OEM seals, less downtime.

The Epiroc Cop1840 / Cop1840EX+ Overhaul Kit 3115924296 (also listed as 3115 9242 96) covers the seals, gaskets, and O-rings needed for a standard rebuild of these top hammer rock drills. It fits surface rigs like FlexiROC and PowerROC, plus underground jumbos. Made to Epiroc's own specs, the kit helps keep percussion steady, internal leaks in check, and drill hours up—even in gritty mine or tunnel conditions.

Highlights
Key Advantages
  • One kit replaces all critical seals in Cop1840 and Cop1840EX+ drifters — fewer partial teardowns later.
  • OEM-spec materials handle high-frequency hammering and temperature swings without early cracking.
  • Part numbers 3115924296 and 3115 9242 96 refer to the same factory-sealed overhaul kit.
  • Restores hydraulic and pneumatic tightness after worn seals start bleeding pressure.
  • Keeps impact energy consistent so you’re not losing penetration rate during a shift.
  • In stock for quick dispatch — no long waits that leave a rig parked idle.
Use Cases
Applications
  • Surface top hammer rigs: FlexiROC, PowerROC, and similar DTH/top hammer carriers running Cop1840-series drifters.
  • Underground jumbos spec’d with Cop1840 or Cop1840EX+, common in development and production drilling.
  • Quarry and open-pit benches where bench height and rock hardness demand reliable percussion seals.
  • Tunnel and civil works crews that rebuild drifters on-site to avoid sending units out for shop work.
  • Fleet maintenance programs standardizing on genuine Epiroc parts for predictable overhaul intervals.

FAQ
FAQ
Does this kit cover the Cop1840EX+ as well?
Yes. The same overhaul kit fits both the Cop1840 and the Cop1840EX+, since the seal arrangement is identical between the two variants.
Why are there two different part number formats?
3115924296 is the 10-digit Epiroc number. 3115 9242 96 is the same part written with spaces, often seen on older Atlas Copco labels or system printouts. You’ll receive a kit that matches both references.
What’s actually inside the kit?
You get the main piston seals, accumulator seals, O-rings, backup rings, and gaskets needed for a major rebuild. It’s intended for a full teardown, not just a quick reseal of the front end.
How fast does delivery usually take?
We ship from stock, so most orders go out the same or next working day. Transit times average 3–7 business days for the U.S. and Europe, a bit longer for remote sites—expedited options are available.
Is this a genuine Epiroc kit or aftermarket?
It’s genuine OEM, sealed in Epiroc packaging. If your maintenance plan or warranty requires factory parts, this meets that requirement.
