Description

When your tractor starts knocking or you hear that tell-tale rumbling from the bottom end, it’s time to deal with worn main bearings before they destroy your crankshaft. This .010 oversize main bearing kit gives you the precision-sized bearings needed to restore proper crankshaft support after a machine shop has turned your crank journals to .010 under. It’s the difference between a successful engine rebuild and having to hunt down a replacement block.

What You’re Getting

Complete set of main bearings sized .010 oversize for properly machined crankshafts
Quality TISCO construction designed to handle the loads and stress of agricultural engines
Precision tolerances that restore proper oil clearance and pressure
Direct replacement for worn factory bearings when used with machined crank journals

Built for Real Farm Work

These main bearings are engineered for the demanding conditions of agricultural engines that run long hours under heavy loads. Whether your engine powers through days of plowing, runs a PTO-driven baler non-stop during hay season, or pulls heavy implements through tough ground, these bearings provide the foundation that keeps your crankshaft properly supported and your engine running smooth.

Made to Last

TISCO builds these bearings with the material quality and manufacturing precision needed for reliable service in farm tractors. The bearing material is formulated to handle the shock loads and varying RPMs that come with agricultural work, while proper surface treatments ensure compatibility with modern oils and long service life under demanding conditions.

Good to Know

This is a machine shop job that requires turning your crankshaft journals to .010 under standard size before installing these oversized bearings. Always have your crank checked for straightness and surface finish before assembly. Proper engine assembly procedures are critical – follow torque specifications and use quality assembly lube during installation. It’s also the perfect time to replace rod bearings, oil pump, and other wear items while you have the engine apart.
