Cop 2550ux+ 3115924490 Seal Kit Minor Epiroc 3115924491 Major 3115924494 Drifter Motor Repair Kit

Less wrench time, more hammer time.

This isn't a random box of seals. It's the COP 2550UX+ service trio our mining and tunneling customers keep on the shelf—seal kit 3115924490, minor PM 3115924491, and the major drifter motor repair kit 3115924494.

Everything lands pre-sorted by maintenance interval. No chasing individual part numbers when a shift depends on getting that drifter back into the drift. Seals, O-rings, gaskets, motor components—all in one go.

Why crews stock all three:

  • One part number per service window, zero guesswork
  • Motor seals included in the major kit—often overlooked until there's a leak
  • Ready to throw in a service truck and head underground

Highlights
Key Advantages
  • Covers minor 800 h and major 1600 h intervals for COP 2550UX+ drifters – both T45/T51 and TDS 76 shank versions
  • 3115924494 major kit actually includes the drifter motor seals, not just hammer components
  • Pulled from the same material specs as OEM: nitrile, polyurethane, PTFE where the factory calls for it
  • Individually bagged and tagged per kit so the crew doesn't mix up parts mid-rebuild
  • Held in local stock – typical dispatch window is hours, not weeks, when a heading is waiting
Use Cases
Applications
  • Jumbo face drilling in hard rock mines – where a downed drifter costs more than the drill string
  • Civil tunnel crews running multiple COP 2550UX+ units on long headings
  • Quarry benches moving to hydraulic tophammer for better penetration rates
  • Component overhaul shops rebuilding drifters for rental fleets and contractors
  • Remote projects that need a complete drifter service kit rather than a pallet of loose bags

FAQ
FAQ
What exactly does the 3115924490 seal kit cover?
It’s the basic hydraulic seal set—O-rings, gaskets, shaft seals you swap out when the drifter starts weeping oil or loses hammer pressure. This is what most crews grab first.
Why buy the minor and major kits together?
The minor kit (3115924491) handles the 800-hour service. At 1600 hours you’ll want the major kit (3115924494) which adds the drifter motor seals, so you’re not stuck waiting for parts mid-job. Having both means one order, one shipment.
Are these OEM parts or aftermarket?
Quality aftermarket built to Epiroc specs. Same rubber compounds, same tolerances. Our mining customers run them side by side with OEM and don’t see difference in seal life.
How fast can I get these if a drifter goes down?
Most COP 2550UX+ kits are on the shelf. We typically ship same day if ordered by noon local time. Express freight can reach most mining hubs in 1–3 days.
Do you supply installation guides?
Yes—we can send digital copies of the assembly schematics and torque specs. Just mention it when you inquire, and we’ll attach the PDFs.
