Kawasaki HPV102 Hydraulic Main Pump Seal Kit

This seal kit is engineered for the Kawasaki HPV102 series variable displacement axial piston hydraulic main pump, widely deployed on Hitachi 20-27 tonne class excavators. The kit contains a complete set of sealing elements required for pump disassembly and overhaul, including high-pressure shaft seals (TCN type, 55x78x12), assorted O-rings in NBR and FKM materials, backup rings, and the main pump cover gasket (Hitachi 8058352). The HPV102 pump (displacement 102 cc/rev, max pressure 35 MPa) serves as the main hydraulic power source for Hitachi EX200-5, EX200-6, EX220-5, ZX200, ZX200-3, ZX200-3G, ZX210, ZX230, ZX240, and ZX270 models equipped with Isuzu direct injection engines. This kit restores sealing integrity to prevent internal and external leakage, ensuring stable hydraulic pressure and flow performance.
