Atlas Copco Spare Parts
Compatible rock drill components for Atlas Copco — 118 parts listed
Screw
The screw, part 3161 0388 00, clamps a structural joint to a specified torque and, in a percussion drill, has to hold that clamp load through continuous vibration rather than a single static application. A generic fastener that matches the thread but not the specified grade will hold under static load on the bench and still back out or fatigue under the drill's actual duty cycle. Because the failure only appears under vibration rather than under a static check, substituting fastener grade on a percussion assembly is a false economy that usually surfaces as a loose or lost joint later.

Front Part
The front part, part 3115 2950 83, forms the leading section of the drifter where the shank adapter engages and the percussion impact is first transmitted into the drill string, making it one of the highest-load components in the whole assembly. Because it sits at the point where impact energy enters the string, wear here shows up as reduced transfer efficiency before it shows up as a visible fault, which is easy to mistake for a problem elsewhere in the rig. A front part run past its wear limit lets impact energy dissipate at the joint instead of transmitting into the rock, which is a loss in penetration rate that often gets attributed to the bit rather than the part causing it.

Temperature Sensor
The temperature sensor, part 9106 1856 02, feeds the control system the reading it uses to protect the rig from running hot, so its own accuracy is what the protection strategy actually depends on rather than the alarm threshold set in software. A sensor drifting out of calibration reports a plausible but wrong temperature, which either triggers unnecessary shutdowns or, more seriously, fails to trigger a real one. Because a drifting sensor still returns a reading rather than an obvious fault code, it is one of the harder components to catch without a periodic calibration check against a known reference.

Rotation Chuck
The rotation chuck, part 3115 2649 00, grips the shank adapter and transmits both rotation and percussion into it, which means any wear in its grip shows up as lost energy in two different directions at once rather than just one. A chuck that has opened up slightly still turns the shank, so rotational function alone is not a reliable test of its condition; the grip on percussion transfer degrades first and is harder to notice from the cab. Because the chuck sits directly in that dual load path, its wear accelerates whatever it grips, which is why it is usually assessed alongside the shank whenever either is due for inspection.

Needle Bearing
The needle bearing, part 0516 1538 00, carries radial load in a position where there is not enough room for a standard roller or ball bearing, packing more rolling elements into the same envelope to spread the load across a larger contact area. That density is also what makes it intolerant of contamination: a single piece of grit trapped between the needles marks every one of them on the next revolution rather than just the one it lodged against. Because of that sensitivity, a needle bearing removed from a contaminated housing is rarely worth reusing even if it still turns freely by hand.

Driver
The driver, part 3115 2650 00, transmits rotation through a splined connection inside a drifter's drive train, and spline wear here tends to run unevenly across the tooth profile rather than uniformly, since only part of each tooth carries load under any given direction of rotation. Measuring backlash at a single point can therefore miss wear concentrated elsewhere on the same spline, which is why a driver suspected of wear is better checked across its full tooth profile than at one spot. Because backlash converts to hammering the instant the machine reverses direction, a driver worn on one face of its splines often fails sooner than its measured backlash alone would suggest.

Overhaul Kit
The overhaul kit, part 3115 9242 97, covers the wear parts for a full drifter strip-down rather than one stage of it, spanning seals, bushings, guides and rings across the whole machine instead of a single mechanism within it. Ordering to that scope from a parts book, item by item, is where a full overhaul most often overruns its budget of time, usually on components that only become obviously needed once the machine is already in pieces. Because the kit is scoped to the whole drifter, it is worth confirming against the specific model and generation being overhauled rather than assumed interchangeable with a kit for a similar-looking machine.

Flushing Head
The flushing head, part 3115 2121 00, connects the drifter to the rotating shank and carries flushing medium through that joint under both pressure and rotation at once, which is a harder duty than a static flushing connection sees elsewhere in the circuit. Wear at this rotating interface shows up first as flushing medium escaping past the joint rather than reaching the bit, which crews sometimes mistake for a supply problem further back in the circuit. Checking the joint itself before tracing the fault further upstream saves time on a symptom that is more often local to this connection than it first appears.

Connection
The connection, part 3115 1938 00, couples two sections of a drifter's hydraulic circuit at a joint that is disturbed every time the machine is serviced, which makes it more exposed to thread damage and seal wear than a connection nobody ever opens. Cross-threading on reassembly is the most common way a fitting like this actually fails, and it usually shows up as a slow weep at the joint rather than as a fitting that visibly will not tighten. Renewing the sealing face at this connection whenever it is disturbed, rather than assuming the old one will seat again, is the more reliable habit.

Side Bolt
The side bolt, part 3115 2113 00, clamps two housings together from the side of a drifter rather than through the main body, carrying shear load across the joint face in addition to the clamping tension the bolt itself provides. Because the load is shear as well as tension, a side bolt that has stretched slightly lets the housings creep against each other under vibration even while the bolt still measures within its length tolerance. Side bolts are normally renewed as a full set rather than one at a time, since a single stretched bolt in an otherwise fresh set concentrates load onto itself and stretches faster than it would have as part of a uniformly worn set.

Seal Housing
The seal housing, part 3115 2766 80, holds the seal stack in the correct order and orientation at its position in the drifter, which matters because a wiper, primary seal and back-up ring fitted out of sequence fail far sooner than the same seals fitted correctly. A housing that has taken a knock or corroded slightly changes that seating geometry even when the seals themselves are new, which is a common reason a freshly reseal drifter still leaks at the same point. Inspecting the housing bore and face, not just replacing the seals inside it, is what actually resolves a repeat leak at this position.

Washer
The washer, part 3115 0823 00, spreads clamping load across a joint face on an Atlas Copco drifter, and because that joint sits somewhere the machine vibrates continuously, the washer is doing more work than an equivalent washer would in a static assembly. A washer reused through several strip-downs develops a compression set that reduces how much bearing area it actually presents to the joint, even though its outer dimensions look unchanged. Renewing washers with the fasteners they sit under, rather than treating them as a reusable spacer, keeps the joint clamping the way it was designed to.
