All Balls 25-4044 Countershaft Seal Kit 2014-2025 Yamaha YZ250F WR250F

A leaking countershaft seal is more than just a mess on your garage floor; it’s a threat to your engine’s oil pressure and overall health. The All Balls Countershaft Seal Kit is a Heavy Duty solution designed to replace worn factory components and stop leaks at the source. At Moto-House MX, we understand that reliability is everything when you're hitting the trails or the track, which is why we provide high-performance seals that stand up to the elements.

Built for Racing Performance, this kit features an upgraded seal design and a hardened steel bushing to prevent the "grooving" common with standard parts. Whether you are performing a routine OEM Replacement or prepping for a race season, this Made in the USA kit provides a precise fit for your Yamaha 250F. Each kit comes complete with the necessary O-ring and snap ring or lock washer where applicable, ensuring your drivetrain remains sealed and secure.

Frequently Asked Questions

Q: Why does the kit include a new bushing instead of just the seal?
A: The bushing is a wear item; dirt and grit often score the metal, creating a path for oil to leak even with a brand-new seal. Replacing both ensures a proper, long-lasting fix.

Q: Is this kit compatible with the 2025 Yamaha YZ250F?
A: Yes, this kit is specifically designed to fit the Yamaha YZ250F models from 2014 through the current 2025 model year.

Q: Does the seal require any special lubricants for installation?
A: We recommend a light coating of clean engine oil or assembly lube on the inner lip of the seal and the O-ring to prevent "dry start" wear during the first few rotations.
