Product Uses
Walking Drive System
Hydraulic continuously variable transmission mechanism
Small tracked combine harvester power output unit
As the core assembly, Housing is a structural component that is rarely replaced during maintenance but is crucial
Product Operate Guide
Precautions for replacement and maintenance
Housing is an irreparable part, and once cracks, deformations, or damage to the sealing surface occur, the assembly must be replaced.
When replacing, synchronous inspection is required:
Wear of distribution plate
Plunger Assembly
Slant plate wear
Bearings and oil seals
The installation must maintain cleanliness (NAS grade 8-9) to prevent particles from entering the plug holes.
Pressure and leakage tests should be conducted before starting the machine.
