Description
When your vintage TEF20 starts knocking or rattling during startup, it’s often the connecting rod bearings telling you they’ve seen better days. The Ferguson TEF20, often called the “Little Grey Fergie,” revolutionized farming in the 1940s and 50s with Harry Ferguson’s three-point hitch system. These 20-horsepower workhorses handled everything from plowing small fields to powering sawmills and hay balers. Fresh big end bearings restore that smooth, quiet engine operation and protect your crankshaft from expensive damage.
Key Features
- Proper 10-thou clearance spec for TEF20 four-cylinder engines – critical for correct oil pressure and bearing life
- Quality construction designed to handle the loads of both field work and PTO operations
- Direct replacement that fits without machine work or modifications
- Precision-manufactured to handle the thermal cycling and vibration these engines experience
- Set includes both connecting rod bearings for complete bottom-end service
Built for Real Farm Work
Today, these vintage machines are still working hard on small farms, market gardens, and hobby farms. They’re perfect for cultivation, hay operations, mowing, and light loader work. Many are also used for custom work like brush hogging, snow plowing, and maintaining large properties. The TEF20’s simple design and reliable engine make it a favorite for operators who value mechanical simplicity and dependable performance.
Made to Last
These bearings use proper bearing materials that can handle the unique demands of vintage tractor engines. The 10-thou specification ensures proper oil clearance for good lubrication while maintaining the tight tolerances these classic engines need. Quality construction means they’ll provide years of reliable service when properly installed with fresh oil and a clean filter.
Installation Notes
Big end bearing replacement requires removing the oil pan and connecting rod caps – a job that’s best done with the engine out or at least pulled forward. Check your crankshaft journals for wear and have them turned if needed before installing new bearings. Use proper torque specs for the rod bolts, and don’t forget to prime the oil system before first startup. It’s also smart to replace the oil pump and filter while you’re this deep into the engine.
