Highlights
Key Advantages
  • Covers the seals you actually replace during a full Cop1840 / Cop1840EX+ drifter overhaul—no rummaging through partial kits.
  • Uses OEM-spec rubber compounds that handle aggressive rock-drill oil temps and don't turn brittle in cold underground headings.
  • Stops oil weepage at the front head, piston area, and side bolts that leads to pressure drop and wasted hammer power.
  • Fits both surface top hammer rigs and underground jumbos without modification—same part, two very different job sites.
Use Cases
Applications
  • Top hammer surface drill rigs running Cop1840 drifters
  • Underground jumbo drills with Cop1840EX+ drifter units
  • Tunneling faces where downtime from seal failure costs metres per shift
  • Quarry benches drilling hard granite or abrasive sandstone
  • Contract miners keeping a spare overhaul kit on the shelf for scheduled maintenance

FAQ
FAQ
How do I know this kit fits the drifter I have on site?
If your drifter data plate says Cop1840 or Cop1840EX+, it's the right kit. The OEM number 3115924296 (3115 9242 96) matches what you'll find in the parts manual. Still unsure? Send us a photo of the plate and we'll double-check.
What’s actually inside? Am I getting just a few O-rings or everything I need?
You get the full set—seals, gaskets, and O-rings listed for a complete overhaul in the Epiroc parts book. Nothing less. You shouldn't need to hunt for extra seals once the drifter is apart.
How does this kit help when we’re drilling hard, abrasive rock?
Rock fines and dust eat seals fast. A fresh set keeps oil inside the hammer where it belongs and stops grit from getting into the piston area. That means the hammer holds its strike rate longer and you lose fewer metres per shift to soft-hitting or no-hitting.
I need this on a tight timeline. What are my shipping options?
We usually get orders out within 24 to 48 hours. Express freight is available for same-week jobs. Give us your address and deadline—we'll tell you straight up if it can land on time.
Are these the same seals that come from the factory, or aftermarket copies?
OEM Epiroc supply, not generic. Same rubber, same dimensions. You don't get the cracked lips or weird-fit issues that show up with copy parts after a few shifts at 200 bar.
