Crankshaft Thrust Bearing for John Deere Tractors with 4239T, 4039T, 6359T Engines

Description

If you’ve been hearing that telltale knocking or experiencing mysterious engine vibration, there’s a good chance your crankshaft thrust bearing has seen better days. When this small but critical component wears out, it lets your crankshaft move fore and aft where it shouldn’t—setting you up for expensive engine damage and costly downtime right when you need your tractor most.

What You’re Getting

• Precision-sized at 20 thousandths clearance for proper crankshaft positioning
• Engineered for high-stress diesel engine applications that work hard all day
• Direct replacement bearing that restores factory-spec crankshaft end play
• Quality construction that handles the heavy loads these older tractors were built for

Built for Real Farm Work

This thrust bearing fits the workhorses of many farm operations—those reliable John Deere tractors powered by 4239T, 4039T, 6359T, 4239D, 6359D, 4045T, and 6068T engines. From the smaller utility tractors that handle daily chores to the bigger machines pulling heavy implements through tough ground, these engines were designed to run hard season after season.

Made to Last

Engine thrust bearings take tremendous abuse from the constant push and pull forces created by your tractor’s transmission and PTO loads. This bearing is built with materials that can handle the heat, pressure, and contamination that comes with agricultural engine work. It’s the same quality you’d expect from the original equipment.

Good to Know

Thrust bearing replacement requires engine teardown, so it’s typically done during major engine rebuilds or overhauls. If you’re already pulling your engine apart, now’s the time to replace this bearing along with your main bearings and rod bearings. The 20-thousandths specification is critical—too loose and you’ll get knock, too tight and you’ll get binding.
