Description
When you hear that telltale knocking from deep in your diesel engine or notice oil pressure dropping, it’s usually the main bearings crying for help. After thousands of hours of hard work, even the toughest engines need their bearings replaced. This main bearing kit gives you everything needed to rebuild those worn journals back to proper clearances, getting your CDC-B series engine running smooth and reliable again.
What You’re Getting
- Complete set of main bearings sized 1mm undersized for professionally machined crankshafts
- Precision-manufactured bearings that meet or exceed OEM specifications for durability
- Proper clearances designed for the demands of agricultural diesel engines
- Quality construction that handles the loads these 3.9L powerplants put out
Built for Real Farm Work
This kit is engineered specifically for CDC-B series non-emission 4-cylinder 3.9L diesel engines that power various agricultural equipment. These engines are workhorses in tractors and implements that handle everything from tillage to harvest operations, where reliability isn’t just important—it’s essential to getting the job done.
Made to Last
Farm engines work harder than most, dealing with dust, vibration, temperature swings, and long hours under load. These bearings are built to handle those conditions, using materials and manufacturing processes designed for the agricultural environment where failure means expensive downtime during critical seasons.
Good to Know
This is an undersized bearing kit, which means your crankshaft will need to be professionally machined to the proper dimensions before installation. Have your crank checked by a machine shop for straightness and journal condition. Remember to check connecting rod bearings while you’re in there—they often wear at similar rates and it’s cheaper to do them all at once than tear everything apart again later.
