Description
If your three-point hitch won’t stay up or your implements are slowly drifting down while you work, worn seals in your hydraulic lift cylinders are likely the culprit. That sinking three-point hitch or slow lift response usually points to worn seals in your hydraulic lift cylinders. When your implements won’t stay up or lifting becomes sluggish, this complete seal kit provides the fix without expensive cylinder replacement. This 85mm seal kit brings back the solid lifting power your John Deere had when it rolled off the factory floor.
What You’re Getting
- Complete seal set designed specifically for 85mm bore hydraulic lift cylinders
- High-quality seals that resist modern hydraulic fluids and temperature extremes
- Precise tolerances that restore proper sealing without excessive wear
- All the components needed for a complete cylinder rebuild
Built for Real Farm Work
Your John Deere tractor’s hydraulic lift system works constantly throughout the day. Whether you’re operating a loader with a 6410, raising and lowering tillage equipment with a 6520, managing hay tools with a 6330, or working with precision implements on a 6125M, reliable hydraulics are essential. Worn cylinder seals cause implements to drift down, reduce lifting capacity, and create messy external leaks that waste expensive hydraulic fluid.
Made to Last
These aren’t generic O-rings that sort-of fit – they’re precision seals designed specifically for your hydraulic pump’s operating pressures and temperatures. Modern hydraulic fluids can be tough on older seal materials, but this kit uses updated compounds that resist breakdown while maintaining flexibility. When you rebuild with quality seals, you’re getting the same reliability John Deere engineered into your tractor.
Installation Notes
Cylinder rebuilding requires cleanliness above all else – any contamination causes rapid seal failure. Install seals using proper tools to avoid damage – never use sharp objects. Lubricate with clean hydraulic fluid during assembly. After rebuilding, cycle slowly at first to seat seals properly. Change hydraulic fluid and filters after rebuilding to remove any contamination.
