Description
Nothing kills a productive day like transmission fluid puddling under your tractor or noticing that telltale drip when you park for lunch. Powershift transmissions rely on precise electrical signals to manage gear changes, but they also depend on proper hydraulic sealing to maintain pressure and keep everything lubricated. This input shaft O-ring is one of those small parts that makes a big difference when it’s doing its job right.
What You’re Getting
- Precision-molded O-ring designed specifically for TM series transmission input shaft applications
- Oil-resistant rubber compound that stands up to transmission fluid and temperature changes
- Exact fit that seals properly without binding or rolling during installation
- Quality construction that maintains its seal even with the constant rotation and pressure of transmission operation
Built for Real Farm Work
This O-ring fits Ford New Holland TM series tractors (TM115 through TM190) and TM Brasil series models. These powerful tractors are workhorses on large farms handling everything from heavy tillage and planting to harvest operations. Whether you’re running a TM130 for row crop work or pushing a TM175 through heavy soil preparation, the transmission input shaft takes a beating and needs reliable sealing.
Made to Last
Transmission O-rings live in a tough environment—constant exposure to hot hydraulic fluid, pressure changes, and vibration from field work. This O-ring is made from materials specifically chosen to handle transmission fluid without swelling, cracking, or losing flexibility. It maintains its sealing properties through thousands of operating hours and temperature cycles.
Installation Notes
This is a straightforward replacement that requires accessing the transmission input shaft area. Clean the shaft groove thoroughly before installation and inspect the surface for any nicks or scratches that could cause future leaks. A light coating of clean transmission fluid helps the O-ring slide into place without damage. Take your time during reassembly—rushing leads to pinched seals and repeat repairs.
