Description

If you’ve noticed that rough shake at certain RPMs or heard an odd rumble coming from under the hood, your crankshaft pulley might be telling you it’s time for a replacement. This torsional damper sits on your crankshaft and smooths out the natural twist and vibration that happens when pistons fire, keeping your engine running smooth and protecting expensive components from damage.

What You’re Getting

Heavy-duty construction that dampens crankshaft vibrations and prevents damage to bearings and seals
Direct OEM replacement that fits exactly like the factory part—no modifications needed
Balanced design that eliminates engine shake and rough idle at operating RPMs
Durable rubber and steel construction built to handle the punishment of farm work

Built for Real Farm Work

This damper is designed for the demanding John Deere 20, 30, 40, and 55 series tractors that power through everything from heavy tillage to long transport days. Whether you’re running a 4230 through tough clay or pushing a 4440 through marathon planting sessions, this component keeps your engine’s power delivery smooth and reliable when you need it most.

Made to Last

Farm engines work harder and longer than most, and this damper is built to handle that punishment. The rubber dampening element is designed to resist cracking from temperature changes and vibration, while the steel hub holds up to the constant stress of engine operation.

Good to Know

Installation requires removing the cooling fan and pulley assembly to access the crankshaft—it’s a job best done with proper pulley pullers and a helper. Don’t wait too long if you’re feeling vibration, as a failed damper can cause expensive damage to your engine’s internal components.
