Description
When you start hearing that telltale knock from down in the engine block, it’s time to address those worn main bearings before a small problem becomes a big one. Main bearings are what keep your crankshaft spinning smoothly, and when they’re worn, you’ll know it. This complete main bearing kit gets your CDC-B series engine back to running quiet and strong.
What You’re Getting
- Complete set of undersized bearings (0.25mm under) for rebuilding worn engine blocks
- TISCO quality construction that meets the demands of agricultural work
- Precision tolerances that restore proper oil clearances and pressure
- Everything you need in one kit—no hunting around for individual pieces
Built for Real Farm Work
This kit is specifically designed for CDC-B series non-emission 4-cylinder 3.9-liter diesel engines found in various tractors and agricultural equipment. These are the workhorses that power through long days of plowing, cultivating, and harvesting, so the bearings need to handle serious loads and extended run times.
Made to Last
TISCO builds these bearings to handle the oil contamination, temperature swings, and constant vibration that come with farm equipment. The undersized design compensates for crankshaft wear, giving you a proper fit and reliable lubrication when your crank journals have seen better days.
Installation Notes
This is an undersized bearing kit, so make sure your crankshaft has been properly machined before installation. Check your clearances carefully during assembly—proper bearing clearance is critical for oil pressure and engine longevity. Take your time with the torque specs, and don’t forget to prime the oil system before first startup.
