Description

If you’ve worked on Ford 40 series or TS tractors with dual power transmissions, you know how important the little sealing parts can be. This O-ring might look simple, but it’s one of those critical pieces that keeps hydraulic fluid where it belongs and prevents contamination from getting into your dual power system. When these start to leak, you’ll notice it quickly—and so will your hydraulic fluid bill.

What You’re Getting

Precise fit designed specifically for Ford 40 series and TS dual power systems
High-quality rubber compound that handles hydraulic pressure and temperature swings
Direct replacement that seals properly without modifications or adapters
Sold in convenient 5-pack—handy since these tractors use multiple rings

Built for Dual Power Work

This O-ring is engineered for the Ford 40 series tractors (like your 5640, 6640, 7740, 7840, 8240, and 8340) and TS series models (TS80, TS90, TS100, TS110, TS115) equipped with dual power transmissions. These are serious work tractors that handle everything from field cultivation to heavy loader work, and their dual power systems need reliable sealing to shift smoothly under load.

Made to Last

Farm hydraulics put O-rings through the wringer with pressure spikes, temperature changes, and constant cycling. This ring is built with materials that resist the breakdown that kills cheaper seals, keeping your dual power system sealed and shifting properly season after season.

Installation Notes

Clean the O-ring groove thoroughly before installation—any dirt or debris will cause premature failure. A light coating of clean hydraulic fluid helps the ring slide into place without nicking or twisting. Keep spares on hand since dual power repairs often reveal other seals that need attention while you’ve got everything apart.
