OEM front guide sleeve for Cop1638hd+ & Cop1838hd+ – stock ready to ship

Epiroc 3115505002 Front Piston Guide Sleeve is an original factory part for Cop1638hd+ and Cop1838hd+ hydraulic rock drills. In hard mining and tunneling jobs, it puts the piston exactly where it belongs—centered, stable, and transferring energy cleanly. That means less sideways wear on the cylinder bore and seals, fewer unexpected failures, and predictable service life.

  • Part Number: 3115505002 (also listed as 3115 5050 02)
  • Drill models: Cop1638hd+, Cop1838hd+
  • Brand: Epiroc – OEM manufactured to original specs
  • What it does: Guides the piston front end, keeps alignment tight, reduces vibration and metal-to-metal scuffing

Highlights
Key Advantages
  • OEM spec right out of the box: no shimming, no modifying to fit Cop1638hd+ or 1838hd+ housings
  • Tight bore tolerances hold piston runout to a minimum, so seals don’t get chewed up prematurely
  • Hardened alloy steel takes impact cycles and abrasive slurry without mushrooming or cracking
  • Backed by Epiroc’s traceability, so you know exactly which batch it came from and when
  • Stocked locally and ready to go—get it on site fast instead of waiting on long lead times.
Use Cases
Applications
  • Production drilling underground with Cop1638hd+ drifters on long-hole rigs
  • Tunnel face drilling and cross-cut development running Cop1838hd+ hammers
  • Swap-out during planned drifter overhauls, typically when the piston comes out
  • Civil tunneling and mine development where water and muck are constant, but downtime isn’t an option
  • Fleet maintenance: keep a spare on the shelf for quick turnarounds between shifts

FAQ
FAQ
Does the 3115505002 sleeve fit both Cop1638hd+ and Cop1838hd+ without modifications?
Yes. It’s the same OEM front guide sleeve used on both models from the factory. Always double-check your drill’s serial number if it’s an older unit.
How do I know when the front guide sleeve needs changing?
A few warning signs: impact noise changes, penetration speed drops, you see scoring on the piston, or find bronze-colored fines in the hydraulic oil. On a teardown, measure the inner diameter—if it’s past the wear limit in the manual, replace it before it takes out the piston or cylinder.
Is this sleeve from Epiroc directly or an aftermarket copy?
Straight from Epiroc’s supply chain with full paperwork. Not a copy, not re-boxed. Every sleeve comes with traceability to the manufacturing batch.
Will this help if I’m seeing premature piston or seal failures?
Often, yes. A worn or poorly aligned guide sleeve lets the piston drift off-center. That loads up seals unevenly and causes metal pick-up on the piston. Putting in a fresh OEM sleeve brings the alignment back to spec and can stop that failure cycle.
What’s the lead time if I need one right away?
We carry stock in our regional warehouse. Most orders in major markets go out same day. International deliveries usually land in 3–5 business days with express shipping. If it’s a breakdown, call us—we’ll prioritize it.
