Furukawa Spare Parts
Compatible rock drill components for Furukawa — 5 parts listed
Furukawa spare parts are supplied by Stalroc Industrial for demanding drilling applications, with reliable compatibility, technical support and worldwide delivery.
Chuck Driver
The chuck driver connects the piston's percussive energy to the tool bushing and, through it, to the chisel working the rock or concrete face. On the Furukawa HD715, part HD71502025 sits at the lower end of the housing, so every impact the breaker delivers passes through it before reaching the tool. Excessive internal clearance lets the tool wander with each blow, showing up first as uneven shank wear and later as vibration through the boom. Because the driver takes the harshest combination of impact and contamination on the machine, it is worth checking during scheduled tool changes rather than waiting for a symptom severe enough to notice during normal operation. Many workshops replace it alongside the front and rear bush as a wear group, since running one worn component against fresh neighbours usually just shortens everyone's service life.

Gear Drive
The gear drive, part HD71502007, belongs to the HD715 breaker's rotation mechanism rather than the direct percussion path, converting rotary input into controlled movement of the tool holder. Wear here tends to show up as backlash first, a small amount of play a technician can feel by hand before it becomes visible as tooth wear. Because this component supports rotation rather than the strike itself, symptoms can be subtler than a failing chuck driver: rotation feeling rougher, or the tool holder not sitting quite where expected. Catching it at the backlash stage keeps the job a straightforward parts swap; run past that point and the fault risks damaging the mating gear and housing bore as well.

Piston Bushing
The piston bushing, part HD71201528, guides the reciprocating piston inside the cylinder bore of the Furukawa HD712 breaker, keeping it centred and sealed through thousands of strikes per hour. Excess clearance lets the piston run off-axis, and the resulting internal bypass reduces blow energy even though the hydraulic circuit upstream is performing normally, a common diagnostic trap. Because the bushing sits inside the cylinder, replacing it means a proper strip-down, which makes it a component best assessed during scheduled major service rather than reactively. Most workshops use that access to check piston condition and the seal kit at the same time, since a seal that fails shortly afterward will simply recontaminate a brand new bushing.

Bush Front
The front bush, part HD71502202, sits at the lower end of the HD715 housing where it guides and supports the tool shank closest to the working face, absorbing the side loads generated whenever a tool is worked at an angle rather than straight down. Of the tool guidance group it typically wears fastest, being the most exposed to dust and debris. A worn front bush lets the tool move laterally, and that play transmits upward into the chuck driver and housing bore, both far more costly to repair than the bush itself. Most workshops replace the front and rear bush together rather than singly, since the two wear at similar rates supporting the same shank.

Seal Kit
A seal kit brings together the sealing elements an assembly needs for a rebuild, supplied as a matched set so the job can be completed without discovering a missing item partway through. Seals are consumable by design and are renewed whenever a hydraulic assembly is opened, regardless of how the removed ones look. The common error is fitting new seals into a bore or onto a rod that is already scored, which returns the leak within a fraction of the expected interval. Assessing those surfaces before the kit goes in is what makes fitting it worthwhile. Because kits are specific to the assembly and its generation, ordering against the manufacturer reference avoids a set that does not match.
