Full Technical Description

1000 HOURS P 2658 6820 92 This package provides the full set of genuine seals, o-rings, and diaphragms required for a complete 1000-hour preventive maintenance service. These components are installed inside the main body of the hydraulic drifter, renewing the critical sealing functions within the percussion mechanism, rotation motor, and accumulator circuits.

Replacing all wear parts at once is crucial for maintaining consistent drilling power and preventing unplanned breakdowns. For instance, a worn internal piston seal, which is included, will cause a loss of impact energy and a significant drop in penetration rate. A properly rebuilt drifter operates more efficiently and reduces the risk of sudden hydraulic failures during a shift.

A noticeable decrease in drilling speed, sluggish rotation, or oil leaking from the drifter’s front head are clear signs this service is needed. For a successful rebuild, perform the work in a clean environment and replace every part from the kit, as this guarantees the drifter is ready for another full service interval.
