Rod Bearing Kit 0.25mm Undersized for 4 Cylinder 3.9L Diesel Engines

Description

When you start hearing knocking sounds from your engine or notice a drop in power, worn connecting rod bearings are often the culprit. Connecting rod bearings take some of the hardest punishment in your engine, especially during heavy pulling or PTO work. This undersized bearing kit is designed for engine rebuilds where the crankshaft journals have been machined 0.25mm smaller to restore proper surfaces and clearances.

What You’re Getting

• Complete set of connecting rod bearings sized 0.25mm undersized for machined cranks
• Built with bearing materials that resist fatigue and maintain proper oil clearances even under the temperature swings and contamination that agricultural engines face. The precision manufacturing ensures they’ll seat properly and provide consistent performance.
• Quality construction designed to handle the constant loads and vibration of diesel engine operation
• Direct fit for CDC-B Series non-emission 4 cylinder 3.9L diesel engines

Built for Real Farm Work

This bearing kit is engineered specifically for CDC-B Series 4 cylinder diesel engines found in agricultural tractors and equipment. Whether you’re running PTO equipment, pulling heavy implements, or handling loader work, these bearings are built to handle the demanding conditions that come with real farm use.

Made to Last

These are built with bearing materials that resist fatigue and maintain proper oil clearances even under the temperature swings and contamination that agricultural engines face. The undersized design allows for proper rebuild procedures when crankshaft journals need to be machined to remove scoring or wear.

Installation Notes

Installing connecting rod bearings requires complete engine disassembly and is definitely a job for someone with engine rebuilding experience. This is typically part of a complete engine overhaul along with other wear components. Make sure your crankshaft has been properly machined to 0.25mm undersize before installation for proper clearances and performance.
