Description

Nothing ruins your day quite like the low rumble that means your engine’s main bearings are calling it quits. When you start hearing that telltale knock from deep inside the motor, it’s time to act fast before a bearing failure turns a manageable repair into a complete engine rebuild. This main bearing kit gives you everything needed to restore that smooth, quiet operation and keep your tractor running strong for years to come.

What You’re Getting

Standard size bearings designed for engines that haven’t been machined oversize
Complete set replaces all main bearings in one service
Quality construction that meets OEM specifications for proper fit and durability
Precision-manufactured bearing shells that maintain proper oil clearances

Built for Real Farm Work

These bearings are engineered to handle the constant demands of agricultural work – from the steady loads of PTO operation to the high-stress moments when you’re pulling through tough ground. Farm engines work harder and longer than most, and this bearing kit is built to match that endurance with materials and construction that stand up to heat, pressure, and the vibration that comes with real work.

Made to Last

Main bearings are the foundation of your engine’s reliability. These replacement bearings use quality materials and precise manufacturing to ensure they’ll support your crankshaft properly while maintaining the oil film that prevents metal-to-metal contact. The standard size is for engines that are still within factory specifications and haven’t been machined for oversized bearings.

Good to Know

This is a job for someone with engine rebuild experience – main bearing replacement requires removing the oil pan and often the crankshaft. Check your crankshaft journals with a micrometer to confirm they’re still standard size before ordering. If you’re this deep into the engine, it’s smart to replace the rod bearings and check other wear items while you’re at it.
