Description
When your tractor’s engine starts knocking or making that telltale rod bearing noise, it’s time to get serious about an engine rebuild. This standard-size connecting rod bearing set is what you need to restore proper clearances and quiet operation in your Case diesel engine. Four bearings handle the job in both the naturally aspirated A267D and turbocharged A336BD engines, giving your pistons the smooth, reliable support they need to keep pulling through another season.
What You’re Getting
- Complete set of four standard-size connecting rod bearings for one engine
- Precision-manufactured to OEM specifications for proper oil clearance
- Durable construction designed to handle the stress of diesel engine operation
- Direct replacement for worn bearings—no machine work needed on standard wear
Built for Real Farm Work
These bearings are designed for the A267D four-cylinder diesel and A336BD turbocharged four-cylinder diesel engines found in various Case tractor models. Whether you’re running a utility tractor for loader work or a row-crop machine through heavy soil conditions, these engines were built to work hard. The turbocharged A336BD engines (serial number 2539000 and up) demand even more from their bearings due to increased power output.
Made to Last
Connecting rod bearings take tremendous punishment in diesel engines, supporting the pistons through thousands of combustion cycles while maintaining critical oil film thickness. TISCO builds these bearings with the proper materials and tolerances to handle the high pressures and temperatures of diesel operation. They’re manufactured to the same standards as original equipment, so you get the reliability you need for long service life.
Good to Know
This is a standard-size bearing set, which means your crankshaft journals should measure within factory specifications. If your crank has been ground undersize, you’ll need the appropriate undersize bearings instead. During installation, always check your connecting rod bolt condition and torque specifications—stretched or damaged bolts can cause bearing failure even with new parts.
