Description
That puddle of hydraulic fluid under your Massey Ferguson isn’t just messy – it’s expensive hydraulic oil draining away and a sure sign your pump seals are calling it quits. When your three-point hitch starts dropping slowly or your loader feels sluggish, worn pump seals are usually the culprit. This complete seal kit stops those leaks at the source and restores the full hydraulic pressure you need for serious farm work.
What You’re Getting
- Complete seal set for proper hydraulic pump rebuild – no hunting for individual seals
- High-quality seals designed to handle modern hydraulic fluids and operating pressures
- Direct replacement seals that fit precisely in worn pump housings
- Everything needed to eliminate both internal bypassing and external leaks
Built for Real Farm Work
Your Massey Ferguson 390, 390T, or other 300 series tractor depends on hydraulic power for three-point hitch operation, loader control, and remote hydraulics. These workhorses handle everything from loader work and cultivation to running hydraulically-controlled implements during planting and harvest. When pump seals fail, you don’t just lose fluid – you lose the pressure needed to lift heavy implements and operate equipment efficiently.
Made to Last
These aren’t generic O-rings that sort-of fit – they’re precision seals manufactured specifically for your hydraulic pump’s demanding operating conditions. The updated seal compounds resist breakdown from modern hydraulic fluids while maintaining the flexibility needed for proper sealing in worn housings.
Good to Know
Plan on 3-4 hours for a complete pump rebuild. Cleanliness is absolutely critical – any contamination will destroy new seals quickly. Replace all seals even if some look okay, since they’ve all endured the same service hours. Use assembly lubricant during installation and change your hydraulic filter and fluid afterward to remove any contamination.
