Product Description
The y855mk4 is a hydraulic motor that converts pressurized fluid into rotary mechanical output for aircraft actuation and drive functions. Commonly installed in power transfer units to mechanically drive hydraulic pumps between aircraft systems. The motor receives pressurized fluid input and delivers continuous rotary shaft output to connected mechanical loads.
Installation and testing must follow the aircraft maintenance manual and be verified against the Illustrated Parts Catalog. SAE ARP4940A provides aerospace application guidance, with engine-start motor requirements detailed in SAE AS714A.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
