Frequently Asked Questions

What brake parts fit a Case 340B articulated dump truck?

Case 340B trucks use ZF axle brake hardware including brake snap rings, brake pins, adjuster cup springs, and axle sealing rings. These same components cover the 335 and 340 models. Match the part number to your axle to confirm the correct piece.

Are Case dump truck brake parts the same as loader brake parts?

Many of these components are common ZF axle service parts shared across several Case machines, which is why the fitment often spans multiple models. Always verify by the part number listed on each item rather than by machine alone.

How do I know which brake snap ring I need for a Case 340B?

Identify the ZF axle on your truck and match it to the part number for the snap ring or retainer ring you need, since several ring sizes are used. If you are unsure, call our parts team at (800) 909-7060 to confirm the right fit.

Do you carry axle sealing O-rings for Case articulated dump trucks?

Yes, Broken Tractor offers axle housing and cover O-rings and small housing O-rings used in the ZF axle and brake assemblies on 325 through 340B trucks. Confirm the seal dimensions against your axle before ordering.
