Description

There’s nothing quite like being ready to start a long day in the field only to discover hydraulic fluid pooling under your tractor. When your range box starts leaking, that little O-ring inside is what’s usually to blame. This simple rubber seal keeps transmission fluid where it belongs and ensures your range shifts stay smooth and positive throughout the season.

What You’re Getting

Precision-molded seal designed specifically for MF range box applications
Hydraulic fluid resistant material that won’t swell or deteriorate over time
Direct replacement that fits properly without modifications
Quality construction that handles the pressure and temperature of working transmissions

Built for Real Farm Work

This O-ring fits the range box assembly in your 4200 or 4300 series Massey Ferguson. Whether you’re running a 4225 on mixed farming duties, using a 4270 for heavy field work, or operating a 4365 with a loader, this seal keeps your transmission’s range selection system working like it should. The range box is what gives you all those different speed options for everything from precision seeding to road transport.

Made to Last

Range boxes see constant pressure changes as you shift between ranges, and this O-ring is built to handle that abuse. The special rubber compound resists the breakdown that transmission fluid can cause to cheaper seals, while staying flexible enough to maintain a tight seal through temperature swings and vibration.

Installation Notes

Range box work typically requires splitting the tractor, so this isn’t a quick roadside fix. Most folks tackle this during other major transmission service or when they’re already into the range box for gear problems. Keep the work area absolutely clean – any dirt that gets into the transmission will cause expensive damage down the road.
