Service requirements for COP 1840 can range from an individual wear item to a broader repair package. In workshop overhaul work where internal wear, sealing condition and mating surfaces determine the real repair scope, the useful approach is to identify the exact machine and component first, then group related parts only when the workshop confirms they belong to the same maintenance event.
Worldwide Supply
International delivery support for planned maintenance and urgent repair requirements.
Correct Part Identification
Part number, machine model and serial information are checked before quotation whenever available.
Fast Commercial Response
Clear quotation support for individual components, repair kits and complete parts lists.
For this maintenance scenario, begin with pistons and striking parts, then review hydraulic service items and wear hardware according to the actual repair scope. The order is intentionally model-specific: confirmed workshop findings should decide what is purchased rather than copying a standard list from another Atlas Copco / Epiroc machine.
One condition worth investigating on COP 1840 is visible gear or spline damage. Technicians should check tooth contact, lubrication, alignment and mating drive components before the purchasing list is finalised. A symptom is useful evidence for inspection, but it should not be treated as proof that one particular component is the only cause.
For planned service, inspect mating surfaces before installing a new wear component. It is also useful to record operating hours and unusual symptoms before the planned shutdown. These steps give purchasing better identification data and help the workshop avoid discovering an unverified related item after the machine has already been opened.
Send the COP 1840 part numbers you can confirm, quantities, available machine or serial information and destination country. Mark uncertain references clearly and include readable photos of markings or component position when identification is still required.

Brand: Atlas Copco / Epiroc | Equipment Type: Hydraulic Drifter and Rock Drill Equipment | Application: Mining, tunneling, quarrying and top hammer drilling | Support: Parts identification and export-oriented replacement supply
We support replacement part sourcing for Atlas Copco / Epiroc COP 1840 hydraulic drifter and rock drill equipment used in mining, tunneling, quarrying and top hammer drilling applications.
Our supply scope may include impact assemblies, rotation components, shank adapter areas, sealing systems, hydraulic circuits, wear parts and drilling transmission components, selected according to machine model, component group, operating environment and maintenance requirement.
Atlas Copco / Epiroc COP 1840 equipment operates in high-impact rock drilling environments where percussion energy, rotation load, vibration and abrasive dust require accurate maintenance planning. Correct part identification is important during preventive maintenance, overhaul operations and urgent repair planning.
Replacement support is available for drilling contractors, mine operators, service workshops and industrial distributors that require reliable sourcing for hydraulic drifter systems, top hammer drilling equipment and rock drill machine groups.
The Atlas Copco – Epiroc COP 1840 rock drill is engineered for intensive drilling operations where power stability and mechanical accuracy are critical. In such demanding conditions, using the correct replacement parts plays a key role in protecting the machine and maintaining consistent drilling output.
We supply a specialized range of COP 1840 replacement parts, including internal rock drill components, wear-resistant parts, sealing elements, and precision-machined assemblies. Each part is selected to ensure full compatibility with the original design of the COP 1840.
All spare parts are manufactured in accordance with OEM or equivalent technical standards, helping reduce vibration, heat buildup, and premature wear. This results in longer service life, fewer unplanned shutdowns, and improved operational efficiency in hard rock environments.
Our technical experience allows us to support customers not only with parts supply but also with correct part identification and application guidance. With strong stock availability and fast logistics, we help minimize downtime and keep drilling projects on schedule.
For reliable Atlas Copco – Epiroc COP 1840 replacement parts and professional support, contact us today and secure long-term performance for your drilling equipment.
Export-oriented supply assistance is available for mining contractors, drilling equipment operators, service companies and industrial distributors across Europe, North America, South America, Africa, Asia and Oceania.
The Atlas Copco / Epiroc COP 1840 page should be understood as a technical reference for hydraulic rock drill replacement parts, not only as a spare part list. In top hammer drilling, impact performance, rotation stability, flushing quality and hydraulic sealing all affect each other. A problem in one component group can quickly create secondary wear in nearby systems.
The supplied COP 1840 catalogue is used here as a reference for the engineering structure of this rock drill family. It shows a rock drill system organized around accumulator groups, return accumulator, hydraulic motor options, seal kit, O-ring set, charging device, overhaul kit and cross-reference logic. The exact compatibility of each part must still be confirmed by the actual part number and machine configuration.
A hydraulic rock drill is not a collection of independent components. Hydraulic pressure drives the impact mechanism, the rotation drive transfers torque to the shank adapter area, the front head guides the drill steel and the flushing circuit removes cuttings from the hole. The reliability of the complete drill depends on the balance between these functions.
The impact section works through controlled piston movement and hydraulic valve timing. Piston guides, valve components, seal housings and damping components must remain within service limits to preserve percussion efficiency. When oil contamination or seal wear increases, the drill may show lower impact energy, unstable sound, heat generation or repeated leakage.
The rotation system links hydraulic motor output with the drill steel connection. Bearings, gear wheels, shafts, bushings, couplings and rotation chuck components are exposed to combined torque, impact vibration and side load. Wear in the rotation path may cause backlash, poor hole accuracy and accelerated bearing fatigue.
The front head area guides the shank adapter while supporting flushing flow. Cup seals, guide components, flushing head surfaces and stop rings help control water flow and reduce abrasive contamination. If the front guide area becomes worn, the drill may develop abnormal vibration, leakage or uneven wear on the shank adapter.
Seal kits and O-ring sets are central to the service life of hydraulic rock drills. They protect oil pressure, prevent external leakage and limit contamination transfer between hydraulic and flushing sections. Replacing seals without checking guide wear, bearing condition or pressure instability may lead to repeated failure.
| Observed Condition | Possible Cause | Inspection Focus |
|---|---|---|
| Lower penetration rate | Impact pressure loss or accumulator instability | Accumulator, valve system, piston guides |
| Hydraulic oil leakage | Seal wear, O-ring damage or surface scoring | Seal kit, seal housing, front head interfaces |
| Rotation backlash | Bushing, bearing or rotation chuck wear | Rotation drive, gear housing, driver |
| Overheating | Internal leakage, friction or contaminated oil | Hydraulic circuit and wear surfaces |
| Abnormal vibration | Misalignment, worn guide or bearing fatigue | Front head, guide, shaft and bearing areas |
Correct part identification for COP 1840 should use the part number, component description, hydraulic drill model and available machine information together. Similar-looking hydraulic drills may contain different internal assemblies, seal dimensions, motor options or overhaul components. Vomeks supports international inquiries by checking part numbers and technical descriptions before quotation.
