Product Description
Product Overview

Fan pump / auxiliary cooling piston pump designed for Hitachi excavators ZAX870-5G, ZAX870-5B, and ZX670LC-5G. This pump supports the auxiliary cooling circuit, ensuring stable hydraulic fan operation and reliable thermal management under demanding working conditions.

Part numbers: YA00011362  |  4700708  |  9313598

Common Failures
  • Fan stops running: Solenoid failure, worn valve plate, piston seizure.
  • Overheating: Excessive internal leakage, swash plate wear, insufficient displacement.
  • Abnormal noise & vibration: Damaged bearing, spline wear, air ingestion.
  • Oil leakage: Worn oil seal, housing crack, seal failure.
Purchase Tips
  • Distinguish this fan pump from the main hydraulic pump YB60000246.
  • Verify solenoid connector, mounting flange, and port size before ordering.
  • Choose a new pump for heavy mining applications; remanufactured units are suitable for temporary use.
  • Flush the hydraulic circuit and replace the filter before installation.
