3115028800 Hydraulic Heavy Duty Piston Spare Parts for Drilling Drifter Epirco 3115 0288 00

Forged carbon steel piston that keeps your drill hammering shift after shift

3115028800 is a forged carbon steel hydraulic piston that drops right into Epirco drifter models calling for 3115 0288 00. We machine these to OEM specs so you don't deal with fitment headaches. The forging and heat treatment help it handle sustained high pressure without cracking early – a common pain point when cheap cast alternatives fail underground. Less piston swaps, less unplanned downtime in hard rock headings.

Highlights
Key Advantages
  • Forged carbon steel blank, not cast – better grain flow means it withstands impact fatigue longer than generic aftermarket pistons.
  • Machined to match Epirco 3115 0288 00 OEM tolerances, so installation is straightforward and sealing surfaces align correctly.
  • Induction hardened wear bands where it rides against guides – slows down galling and keeps clearance within spec over more hours.
  • Anti-corrosion coating that holds up in wet, acidic mine water – we've seen fewer returns from pitting compared to uncoated parts.
  • Direct interchange for common Epirco COP and similar drifter models – no shim stacks or mods required if your rig calls for 3115 0288 00.
Use Cases
Applications
  • Underground jumbos doing face drilling or bolt hole drilling
  • Surface track drills and down-the-hole setups where drifter hammer power matters
  • Quarry rock drills that run long shifts in abrasive dust environments
  • Replacement part for Epirco COP 1238, COP 1838, COP 2238 and related series
  • Heavy-duty drifters in tunneling and civil construction projects

FAQ
FAQ
Is this an original Epirco part?
No, it's an aftermarket replacement machined to the same print. It is not sourced from Epirco. We guarantee it matches the critical dimensions, material spec, and hardness of the 3115 0288 00 – we've been supplying mining wear parts for over a decade and we know what holds up.
Will it fit my Epirco COP 1838?
Very likely. The COP 1838 uses 3115 0288 00 as a factory piston. Check your parts book or the stamping on your old piston first. If you're unsure, send us your machine serial number and we'll confirm in a few hours.
What's the actual hardness of the piston?
You're looking at HRC 50-55 on the guide bands and seal groove areas, with a softer core around HRC 28-32 so it doesn't snap under shock loads. That's the same hardness window the OEM part is built to.
How fast can I get it if I'm in Australia or Canada?
Stock orders typically leave our warehouse in 2–3 business days. Air freight to major mining hubs usually takes 5–7 days door to door. Larger lots may take a bit longer – we'll give you a firm date before you commit.
Do you keep matching seal kits and front guides?
Yes, we inventory the seals, guides, side bolts, and even the rotation chuck bushings for this drifter series. One PO, one shipment, all the spares you need for a rebuild.
What if the piston fails under warranty?
We stand behind our parts with a 12-month warranty against material or workmanship defects. In the rare case of a problem, we'll replace it or credit you. We just ask for a quick failure report with photos so we can trace the root cause and improve.
