Information About 4460890
The 4460890 is a comprehensive hydraulic rebuild kit that includes a precision-machined cylinder block and a fully matched set of high-strength pistons. It is designed specifically for the widely used Sauer Sundstrand M46 series of closed-circuit hydrostatic pumps and motors. Constructed with wear-resistant metallic alloys, it effectively withstands the continuous friction and thermal stress generated by heavy earthmoving and agricultural machinery. By restoring the internal volumetric efficiency of the hydraulic unit, it eliminates fluid bypass and returns the equipment to its peak operational performance.
Key Features:
-
OEM Precision: Manufactured to exact factory specifications to ensure perfect mechanical alignment within M46 housings.
-
Complete Kit Assembly: Includes both the primary cylinder block and matched pistons for a comprehensive internal rebuild.
-
High-Pressure Durability: Constructed from premium wear-resistant alloys to endure extreme closed-circuit hydrostatic pressures.
-
Volumetric Restoration: Eliminates internal fluid leakage to restore the full hydraulic power output of the pump or motor.
-
Heavy-Duty Application: Designed specifically for the rigorous demands of agricultural, construction, and industrial machinery.
-
Friction Reduction: Utilizes polished piston surfaces and precise block tolerances to minimize internal mechanical wear.
The 4460890 delivers the reliability and precision required for advanced hydrostatic pump and motor restoration.
