Description
When your diesel engine starts knocking or you find metal flakes in the oil, worn rod bearings are often the culprit. This 1mm undersize bearing kit is what you need when the crankshaft journals have been machined down during a rebuild. Getting the right bearing size is critical—too tight and you’ll seize the engine, too loose and you’ll be right back where you started with bearing knock.
What You’re Getting
- Complete bearing set for all connecting rods in your 4-cylinder engine
- Precision-manufactured 1mm undersize bearings for machined crankshafts
- High-quality materials that handle the heat and stress of diesel operation
- Exact replacement specifications for CDC-B series engines
Built for Real Farm Work
These bearings are designed specifically for CDC-B series 3.9L 4-cylinder non-emission diesel engines found in various agricultural and industrial equipment. These reliable powerplants are workhorses in smaller tractors, generators, and specialty farm equipment where dependable operation is crucial for getting the job done.
Made to Last
Rod bearings take a beating from the constant pounding of combustion forces and high oil temperatures. These bearings are built with the right materials and tolerances to handle diesel engine demands. The undersize design compensates for crankshaft wear, giving you a proper oil clearance that keeps everything lubricated and running smooth.
Installation Notes
This is a job for an experienced engine rebuilder with proper measuring tools. You’ll need to verify your crankshaft journals are machined to the correct undersize before installation. Take your time with torque specs and bearing clearances—getting it right the first time saves a lot of headaches down the road.
