Description
When your diesel engine starts knocking or showing signs of excessive wear, worn rod bearings are often the culprit. Whether you’re rebuilding after years of hard work or addressing damage from oil starvation or contamination, this undersized rod bearing kit gets your engine back to proper tolerances and smooth operation.
What You’re Getting
- Complete set of rod bearings sized 0.75mm under standard for proper crankshaft clearances
- Precision-manufactured bearings that handle the constant loads and temperature cycling of diesel operation
- High-quality materials designed to work with proper lubrication for thousands of hours
- One complete kit services all cylinders in your 4-cylinder CDC-B series engine
Built for Real Farm Work
This kit is specifically designed for CDC-B series non-emission 4-cylinder 3.9L diesel engines found in agricultural tractors and equipment. These reliable workhorses power everything from utility tractors to compact loaders, handling the demanding conditions of daily farm operations where reliability matters most.
Made to Last
Rod bearings take a beating in any diesel engine, especially under the loads and long hours common in farm work. These bearings are manufactured to handle the reciprocating forces and heat that come with diesel combustion, providing the smooth operation and durability you need between overhauls.
Installation Notes
This is a complete engine rebuild job requiring disassembly down to the crankshaft. The undersized bearings are designed for crankshafts that have been machined to restore proper journal surfaces. Make sure your crankshaft has been ground exactly 0.75mm under standard diameter before installation.
