Full Technical Description
550 519 78 DISTRIBUTOR, AIR Functioning as the heart of the drifter's pneumatic circuit, the air distributor directs the flow of high-pressure air to move the piston back and forth. Its internal passages and sealing surfaces are designed to precisely time the air supply for each stroke. This correct timing is what generates the powerful and rapid hammering action needed to fracture rock effectively.
A worn or damaged air distributor directly impacts drilling speed and overall reliability. If its sealing surfaces are scored or cracked, internal air leaks will occur, robbing the piston of its impact force. This results in a weak or erratic hammer blow, slowing down the entire drilling cycle and increasing air consumption for the same amount of work.
During a routine drifter overhaul, inspect the air distributor for any signs of scoring, pitting, or cracks on its flat surfaces. If the drifter feels sluggish or sounds weak during operation, this component is a likely cause. Replacing it is key to restoring the drifter's original impact power.
