Description
When your TEF20 starts knocking or you notice metal shavings in the oil, it’s time to take a closer look at those connecting rod 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. These big end bearings are what keep your connecting rods from wearing out the crankshaft—pretty important stuff for keeping your classic tractor running strong.
What You’re Getting
- Standard size bearings with 85mm outer diameter and 80mm inner diameter for proper crankshaft clearance
- Precision-manufactured to original specifications for reliable fit and performance
- Quality materials designed to handle the loads and heat of continuous engine operation
- Direct replacement that restores proper oil clearances and reduces engine noise
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. Whether your TEF20 is still earning its keep or has been restored for shows, proper bearing clearances are essential for long engine life.
Made to Last
These bearings are built to handle the unique demands of vintage tractor engines that often run at consistent RPMs for hours at a time. The material composition provides the right balance of strength and conformability to work with older crankshafts that might not be perfectly round anymore. Proper oil film thickness is maintained even under the varying loads that come with different implements and field conditions.
Good to Know
Installing connecting rod bearings requires pulling the oil pan and removing the rod caps, so it’s a good time to check your main bearings too. Always use a torque wrench when reassembling—proper rod bolt tension is critical for bearing life. Take measurements of the old bearings and check crankshaft journals for wear before installation. If you’re not comfortable with internal engine work, this job is best left to someone with experience rebuilding vintage tractor engines.
