Description
When your transmission starts seeping oil around the input housing, it’s not just messy—it’s a sign that seals are wearing out and contamination could get in. This input housing O ring provides the tight seal your transmission needs to keep oil where it belongs and dirt where it doesn’t. A simple part that makes a big difference in keeping your tractor running smooth.
What You’re Getting
- Precision-sized nitrile rubber construction that handles the heat and pressure of hard work
- 132.94mm outer diameter with 3.53mm cross-section for a perfect factory fit
- 70 Shore durometer rating means it stays flexible yet tough through temperature swings
- Direct OEM replacement that installs just like the original
Built for Real Farm Work
This O ring fits the transmission input housing on Case IH tractors from the smaller 84 series utility models up through the 95 series workhorses. Whether you’re running a 485 around the farmyard or pulling heavy implements with an 895, this seal keeps transmission oil from leaking out and contaminants from getting in.
Made to Last
Nitrile rubber construction is specifically chosen for transmission applications because it resists petroleum products and holds up to the constant heat cycling that comes with field work. The 70 Shore hardness rating gives you the right balance of flexibility for sealing and durability for long service life.
Installation Notes
Clean the housing groove thoroughly before installing the new O ring—any dirt or old seal material will cause leaks. A thin coat of transmission fluid on the new seal makes installation easier and helps prevent damage during assembly.
