When you’re rebuilding that vintage TEF20 engine and the crankshaft journals need some machine work, you’ll need these 20 thousandths oversized big end bearings. 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. If your TEF20 is knocking or losing oil pressure, worn connecting rod bearings are often the culprit.
What You’re Getting
- Oversized bearings machined to 20 thousandths over standard size for rebuilt cranks
- Proper bearing material designed for the loads and speeds of agricultural engines
- Quality construction that handles the stop-and-go operation typical of farm work
- Direct replacement for worn factory bearings when your crank has been turned
Built for Engine Rebuilding
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. When rebuilding these classic engines, oversized bearings let you restore proper clearances after the crank journals have been machined to remove wear and scoring.
Made to Last
Engine rebuilding isn’t cheap, so you want bearings that’ll go the distance. These are built with the right bearing material and oil grooves to handle the lubrication requirements of that four-cylinder Continental engine. They’re designed to work with the oil pressures and clearances these older engines were built around.
Good to Know
These are 20 thou oversized, which means your machine shop turned the crank journals 0.020″ under standard size. Make sure your machinist checks the journal finish and measures everything twice – bearing clearance is critical for oil pressure and engine life. Most shops will also check the connecting rods for straightness while they’re at it.
