Bolt
Fasteners in a percussion machine live a harder life than their appearance suggests. Every impact cycle tries to loosen them, and a bolt that backs off slightly allows movement between clamped faces, which then wear and make the joint impossible to tighten properly again. Correct replacement rather than reuse is the cheap insurance here. Workshops that reuse fasteners through several rebuilds tend to discover the cost later, in fretted mating surfaces on far more expensive castings. Ordering the correct Sandvik reference keeps the joint behaving as the machine's designers intended. Stalroc quotes this part by number alongside the larger components it secures, so a rebuild kit can be assembled in a single enquiry.
Piston
The piston, part 302 969 08, delivers repeated impact through a Sandvik percussion mechanism, so unlike a static hydraulic piston it has to survive shock loading on every stroke rather than just steady pressure. Fatigue cracking under that kind of repeated impact develops from the inside out, which means a piston nearing the end of its life can look completely sound right up until sudden failure. Impact energy that isn't transferred cleanly into the tool being driven reflects back into the piston itself, so misalignment elsewhere in the mechanism tends to shorten piston life even though the piston is not where the underlying problem is. Stalroc quotes this Sandvik reference by part number and exports worldwide to mining, quarrying, and drilling contractors.
Rotation Shaft
The rotation shaft carries turning force through the drill's rotation unit under continuous torque, with percussion shock passing through it at the same time. That combination is demanding: a shaft that is fatigued but not yet broken can still cause misalignment that wears bearings and bushings around it well before anyone suspects the shaft itself. Inspection during scheduled overhauls is the practical safeguard, since failure in service usually means an unplanned strip-down and a rig standing idle while parts are located. Recording the reference from the machine's parts manual at that point saves repeating the search later. Stalroc quotes this Sandvik part by its manufacturer number and exports worldwide, which helps when a rotation unit rebuild is being assembled from several references at once.
Gear Wheel
A gear wheel transmits drive through the rotation mechanism, converting motor output into the controlled turning force the drill string needs. Tooth condition determines whether that transfer stays smooth or begins to shock-load the components on either side of it. Damage rarely stays local — a failing gear takes its neighbours with it. Gear wheels are usually replaced as part of a rotation unit overhaul rather than singly, and it is worth quoting the mating components at the same time so the unit goes back together with matched wear. Waiting until tooth damage is visible in service tends to convert a planned overhaul into an emergency one. Stalroc supplies this Sandvik reference against its part number with worldwide export, and can quote related rotation parts together so the rebuild arrives as one consignment.
Chuck
The chuck grips the shank adapter and holds it aligned while percussion energy passes through it into the drill string. Every blow works against this component, and its wear pattern directly influences how much of the drill's energy actually reaches the rock. A worn chuck wastes energy as heat and vibration instead of penetration. Because the chuck sits in the load path, its condition affects neighbouring parts: shank adapters and bushings wear faster once the grip loses accuracy, so a single worn item quietly raises the cost of the next service. Planning replacement across that group rather than one part at a time generally gives better value. Stalroc quotes this Sandvik part by number and ships to mining, tunnelling and quarrying operations worldwide.
Rotation Motor
The rotation motor turns the drill string while percussion does the breaking, and the interaction between the two determines how cleanly a hole advances. Rotation that falls out of balance with the impact rate leaves the bit grinding rather than cutting, which shows up as slow progress and accelerated wear on the bit and shank. A rotation motor is a substantial assembly rather than a routine consumable, so lead time deserves attention in planning. Confirming the part number against the machine's parts manual before ordering avoids the most expensive mistake in this category. Stalroc sources OEM and aftermarket options for this Sandvik reference and quotes both where available, so the cost and delivery trade-off is visible before committing.
Bushing
Sliding and rotating loads inside a rock drill are carried by bushings, which take wear onto a replaceable component instead of the surrounding castings. That is their purpose: they are meant to be consumed. Left in service past their limit, the resulting clearance transfers load to parts that cost considerably more and take far longer to obtain, turning a modest spare into a major repair. Maintenance teams normally track bushing condition against drilling hours and replace on interval rather than on failure. Ordering by the Sandvik part number is the reliable route, since visually similar bushings differ between drill generations and a close match is not a match. Stalroc handles quotations by reference and exports worldwide, which suits operations that keep a small buffer stock on site.
Seal Housing
A seal housing locates and supports the sealing elements that keep hydraulic fluid where it belongs and drilling debris out. Its bore condition matters as much as the seals it carries: once the housing itself wears, new seals no longer sit true and leakage returns within a fraction of the expected interval. Replacing seals repeatedly on a worn housing is one of the more common false economies in drill maintenance. For procurement, the practical step is to check the housing whenever a seal kit is fitted and quote both together if there is any doubt. Stalroc supplies this Sandvik part against its manufacturer number and cross-checks availability before confirming, which keeps the paperwork simple when the order forms part of a larger rebuild.
Accumulator
An accumulator smooths the pressure fluctuations that hydraulic percussion generates, storing energy on one stroke and releasing it on the next. Without that damping, pressure spikes travel back through the hoses and pump, shortening the life of every component in the circuit. The charge condition changes gradually over service hours, so this is a part that degrades quietly rather than failing outright. Crews usually notice a tired accumulator as reduced penetration rate or rougher running before any warning appears. Because the symptoms overlap with several other faults, replacement is often decided during a scheduled service rather than at breakdown. Stalroc quotes this Sandvik reference by part number and ships worldwide, so it can be staged ahead of a planned shutdown instead of ordered under pressure.
Shank Bushing
Percussion energy enters the drill string through the shank, and this bushing supports and guides it while that happens. Every blow the machine delivers passes through the area, making it one of the most heavily loaded positions in the drill and one where condition translates directly into how much energy reaches the rock. Wear does not stay local: the movement a worn shank bushing allows accelerates damage to the shank adapter and chuck, converting one modest replacement into several. Tracking it against drilling hours is the standard practice. Renewing it with the components it supports keeps the front end working to matched tolerances. Stalroc quotes this Sandvik part by number and exports worldwide to drilling contractors.
Distributor
A distributor routes hydraulic flow to the points that need it, dividing supply between functions according to the circuit's design. Its condition determines whether that division stays correct: internal wear lets flow reach places it should not, and the resulting behaviour is easy to misread as a fault in whichever function seems weakest. Contamination causes most of that wear, which puts fluid cleanliness ahead of running hours as the useful predictor of service life. Diagnosing the distributor before replacing larger components can save a substantial order and a good deal of stripping. Improving filtration at the same time is what keeps the replacement from following the original. Stalroc prices this Sandvik reference from its part number and exports worldwide.
Front Bushing
The front bushing supports and guides at the working end of the drill, where percussion energy leaves the machine and enters the drill string. Position and alignment are its contribution, and both degrade gradually rather than failing outright, which is why wear here is measured against drilling hours rather than waiting for a symptom. Movement permitted by a worn front bushing accelerates damage to the shank and chuck around it, so replacement is normally planned across that group rather than one item at a time. Because the front end wears as a group, quoting those references together generally matches what the drill will need.
