Full Technical Description

1000HRS KIT 5728 6026 81 Performing a scheduled 1000-hour service is fundamental to maintaining the health of a hydraulic drifter. This service kit provides all the necessary components to overhaul the core internal mechanisms, including the impact piston, rotation motor, and flushing seals. By replacing these critical wear parts together, you restore the tight tolerances required for efficient energy transfer from the hydraulic fluid to the rock.

A drifter rebuilt with this complete kit will operate closer to its original specifications, delivering consistent impact power and torque. This directly translates to better penetration rates and straighter holes. Neglecting this service can lead to a gradual loss of performance, internal hydraulic leaks that generate heat, and eventually a major component failure. It’s a key step in ensuring the reliability of the entire drilling rig.

The need for this overhaul is typically indicated by the machine’s hour meter. However, if you notice significant oil leaks from the drifter front head or a noticeable drop in drilling speed, the service may be overdue. When installing the kit, always replace all included components, as reusing an old seal can compromise the entire rebuild.
