Frequently Asked Questions

What flywheel fits a John Deere 4020?

We carry flywheels and ring gears listed for the 4020 along with the 3010, 3020, 4010, and related row-crop models. Fitment varies by build and serial number, so match the part number on your original flywheel or confirm with the parts team before ordering.

Can I replace just the ring gear instead of the whole flywheel?

Yes. When the flywheel body is sound but the starter teeth are worn or chipped, a replacement ring gear restores proper starter engagement. We offer standalone ring gears such as T20088, R26054, and AR103044.

What is the flywheel dowel pin for on a John Deere 3020?

The dowel pin locates and aligns the flywheel to the crankshaft during assembly so the bolt pattern lines up correctly. We carry dowel pins like R40731 for the 500 series and 3010, 3020, 4000, 4010, and 4020 tractors.

Do you have flywheels for tractors with independent PTO?

Yes. AR92508 is a flywheel for independent PTO applications fitting 1830 through 3130 tractors. If you are unsure which flywheel your machine uses, call (800) 909-7060 and the parts team can help match it.
