Description
When you notice hydraulic fluid dripping near your transmission or your shifting just doesn’t feel as smooth as it used to, this little O-ring might be the culprit. It’s one of those parts that doesn’t look like much, but when it fails, you’ll know it – internal bypassing means fluid takes the easy path instead of building proper pressure where you need it. External leaks follow soon after, creating fire hazards near hot engine parts and making a mess of your shop floor.
What You’re Getting
- Precision-molded O-ring that seals the transmission input shaft properly
- Compound specifically formulated to resist the EP (extreme pressure) additives in modern gear oils that destroy cheaper seals
- Exact fit replacement that restores factory sealing specs
- Quality material that handles the heat cycles and pressure spikes of transmission operation
Built for Real Farm Work
This O-ring fits a wide range of New Holland tractors from the reliable TM series workhorses through the modern T6 and T7 series, plus Case IH MXM and Puma models. Whether you’re running a TM150 on heavy tillage, pulling a planter with a T6.180, or handling loader work with a Puma 165, your transmission depends on proper sealing to maintain hydraulic pressure for smooth shifting under load.
Made to Last
Modern seal materials resist the heat and pressure that destroyed original seals, giving you better reliability than when new. This O-ring provides the proper barrier that maintains system pressure while keeping contaminants out of your hydraulic fluid.
Good to Know
While you’re in there replacing this O-ring, it’s smart to check the condition of other seals in the area – they’ve all endured the same heat cycles and contamination, so fix one and another often fails within weeks. Use assembly lube during installation and consider changing your hydraulic filter and fluid when done – clean fluid extends seal life dramatically.
