3115915096 Atlas Copco COP1838ME COP1838HD Hydraulic Rock Drill Seal Kit

Heavy-Duty Hydraulic Rock Drill Seal Overhaul Kit for Atlas Copco / Epiroc COP 1838ME & COP 1838HD Drifters | OEM Part: 3115915096

Maximum Penetration Power for Hard-Rock Mining & Drifting

The Atlas Copco / Epiroc COP 1838ME and COP 1838HD hydraulic rock drills are industry benchmarks for high-frequency percussive output in tunneling and underground mine development. Operating under thousands of impact cycles per minute, relentless hydraulic pressure surges, and continuous quartz dust contamination, dynamic seals inside the drifter housing endure severe mechanical stress.

When dynamic seal lips degrade, fluid bypasses internal dampening and striking chambers, leading to reduced penetration speeds, elevated system temperatures, and hydraulic oil weeping past the front shank nose. Rebuilding your drifter housing with our 3115915096 Service Seal Kit restores original hydraulic containment, prevents oil contamination, and maximizes drifter uptime.

Key Hydraulic Protection & Material Features

• High-Modulus Polyurethane (TPU) U-Cups: Retains dynamic lip memory and radial elasticity under continuous mechanical vibration without tearing or hardening.

• High-Temp Viton (FKM) Back-up Energizers: Maintains static and dynamic seal pressure during severe hydraulic oil heat spikes in enclosed face headings.

• Bronze-Filled PTFE Guide Rings: Provides low-friction guidance along moving components, preventing scuffing, dampening chatter, and stopping cross-chamber fluid bypass.

• Heavy-Duty Scraper Wiper: Actively strips away quartz dust, drill slurry, and wash-down water before foreign particles penetrate the main housing gland.

Field Service & Rebuild Guidelines for Mine Mechanics

💡 Jobsite Maintenance Tip:

High-frequency percussive drifters require strict cleanliness during seal overhauls. When replacing seals using the 3115915096 kit, thoroughly clean all gland cavities in a clean solvent bath. Inspect the driver bushings and striking bar (shank adapter) contact surfaces for ovalization or grooving. Installing fresh dynamic seals over worn bushings will lead to rapid wiper cutting and premature fluid leaks.

Q&A

• Q: Is part number 3115915096 compatible with both COP 1838ME and COP 1838HD models?

  A: Yes. Part number 3115915096 / 3115 9150 96 is specifically engineered to fit both the COP 1838ME and COP 1838HD rock drill housing configurations across Atlas Copco and Epiroc brand designations.

• Q: What primary symptoms indicate that a COP 1838 series drifter requires a seal overhaul?

  A: Key indicators include a drop in penetration velocity (reduced striking force), visible hydraulic fluid weeping around the front housing, elevated oil running temperatures, or severe hose pulsing caused by internal pressure bypass.
