Description

When you’re shifting through the gears and something doesn’t feel right – maybe there’s play where there shouldn’t be, or the transmission feels loose – that little thrust washer in the input housing might be the culprit. This small but critical part keeps everything aligned and properly spaced inside your range box, preventing costly damage to gears and shafts when you’re working hard in the field.

What You’re Getting

Precision-manufactured washer that maintains proper gear spacing and alignment
Durable construction built to handle the constant pressure and movement of transmission components
Direct replacement part that restores original equipment specifications
Quality materials designed to withstand the heat and stress inside your transmission

Built for Real Farm Work

This thrust washer fits the range box assembly in Massey Ferguson 300 series tractors (362, 365, 372, 375, 382, 390, 398, 399) along with 4200 series models (4215, 4220, 4225, 4235, 4240, 4245, 4255, 4260, 4265, 4270) and 4300 series tractors (4315, 4320, 4325, 4335, 4345, 4355, 4360, 4370). These are the workhorses that handle everything from cultivation and hay operations to loader work and field transport, where reliable shifting is crucial for getting the job done efficiently.

Made to Last

The range box sees some serious action with all the shifting and gear changes you make during a long day of work. This thrust washer is engineered to handle the axial loads and maintain its dimensions even under the constant pressure and temperature changes inside your transmission. It’s built to OEM specifications using materials that won’t compress or wear prematurely.

Installation Notes

This is an internal transmission part that requires splitting the tractor or removing the range box for replacement. It’s typically replaced during major transmission work or when you’re experiencing shifting problems. If you’re already into the transmission for other repairs, now’s the time to check and replace thrust washers that show wear or damage.
