Hot Rods OSK0052 Transmission Countershaft Seal Kit Suzuki DR-Z400 2000-2013

Fast and Reliable Countershaft Leak Repair

A leaking countershaft seal is more than just an oily mess on your garage floor; it can lead to low oil levels and catastrophic engine damage if left unchecked. The Hot Rods Transmission Countershaft Seal Kit, available at Moto-House MX, provides a professional-grade, all-in-one solution to stop leaks at the source. Engineered for a precision fit, this kit allows you to restore the integrity of your transmission's output shaft without the need to hunt down individual parts.

Every OSK0052 kit is built for durability and long-term performance in both off-road and street environments. This complete repair set includes the high-quality Hot Rods countershaft seal, the essential countershaft bushing, necessary O-rings, and the sprocket nut washer where applicable. By replacing the bushing and O-rings alongside the seal, you ensure a perfect mating surface that prevents premature wear and future leaks, keeping your 400cc powerplant running clean and protected.

Expert Pro-Tip

Always inspect the countershaft itself for any burrs or sharp edges before sliding the new seal and bushing on; a small piece of electrical tape over the shaft splines during installation can prevent the new seal lip from being torn.

Frequently Asked Questions

Q: Do I need to split the engine cases to install this kit?
A: No, the countershaft seal and bushing can be replaced from the outside of the engine after removing the front sprocket and spacer.

Q: Why should I replace the bushing if only the seal is leaking?
A: Over time, the seal wears a groove into the bushing. If you only replace the rubber seal, it may not sit perfectly in that old groove, leading to a leak shortly after installation.

Q: Does this kit include the sprocket nut?
A: This kit includes the sprocket nut washer (locking washer), but does not include the actual threaded sprocket nut.

Recommended Pairings: Front Sprockets & High-Performance Chain Lube.
