Description
When you hear that telltale knock coming from down in the bottom end of your engine, you know it’s time for a rebuild. Maybe the oil pressure’s been dropping, or you’ve noticed metal shavings in the oil filter—those connecting rod bearings are what keep your crankshaft spinning smoothly, and when they’re worn out, your whole engine suffers. These .030 oversize rod bearings get your diesel running quiet and strong again.
What You’re Getting
- .030 inch oversize to compensate for crankshaft journal wear and provide proper oil clearance
- Precision-manufactured bearing shells that handle the heavy loads of diesel engines
- TISCO quality construction built to last through thousands of hours of operation
- Complete bearing set—no need to hunt down individual pieces during your rebuild
Built for Real Farm Work
These bearings fit a wide range of John Deere 3-cylinder diesel engines found in compact and utility tractors from the ’70s through the ’90s. Whether you’re rebuilding the engine in your old 850 that’s been faithfully mowing for decades, or bringing a 950 back to life for loader work around the farm, these bearings handle the steady loads and daily operation that farm tractors demand.
Made to Last
Diesel engines create tremendous pressures and forces that regular bearings just can’t handle. These rod bearings are engineered specifically for the demands of agricultural diesel operation, with materials and coatings that resist wear even when dealing with the dust, dirt, and occasional marginal oil changes that come with farm life.
Good to Know
The .030 oversize means your crankshaft journals will need to be machined to the proper dimension—this isn’t a job for the shade tree mechanic. Take your crank to a reputable machine shop and have them turn the journals to the correct specifications. While you’re at it, check the connecting rods for straightness and resize the big ends if needed. Proper assembly torque and quality engine oil are critical for bearing life.
