Frequently Asked Questions

How do I find the right transmission part for my Case IH tractor?

Start with the part number stamped on or listed for your original component, along with your tractor model and serial number. Transmission parts can change within the same model, so the serial number matters. If you are unsure, call (800) 909-7060 and our parts team can help confirm the match.

Do Farmall and International tractors share rear axle parts?

Some rear axle parts are shared across related models, but many are not. Fitment often depends on the specific series and serial number range, so parts that look alike may not interchange. Matching the part number is the safest way to confirm.

What are signs of a worn rear axle bearing or seal on a Farmall tractor?

Oil leaking around the axle housing or onto the wheel is a common sign of a failing seal. Grinding, rumbling or excess play at the wheel can point to a worn bearing. Catching these early helps protect the rest of the rear axle.

Should I repair or replace a worn Case IH transmission component?

If a gear, shaft or bearing shows chipped teeth, pitting or heavy wear, replacing it is usually the better choice. Reusing worn parts can lead to repeat teardowns and damage to mating components.
