Description

When you start hearing that telltale knocking sound from under the hood or notice oil pressure dropping, your engine’s main bearings are likely crying for help. These bearings support the crankshaft and keep your engine running smooth—when they’re worn, everything goes downhill fast. This complete main bearing kit gives you everything needed to rebuild your engine’s bottom end and get back to reliable operation.

What You’re Getting

Complete standard size bearing set for proper crankshaft support and oil clearance
Precision-manufactured bearings built to handle the constant loads of agricultural work
Quality TISCO construction that meets or exceeds original equipment specifications
All main bearings included for a complete bottom end rebuild

Built for Real Farm Work

This bearing kit is designed for tractors and equipment that work hard season after season. Whether you’re running a combine through harvest, pulling heavy implements during planting, or powering a hay baler in the heat of summer, your engine’s main bearings take tremendous abuse from constant vibration, load changes, and high operating temperatures.

Made to Last

Farm engines see conditions that would destroy automotive bearings in short order. This kit uses quality materials and manufacturing processes that handle contamination, temperature swings, and the extended operating hours that come with agricultural use. The precision tolerances ensure proper oil flow and clearances for long service life.

Installation Notes

Main bearing replacement requires complete engine teardown and proper measuring tools to check crankshaft condition. Have your crank inspected and ground if needed before installing new bearings. Torque specifications and assembly procedures are critical—this isn’t a job for shortcuts. Consider replacing connecting rod bearings at the same time since everything’s already apart.
