3115504312 CONNECTING PLATE ATLAS COPCO (3115 5043 12)
If you’re rebuilding or maintaining an underground drilling system, small structural interface parts can decide whether the whole machine runs smoothly or starts “walking” out of alignment under vibration. The 3115504312 Connecting Plate Atlas Copco is one of those critical interfaces: a precision-machined connecting plate that helps hold components in position, keeps mating parts aligned, and supports stable operation in demanding rock drilling conditions.
In real sites, a connecting plate is rarely “just a plate.” It is a load path. It is a locator. It is the quiet part that makes the noisy parts behave. The 3115504312 Connecting Plate Atlas Copco is designed to sit between connected elements of the assembly and maintain geometry under cyclic stress, impact pulses, and hydraulic vibration, exactly the kind of environment where loose tolerances and weak finishes fail early.
we supply the 3115504312 Connecting Plate Atlas Copco as an OEM-spec replacement part for international customers who need fast, dependable fulfillment. We ship worldwide in 5 working days, supporting mining and construction operations that cannot afford downtime.
What the 3115504312 Connecting Plate Atlas Copco does in the system
A connecting plate’s job is to keep multiple components acting like one stable structure. The 3115504312 Connecting Plate Atlas Copco functions as a rigid interface point, helping prevent micro-movement that can cause:
Misalignment in mounted components
Uneven wear on pins, bushings, and mating faces
Noise and vibration amplification
Premature loosening of fasteners
Stress concentration and cracking in neighboring parts
Because rock drilling creates repeated shock loading, even tiny shifts compound quickly. The 3115504312 Connecting Plate Atlas Copco helps protect the wider assembly by spreading forces across a broader surface area and keeping the contact faces seated as designed.
From the images, the part shows a heavy, machined body with a cylindrical sleeve/boss feature and dual through-holes for mounting. That geometry strongly suggests an alignment + mounting role, where the boss supports accurate positioning while the bolt holes clamp the plate into the structure.
When you install a correctly made 3115504312 Connecting Plate Atlas Copco, you’re not only replacing a worn component, you’re restoring the designed geometry that keeps the rest of the system working in-spec.
Why this component matters in rock drilling environments
Underground and surface rock drilling systems don’t fail politely. They fail by vibration, heat, contamination, and repeated impact. In that context, the 3115504312 Connecting Plate Atlas Copco matters because it supports:
Dimensional stability under shock
Rock drills create high-frequency impact cycles. If the interface plate flexes or creeps, bolt preload changes, mating surfaces fret, and cracks can initiate. A properly machined 3115504312 Connecting Plate Atlas Copco helps reduce these risks by maintaining rigidity where it counts.
Alignment that protects wear parts
When the interface geometry is correct, load transfers as intended. That means bushings wear evenly, pins stay seated, and adjacent components aren’t forced to “compensate” for an out-of-square connection. Over time, this can noticeably reduce secondary failures.
Predictable serviceability
Maintenance teams need parts that fit without drama. A correctly produced 3115504312 Connecting Plate Atlas Copco supports repeatable assembly: holes line up, contact faces seat, and torque specs actually hold.
Construction and design features of the 3115504312 Connecting Plate Atlas Copco
While exact material grades and dimensions should be verified by the machine manual and serial-specific parts book, a quality OEM-spec 3115504312 Connecting Plate Atlas Copco generally reflects the functional needs seen in the component design:
Precision-machined mounting faces
Flatness and parallelism matter. A connecting plate that rocks on its seat or has uneven faces will never clamp correctly. The 3115504312 Connecting Plate Atlas Copco is built to sit flush so bolt preload is distributed, not concentrated.
Robust mounting holes for secure fastening
The two large side holes shown in the images indicate mounting points designed for stable clamping. On drilling equipment, this is essential to prevent the gradual loosening caused by vibration.
Cylindrical boss/sleeve section for alignment
The protruding cylindrical section appears to act as a locating feature or interface sleeve, helping ensure that connected parts align concentrically and maintain stable positioning. This is exactly the type of geometry that turns a “plate” into a true connector.
Protective coating/finish
The dark surface finish suggests a protective coating intended to resist corrosion and surface wear in harsh environments. Underground applications often involve moisture, dust, and chemical exposure, so surface protection isn’t cosmetic; it’s life extension.
Benefits of choosing the 3115504312 Connecting Plate Atlas Copco (OEM-spec replacement)
When you select the 3115504312 Connecting Plate Atlas Copco for service work, you’re buying back stability. The practical benefits usually show up as:
Reduced vibration-related loosening
A stable interface helps fasteners keep their preload longer. That means fewer re-torque cycles and less “mystery movement” during inspections.
Lower risk of cascading wear
Misalignment can destroy expensive components indirectly. The 3115504312 Connecting Plate Atlas Copco helps protect neighboring parts by keeping the assembly geometry correct.
Cleaner rebuilds, faster installation
Parts that fit right reduce install time and reduce rework. In the field, that’s money. In underground operations, it’s also safety and scheduling.
More consistent drilling performance
When mechanical interfaces stay aligned, performance tends to be more consistent: less chatter, fewer unusual noises, and less heat generated by friction where friction shouldn’t exist.
Part numbers and search visibility: use both formats
For purchasing, stocking, and cross-referencing, it’s smart to use both part number formats:
3115504312 Connecting Plate Atlas Copco
3115 5043 12 Connecting Plate Atlas Copco
Some catalogs and sellers format Atlas Copco / Epiroc numbers differently. The 3115504312 Connecting Plate Atlas Copco and 3115 5043 12 Connecting Plate Atlas Copco references point to the same component listing in multiple sources.
Compatibility: Which Atlas Copco / Epiroc models use this part
Based on publicly available parts listings, the 3115504312 Connecting Plate Atlas Copco is shown as suitable for:
Epiroc / Atlas Copco underground drilling: Boomer S1D
Epiroc / Atlas Copco drifter-related references: COP 1638HD+, COP 1838HD+, COP 2238HD+
Important practical note: drilling equipment configurations vary by build, serial range, and installed options. So treat the list above as a strong starting point, then confirm with the machine serial number and the parts manual before final installation, especially if your assembly has been modified in previous rebuilds.
Typical use cases for the 3115504312 Connecting Plate Atlas Copco
The 3115504312 Connecting Plate Atlas Copco is commonly ordered during:
Planned rebuilds and overhauls
When you’re already disassembling major components, replacing structural interfaces is a smart move. It restores the assembly geometry and reduces “return-to-shop” failures.
Vibration and looseness troubleshooting
If your team notices repeated loosening, fretting marks near interfaces, unusual vibration, or alignment drift, replacing worn interface parts like the 3115504312 Connecting Plate Atlas Copco can be part of the corrective plan.

fasteners and washers (when stretch or thread wear is suspected)
bushings or sleeves that show scoring or oval wear
mating brackets that have fretting marks
nearby seals (if disassembly exposes them)
Technical details and specifications (practical, field-focused)
Exact dimensions and tolerances should be confirmed in the OEM parts documentation for your machine. However, these are the most useful, real-world “spec” checkpoints technicians use when handling the 3115504312 Connecting Plate Atlas Copco:
Functional characteristics to verify
Mounting hole condition: roundness, edge integrity, and surface contact
Flatness of the seating faces: no rocking on a flat reference
Boss/sleeve integrity: no scoring, dents, or deformation
Coating condition: no deep rust pitting or peeling near contact faces
Threaded areas (if present): clean engagement and no cross-thread damage
Approximate net weight
A published listing shows the weight as 1.5 kg for this part reference.
Practical note: packaged shipping weight may be higher depending on boxing and protective materials, but for inventory planning and internal BOMs, 1.5 kg is a useful baseline for the 3115504312 Connecting Plate Atlas Copco.
Installation guidance for the 3115504312 Connecting Plate Atlas Copco
Below is a safe, field-usable installation approach that fits most connector/plate interfaces on drilling rigs. Always follow the machine’s service manual torque values and lock procedures.
1) Prepare the work area and lockout
Isolate hydraulic pressure (lockout/tagout).
Clean the work zone to prevent contamination entering open interfaces.
Support the connected components to prevent load shift during removal.
2) Remove the existing plate and inspect mating surfaces
Mark the orientation before removal (photo + paint mark).
Remove fasteners in a controlled pattern to avoid sudden movement.
Inspect the mating faces for fretting (fine metallic dust), scoring, or high spots.
3) Clean and correct the mounting interface
Use a non-aggressive cleaning method first (solvent + lint-free wipes).
If needed, lightly dress burrs, do not remove material from critical faces beyond what the manual allows.
Confirm that the mounting face is flat and free of debris.
4) Test-fit the 3115504312 Connecting Plate Atlas Copco
Confirm bolt holes align without forcing.
Confirm the boss/sleeve seats correctly into the mating feature.
Ensure the plate sits flush, no visible gap.
5) Install fasteners and torque correctly
Use the correct grade fasteners per the manual.
Apply thread treatment only if specified (some assemblies require dry torque).
Torque in stages using a cross pattern to seat the plate evenly.
6) Re-check after initial run-in
After the first operating period, re-check torque or clamp condition if the manual recommends it. In high-vibration environments, a post-install inspection is cheap insurance.
Maintenance tips to extend service life
The 3115504312 Connecting Plate Atlas Copco will last longer when the surrounding system stays healthy. The best habits are:
Keep fastener integrity high
Loose bolts turn a plate into a grinder. Always investigate why fasteners loosen (vibration, wrong torque, damaged threads, mating face contamination).
Watch for fretting marks
If you see fine dust, polished rubbing patches, or “smoking” around interfaces, the plate may be moving. Address it early before the movement damages larger components.
Control contamination
Dust and moisture accelerate surface wear and corrosion. If your operation is wet, consider adding maintenance steps around cleaning and inspection frequency.
