Description
When your old John Deere two-cylinder starts knocking or showing signs of low oil pressure, worn connecting rod bearings are usually the culprit. These bearings sit right between your connecting rods and crankshaft, taking the brunt of every combustion stroke while keeping everything moving smoothly. A fresh set gets your vintage tractor’s heart beating strong again and protects that crankshaft from expensive damage.
What You’re Getting
- Complete pair of standard-size rod bearings for both cylinders in your engine
- Precision-manufactured bearing material that maintains proper oil clearances
- Built to handle the unique loads and RPM characteristics of two-cylinder engines
- Quality construction that resists fatigue even under heavy pulling loads
Built for Real Farm Work
These bearings are engineered specifically for the 100 and 113 cubic inch two-cylinder gas engines found in John Deere 40, 320, and 330 tractors. Whether you’re using your vintage Deere for light farm work, mowing, or just keeping a piece of history running, these machines were built to work and these bearings keep that tradition alive.
Made to Last
Two-cylinder engines put different stresses on bearings than modern multi-cylinder designs, with longer power strokes and different vibration patterns. These bearings are manufactured with bearing materials that handle those unique characteristics while maintaining the tight tolerances needed for proper lubrication and long life.
Good to Know
Installing connecting rod bearings requires complete engine disassembly and is definitely a job for someone with engine rebuilding experience. It’s the perfect time to check your crankshaft journals for wear, inspect the rods themselves, and consider refreshing other engine internals. Always check bearing clearances with plastigauge before final assembly to make sure everything’s within factory specifications.
