore factory clearances.

Good to Know

This is a job for a qualified machine shop or experienced mechanic with proper measuring tools. Make sure your crankshaft has been ground to the correct .254 oversize specification before installation. Always check all clearances with plastigauge and torque main caps to specification—sloppy assembly here means starting over.
