If you’ve noticed hydraulic oil pooling under your tractor or your three-point hitch feeling sluggish, the pump shaft seal is likely the culprit. This small but critical seal keeps your hydraulic fluid where it belongs while preventing dirt and debris from destroying your pump internals. When it starts leaking, you’re not just wasting expensive hydraulic fluid—you’re risking pump damage that’ll cost far more than this seal.
What You’re Getting
- Precision-sized rubber seal that matches OEM specifications for proper fit
- Heat and chemical-resistant construction handles modern hydraulic fluids
- Spring-loaded lip design maintains constant sealing pressure
- Direct replacement for pump QTP-2488 used across multiple John Deere series
Built for Real Farm Work
This seal works in the hydraulic pumps found on a wide range of John Deere tractors from compact utility models up through mid-size row crop machines. Whether you’re running a loader, operating your three-point hitch, or powering remote hydraulics, this pump keeps everything working smoothly. These tractors handle everything from hay production and livestock chores to row crop farming and heavy tillage work.
Made to Last
Farm equipment seals take a beating from temperature swings, pressure spikes, and contamination. This seal uses modern rubber compounds that resist the heat and chemicals that destroyed the original seal. The metal case won’t corrode, and the spring-loaded lip maintains proper contact even as the shaft develops minor wear over time.
Installation Notes
Most mechanics can swap this seal without pulling the pump completely off the tractor. Clean the seal bore thoroughly—any debris will destroy the new seal quickly. A thin coat of hydraulic fluid on the seal lips helps installation and prevents dry-running damage during startup. If the old seal has been leaking for a while, check your fluid level and change the filter while you’re at it.
