Frequently Asked Questions

Does the flywheel ring gear fit Case 584E, 585E, and 586E forklifts?

Yes, the Flywheel Ring Gear (SKU J901774) fits Case 584E, 585E, and 586E rough terrain forklifts. Fitment can vary by serial number, so match the part number to your machine or confirm with our parts team before ordering.

What causes a no-crank or hard-start problem on a Case forklift?

Worn, chipped, or missing teeth on the flywheel ring gear are a common cause of hard-start and no-crank issues, since the ring gear engages the starter pinion to turn the engine. Inspect the ring gear teeth for damage when troubleshooting cranking problems. If the teeth are worn, the ring gear (SKU J901774) is the part that engages the starter drive.

What does the flywheel ring gear do on a Case forklift?

The ring gear provides the toothed surface that the starter pinion engages to crank the engine and transfer crankshaft rotation. On Case 584E, 585E, and 586E forklifts it gives a balanced mounting face for the engine assembly. A damaged or worn ring gear can prevent reliable engine cranking.

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

We carry flywheel ring gears such as SKU J901774 that engage the starter pinion. Whether you replace the ring gear or the full flywheel depends on the condition of both, so inspect the flywheel mounting face and teeth. Contact our parts specialists at (800) 909-7060 if you need help identifying the right part for your machine.

Are new and used Case forklift flywheels available?

Broken Tractor offers both new and used flywheel and ring gear options for Case 584E, 585E, and 586E forklifts. Fitment is verified before every order and parts ship fast from two US locations.
