This critical O-ring is often the simple fix that solves complex problems. Don’t let a cheap seal turn into expensive transmission damage – this replacement O-ring gets your Dynashift working like it should.

What You’re Getting

Specifically designed for Dynashift wet clutch assemblies
Quality seal material that holds up to transmission fluid and heat cycles
This inexpensive seal protects expensive components from damage

Built for Real Farm Work

Massey Ferguson’s Dynashift transmission revolutionized tractor operation with clutchless shifting, using a wet clutch bathed in transmission fluid for smooth operation and long life. Whether you’re operating a 6190 on heavy tillage, using a 3690 for loader work, or running a 5465 on hay equipment, proper clutch function is essential. This O-ring maintains the hydraulic integrity that makes Dynashift transmissions so smooth and reliable.

Made to Last

When O-rings fail, fluid bypasses where it should, leading to low pressure, clutch slippage, and eventual failure. This replacement uses proper seal material that resists the swelling and deterioration caused by hot transmission fluid while maintaining flexibility throughout its service life. It’s built to handle the pressure and temperature cycles that wet clutch systems demand.

Good to Know

Access to this O-ring typically requires splitting the tractor, so it’s smart to replace other seals while you’re in there. Clean the seal groove thoroughly before installation and use a light coat of clean transmission fluid on the O-ring during assembly. Never use petroleum-based lubricants that can damage the seal material.
