What the DAMPING PISTON does
The damping system absorbs the energy that reflects back up the drill string when the bit meets a void, a fracture or a change in rock hardness. Without it that reflected shock travels into the drifter's own structure. Damping components take deliberate punishment so the housings and the feed do not.
Signs it needs replacing
- Heavy vibration transmitted into the boom and feed
- Cracking of drill rods and couplings above normal rates
- Loss of the drifter's ability to hold the drill string against the rock
- Falling penetration rate in fractured ground specifically
Before you fit it
Replace damping components as a set and check the drill string for straightness at the same time — a bent rod feeds reflected energy back continuously and will consume the new parts at the same rate.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
