Montabert Spare Parts
Compatible rock drill components for Montabert — 8 parts listed
Montabert spare parts are supplied by Stalroc Industrial for professional drilling systems, with dependable compatibility, technical support and worldwide delivery.
Ring
The ring, part 862 202 414, seats into a machined groove inside a Montabert breaker or drill to seal or retain against internal pressure, and its cross-section is matched precisely enough to that groove that a visually close substitute rarely holds the same fit. Once it loses its original profile through wear, the pressure or retention it was providing degrades before the ring itself looks obviously worn. Because the wear is dimensional rather than visible, checking against the manufacturer reference before ordering is more reliable than judging a ring by eye.

Stop Piston
The stop piston, part 866 116 39, arrests the working piston's travel at the end of its stroke in a Montabert breaker, absorbing the impact of that arrest on every cycle rather than transmitting it onward the way the main piston does. Because it takes that shock directly and repeatedly, it wears from a different mechanism than the piston it stops, and the two are not a reliable guide to each other's condition. A stop piston that has lost material at its stopping face lets the main piston travel slightly further than designed, which shows up as harsher operation before it shows up as a measurable fault.

Driver
The driver, part 866 059 20, transmits rotational drive inside a Montabert breaker or drill, sitting in a chain where backlash at one joint adds to the next rather than staying contained. A driver with worn splines does not slip cleanly; it hammers on every reversal instead, and that hammering is what damages the components either side of it rather than the driver alone. Because it works as part of a chain, it is usually renewed alongside the components it drives during an overhaul rather than replaced on its own.

Front
The front head, part 863 533 56, forms the working end of a Montabert breaker, carrying the components that guide and retain the tool while impact energy passes through them on every blow. It is where the machine meets its consumable, and the accuracy it holds determines how much of that energy actually reaches the tool rather than being lost in the front end. Because this end takes the abrasion and shock of direct ground contact, it is normally assessed alongside the bushings and retaining pin it carries rather than inspected on its own.

Guide
The guide, part 863 450 22, keeps the piston travelling true through its stroke in a Montabert breaker, holding alignment against the side loads that percussion inevitably produces. A guide that has worn lets the piston work slightly off axis, and the consequences of that show up downstream as uneven wear on the tool and bushings rather than as anything obvious at the guide itself. Because several other faults produce similar symptoms, guides are normally checked and renewed during scheduled overhaul rather than diagnosed alone from falling performance.

Cover
The cover, part 863 247 38, closes an internal chamber on a Montabert breaker, retaining pressure while keeping dust and moisture away from the components sealed beneath it. Being 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 what it protects more directly than any other entry point in the assembly. Checking the cover's sealing face whenever the chamber beneath it is opened costs little against the risk of contaminating freshly serviced components through a cover nobody inspected.

Cylinder
The cylinder, part 863 236 72, is the machined housing the piston strokes inside on a Montabert breaker, carrying both the bore the piston seals against and the porting that drives the percussion cycle. Scoring or wear in that bore is rarely caused by the cylinder itself; it is usually the result of contamination or a worn piston running against it, which is why the piston and its seals are worth checking whenever a cylinder is condemned. Because the bore is a precision surface rather than a structural wall, damage to it is a replacement decision rather than one a site can machine its way out of.

Quick Injection Nozzle
A quick injection nozzle delivers lubricant or fluid to a specific point in a controlled quantity, and the precision of that delivery is what makes the arrangement work. Blocked or worn nozzles under-deliver quietly: the system appears to be operating while the component it serves is not receiving what it needs. The consequences show up as wear at the lubricated point rather than at the nozzle, which is why lubrication faults are sometimes diagnosed as bearing problems. Checking delivery during service is quicker than tracing the damage afterwards. Nozzles are inexpensive to hold and easy to replace on schedule, which suits them to on-site stock.
