LIEBHERR HYDRAULIC PRESSURE GOVERNOR REPAIR KIT

Ask about product

This repair kit contains essential seals, O-rings, back-up rings, and springs required to overhaul the hydraulic pressure governor on Liebherr excavators. It restores precise pressure control and flow regulation for the main axial piston pump, preventing internal leakage and overheating. Scheduled replacement is significantly more cost-effective than replacing the entire regulator or repairing a damaged main pump.
