Built for Real Farm Work

These bearings fit a wide range of John Deere engines from compact 201 CID gas units up through heavy-duty 466 CID diesel powerplants. Whether you’re rebuilding the engine in a utility tractor that runs the hay equipment or overhauling a big row-crop machine that pulls through tough soil conditions, these bearings handle the job.

Made to Last

Engine bearings take tremendous abuse from combustion forces, heat cycles, and constant rotation. These are engineered with proper oil clearances and durable materials that maintain their integrity through thousands of hours of operation. The precise manufacturing ensures they’ll mate properly with your machined crankshaft for long-term reliability.

Good to Know

Rod bearing replacement requires proper torque specifications and clean assembly practices. Always check your crankshaft journal dimensions before ordering – these 0.030 undersize bearings are specifically for cranks that have been turned 0.030 under. Keep everything spotless during assembly, and don’t forget to prime the oil system before first startup.
