3115101093 motor seal kits Epiroc repair parts cop 1838 1840 Atlas Copco rock drifter 3115 1010 93

Seal kit 3115101093 for COP drifters – keeps oil in, contamination out.

The 3115101093 seal kit drops straight into the motor section of Epiroc COP hydraulic drifters – no modifications, no guesswork. This kit covers COP 1838, 1840, 1238, 1440, 1850CR, and 2550 models. Seals are made from nitrile and fluoroelastomer compounds that handle the heat and pressure of underground and surface drilling. What you get: fewer oil leaks, less unexpected downtime, and longer stretches between rebuilds. If your drifter is weeping oil or pressure's dropping, this kit replaces everything needed to seal the motor end properly.

  • Tunnel reinforcement – bolting rigs running COP 1238 or 1440 drifters in wet conditions.
  • Drifter rebuild programs – motor seal replacement every 800–1000 percussion hours as part of your PM schedule.
  • Emergency liner swap when a failed seal is causing low blow energy or erratic rotation.

FAQ
FAQ
Will this 3115101093 kit fit my COP 1838ME?
It fits standard COP 1838 and 1840 variants. For the 'ME' or 'CR' sub-types like 1838CR or 1850CR, it also works – but always cross-check with your unit's parts list, especially if the drifter was rebuilt with non-standard components before.
Is this a genuine Epiroc kit or a third-party copy?
Genuine Epiroc OEM, sealed in factory packaging. We don't mix aftermarket seals; everything matches the original spec sheet and material callouts.
How do I know if my motor seals are gone?
Common red flags: oil collecting around the motor section or blowing down the drifter, percussion pressure dropping without a visible external leak, or hydraulic oil turning milky from water ingress. If you're losing oil but can't find a pinhole in your hoses, the motor seals are the first place to look.
Can I change the motor seals without sending the drifter to a shop?
Most site crews handle it in a clean bay. The motor end comes off without pulling the entire drifter from the feed. Basic drifter tooling, a clean workbench, and the OEM torque specs are all you need. Usually plan 3–4 hours for two guys.
How often should these seals be replaced?
We see best results swapping them at 800–1000 percussion hours, or alongside the percussion piston inspection. If your water pressure is erratic or you're drilling in abrasive mud seams, check them closer to 500 hours. They're cheap insurance against a scored cylinder or motor bushing.
Do you keep these in stock, or is there a lead time?
We stock 3115101093 kits in three warehouses. Most orders ship within 24 hours. For Western Europe and North America, you'll typically have them in 2–4 working days. Africa and CIS typically 4–7 days. We can also hold kits on consignment if you're running a predictable rebuild cycle.
