3115505002 Impact Piston Guide front Cop1638hd+ Cop1838hd+ Epiroc drill drifter part 3115 5050 02

Keeps Your Drifter Hammering Straight – Shift After Shift

The Epiroc 3115505002 piston guide front is the same part that ships inside Cop 1638hd+ and 1838hd+ drifters from the factory. Its job is simple: keep the piston moving dead center through every blow, so you don't chew up seals, bushings, or the cylinder bore.

What matters in the field:

  • Case-hardened alloy holds its shape under constant percussion – less slop, fewer teardowns.
  • Bore and faces are ground to factory tolerances, so lubrication film stays intact and heat doesn't build up.
  • Drops straight in with no filing, no shimming – same fit as the part you're pulling out.

FAQ
FAQ
Will this guide fit my drifter if I'm not sure about the model?
Check the metal tag on your drifter housing. If it reads Cop 1638hd+ or Cop 1838hd+, this guide fits. You can also match the part number from your service manual – we ship under both 3115505002 and 3115 5050 02.
How do I know this isn't an aftermarket copy?
Every guide comes in sealed Epiroc packaging with factory labels and batch numbers. We source directly from Epiroc distribution, no middle men, no reboxed knock-offs.
What's a realistic lead time to a mine site in Australia or Canada?
If it's on our shelf, it goes out same day or next morning. DHL/FedEx priority usually lands it in 3–5 working days to major mining hubs. Remote sites may add a day or two. We'll confirm exact ETA before you pay.
When do I actually need to swap this guide – not just the manual interval?
Look for scoring inside the bore, or a wear ridge you can catch with a fingernail. If percussion starts drifting or you see brass from the piston getting into the oil, the guide is done. Many crews bag it at 800–1000 hours regardless to stay ahead of unscheduled downtime.
