Original Overhaul Kit of Atlas Copco RD18U in Sweden

Sweden is Atlas Copco's home market—the company's drilling heritage runs from the 1873 tunneling work in Stockholm through the modern Epiroc spinoff in 2018. Swedish mining contractors treat original overhaul kits with a specificity that reflects both proximity to the manufacturer and a long culture of precision maintenance record-keeping. At LKAB, Boliden, and the smaller Swedish hard-rock operations, maintenance records tie each overhaul kit batch number to the drifter serial number and the percussion hour count at installation. That traceability lets the maintenance team identify when a specific batch of kits underperformed versus historical baseline and feeds back to procurement decisions.

The Atlas Copco RD18U original overhaul kit—part number family 3115 9XXX XX—is manufactured to the same dimensional specifications as the first production run, including the bore-matched lip geometry and compound hardness that Atlas Copco's engineering team calibrated against the RD18U's specific cylinder bore finish specification. The kit also includes components not in the standard seal kit: a new piston guide ring, updated accumulator check valve O-ring, and the wiper ring that's often omitted from aftermarket 'seal kits.'

What Original vs. Aftermarket Includes: Comparison

The Swedish maintenance culture's insistence on original kits translates into a simpler maintenance decision at service time: the technician opens the kit, installs every component in it, and logs the batch number. No substitution decisions, no part-by-part compatibility checks. HOVOO supplies original-specification RD18U overhaul kits with full batch traceability for the Swedish and Nordic market.
