Piston

Intended for equipment that operates under repeated load, vibration and contamination exposure, the Piston (OEM 2651 2431 29) supports the percussion and drifter assembly. Its role is tied to the high-cycle impact section of the drifter, where reliable fit and controlled movement influence energy transfer to the drill string.

It gives maintenance teams another sourcing path for the referenced application without compromising the need for dimensional and functional compatibility. Impact-loaded surfaces and mating dimensions require tight control because repeated shock, vibration and high contact stress can accelerate wear at the drifter interface. Application data associates this reference with VL 140; configuration and serial-number checks are recommended before purchase.

Within Delkom’s rock-drilling replacement-parts portfolio, this item is intended to support reliable maintenance and efficient global sourcing. Include Delkom reference 140 101 836 and OEM reference 2651 2431 29 in your enquiry for an accurate quotation.
