OEM 3115 3635 01 Epiroc Impact Piston 3115363501 3115363500 for cop 1838 1838hd+ 1838he+ Atlas Copco

Impact Pistons That Keep Your COP 1838 Drill Running

The 3115 3635 01 (part numbers 3115363501 and 3115363500) impact piston drops right into Epiroc COP 1838+, HD, HD+, and HE+ rock drills. No modifications, no surprises. It is built to the same dimensional and material specs your drifter expects — hard rock, long shifts, high percussion hours. We keep both variants on the shelf so you are not waiting on a container from overseas. And if you need side bolts, seal kits, chuck bushings, or a whole front head, we likely have those too.

FAQ
FAQ
3115363501 vs. 3115363500 — which one do I need?
Both pistons fit the same COP 1838 family. The difference is usually a minor revision or alternate supplier code. In practice, they are interchangeable. Still, it helps to have your drifter serial number or a photo of the old piston when you order. We can double-check against Epiroc’s parts bulletins.
What drill models does this piston fit?
It works in Epiroc COP 1838+, COP 1838HD, COP 1838HD+, and COP 1838HE+. Older Atlas Copco-branded COP 1838 drifters use the same piston — same part number, same dimensions.
Genuine Epiroc or aftermarket?
These pistons are manufactured to OE specifications but are not branded Epiroc. Think of it as same drawing, same steel grade, same heat treat — just without the logo. We warranty them for fit and performance under normal drilling conditions.
How fast can I get one on site?
Most orders ship within 1–2 business days from our warehouse. Air freight to major mining hubs usually adds 3–5 days. If you need a full rebuild kit or multiple sets, we’ll give you a realistic lead time before you commit.
I’m not 100% sure about the part number. Can you help?
Yes. Send us your drifter model, any numbers stamped on the old piston, or a few photos of the machine tag. Our parts desk cross-references daily — it usually takes one email to confirm.
Do you stock other COP 1838 parts?
We do — seal kits, guide sleeves, chuck bushings, side bolts, hydraulic motors, accumulators, and more. If you are doing a 500-hour or 1000-hour service, you can source most wear items from us in one shipment.
