Pulley Wheel
The pulley wheel, part 3128 0784 30, guides a belt or cable around a fixed radius in an Atlas Copco assembly, and its groove profile is what actually keeps the belt tracking straight rather than the wheel's overall diameter. A groove worn out of profile lets the belt ride slightly off-center, and that small misalignment shows up as accelerated wear on the belt edge long before the pulley itself looks obviously worn. A pulley that no longer spins freely on its bearing converts rolling contact into sliding contact at the belt interface, which wears both the belt and the groove far faster than normal running would.

Bushing
Wear inside drilling equipment is directed onto bushings deliberately, so that a replaceable component absorbs it instead of the housing behind. This one performs that role under the combination that defines rock drill service: percussion shock, rotation and abrasive contamination acting at the same time rather than in turn. Running past the wear limit reverses the economics the design intends, moving clearance and load into parts with long lead times and high costs. Replacement against drilling hours is the standard approach. Ordering by the Atlas Copco reference matters, since similar bushings are not interchangeable across models. Stalroc quotes this part by number and ships worldwide to mining, tunnelling and quarrying contractors.
Back Head
The back head closes the rear of a rock drill, containing internal pressures and locating components within the housing. It sits at the end of the machine where percussion energy is generated rather than delivered, which makes its sealing and structural duty continuous rather than occasional. Damage or distortion here affects the alignment of what sits inside, so condition matters beyond the part itself. Where a drill is opened for overhaul, assessing the back head alongside the components it retains avoids reassembling a machine around a compromised housing. Recording the reference while the machine is apart saves searching for it under time pressure later.

Wiper
A wiper keeps contamination off a moving surface as it retracts, scraping dust, grit and water away before they are drawn into the assembly. It is a small component doing preventive work, and its failure is not felt directly — it is felt in the seals, bushings and bores that begin wearing faster once debris reaches them. Wipers are inexpensive and normally renewed whenever the assembly they protect is opened, which is the sensible practice given what they defend. Fitting a worn wiper back into a rebuilt assembly quietly undoes part of the work just completed. Because wipers are matched to the surface and groove they sit in, ordering against the manufacturer reference is the dependable route.

Spacer Sleeve
The spacer sleeve, part 3128 0494 00, maintains a fixed clearance between two components in an Atlas Copco assembly, and unlike a wear part it is not meant to lose material in service at all. Any measurable change in its dimension is usually a sign of incorrect loading elsewhere rather than routine wear. Reusing an old spacer sleeve during a repair, even one that shows no visible damage, risks a permanent set that leaves the reassembled joint slightly out of tolerance in ways that only show up later as premature wear on the parts either side of it. Stalroc quotes this Atlas Copco reference by part number and exports worldwide to mining, quarrying, and construction contractors.
Sliding Piece
A sliding piece provides a renewable bearing surface where one component moves against another, taking wear onto itself rather than onto the structure behind it. On drilling equipment the movement is usually accompanied by dust, grit and vibration, which is exactly the combination that wears sliding surfaces quickly and unevenly. Because this part is intended to be consumed, it belongs on a replacement schedule rather than in the reactive queue. Allowing one to run past its limit transfers the wear into components that are slower and costlier to obtain. Stalroc quotes this Atlas Copco reference by part number and exports worldwide to drilling contractors, with related wear items priced together where useful.
Turning Device
A turning device provides controlled rotational movement to a section of the machine, positioning equipment where the work requires it. Positioning mechanisms take load in more directions than their nominal duty suggests, because the mass they carry keeps moving after the input stops and every stop transfers that momentum into the mechanism. Wear introduces play, and play in a positioning system means the equipment no longer sits precisely where it was placed, which matters for accuracy at the face. Renewing before that slack reaches the mountings is the cheaper path. Stalroc quotes this Atlas Copco reference by part number and exports worldwide to mining, tunnelling and quarrying operations.
Hinge
A hinge carries the weight and movement of a panel or cover through repeated opening cycles, under vibration that works constantly against every fastening on the machine. Wear introduces play, play lets the panel move and rattle, and the resulting fatigue eventually reaches the mounting points rather than staying in the hinge. Renewing a worn hinge before it damages what it is mounted to is straightforward economics, and the check takes seconds during any routine inspection. Left long enough, the repair moves from a hinge to the panel and its mountings.

Lock
A lock secures a panel, cover or access point against vibration and the working environment, keeping what is behind it closed when it should be. On mobile plant that is both a security matter and a protective one: a cover that opens in service exposes components to dust, water and impact they were never meant to see. Locks are inexpensive and easy to overlook until one fails, at which point the exposure it was preventing begins immediately. Renewing it is a small job against the cost of contaminated equipment, and the check costs nothing during a routine walk-round. Because fitment is specific to the panel it closes, ordering against the manufacturer reference avoids a part that will not sit correctly.

Address Plug
An address plug configures how a control unit or module is identified within the machine's electrical system, allowing components to be recognised correctly when connected. It is a small item whose absence or incorrect fitment stops the system behaving as intended, regardless of everything else being sound. Faults of this kind can look like a failed control unit, which makes them an expensive misdiagnosis if the plug is not checked first. Because configuration is specific to the machine and its system, ordering against the correct reference is the only dependable route. Small electrical items like this are inexpensive to hold and disproportionately disruptive to be without.

Harness Wiring
A wiring harness bundles the machine's electrical connections into a single routed assembly, which is what makes replacement practical rather than a wiring exercise from scratch. Damage from vibration, chafing or moisture ingress tends to produce intermittent faults, and intermittent electrical faults consume more diagnostic hours than almost anything else on a rig. Where a section has already been repaired more than once, fitting the correct harness is generally faster and more reliable than continuing to chase it. Routing and connectors are machine-specific, so the reference matters. Stalroc supplies this Atlas Copco part against its manufacturer number and exports worldwide to drilling contractors.
Wiring
Signals and power reach a modern rig's systems through its wiring, and its condition determines whether the machine's electrical systems behave predictably. Vibration, abrasion, moisture and temperature cycling all attack cable and connections over time, and intermittent electrical faults are among the most time-consuming problems to trace on any machine. Replacing a damaged harness section is usually quicker and more certain than repeated repairs to it, particularly where the fault has already resisted diagnosis once. Ordering by the correct reference matters, since routing and connector arrangement are specific to the machine. Stalroc quotes this Atlas Copco part by number and exports worldwide.
