Circlip
The circlip, part 0335 2173 00, closes off one end of a bore to stop an internal component travelling further than its designed limit, working in tension rather than compression the way a snap ring on a shaft does. Fitting the wrong circlip in this position, even one that is only marginally undersized, lets the component it stops make repeated light contact with it on every cycle, which is what eventually throws it from the groove. Grooves themselves can wear from that repeated light contact, so a housing that has had a circlip pop out before is worth checking for groove wear rather than simply fitting another clip into it.

Shaft
The shaft, part 3115 0821 00, carries torque through a drifter's drive train under continuous load, with the shock of percussion superimposed on top of steady rotation. A shaft running slightly out of true rarely announces itself directly; instead it wears the bearings and bushings it passes through, so the shaft is often the last thing checked rather than the first even though it is frequently the underlying cause. Inspecting it during a scheduled overhaul, rather than after a bearing failure has already pointed at it, is the more reliable way to catch a shaft before it takes its neighbours with it.

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.

Rotation Chuck
The rotation chuck, part 3115 5313 80, is sized to a specific shank profile, and the fit between the two is what actually transmits torque rather than the chuck's outer dimensions, which is why a chuck that looks correct for a machine can still be wrong for the shank it is meant to grip. Fitting a mismatched chuck-and-shank pairing wears both faster than either would wear against its correct match, since the load concentrates on the few points of contact that do line up rather than spreading evenly. Confirming both references against the machine's parts manual before ordering either one avoids that kind of mismatch, which is easy to make when chucks from adjacent drifter generations look interchangeable.

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.

Valve Cover
The valve cover, part 3115 2077 03, encloses the valve chamber in a drifter's percussion circuit, holding internal pressure while keeping external dust and moisture away from a component that controls how the whole percussion cycle is timed. Because the cover is a static housing rather than a moving part, it is easy to assume it never needs attention, but a cover that has lost its sealing face lets contamination reach the valve it protects far more readily than any other entry point in the assembly. Checking the cover's sealing face whenever the valve beneath it is serviced costs little against the risk of contaminating a freshly rebuilt valve through a cover nobody inspected.

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.

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. Stalroc quotes this Atlas Copco reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
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.

Circlip
The circlip, part 0335 2169 00, retains a component axially inside its bore or on its shaft by seating into a machined groove, holding position without needing continuous clamping force the way a bolted joint does. A circlip that has lost its spring tension seats less firmly in the groove, and the play that introduces is often mistaken for wear in the component it is retaining rather than in the clip itself. Because it is inexpensive relative to what it holds in place, reusing a circlip through a rebuild to save a small cost is a poor trade against the part it is meant to protect.
