Product Introduction:
The gear pump with part number 2256-61-05000 is a hydraulic component used in the Shantui SG27 motor grader. It is part of the machine's hydraulic system, which operates at a relief pressure of 18 MPa .
1. Installation Location
This pump is installed within the hydraulic system of the SG27 grader, typically driven by the engine through a PTO (power take-off) connection. The SG27 is powered by a Weichai WP7G270E302 engine producing 270 hp (199 kW) .
2. Function
The gear pump converts mechanical power from the engine into hydraulic flow. In the SG27, this flow powers the implement hydraulic system, which controls the moldboard (blade) and other attachments. The SG27's blade has a width of 3965 mm and a maximum cutting depth of 500 mm .
3. Maintenance and Service
As a hydraulic component, this pump requires clean hydraulic fluid for reliable operation. The SG27 has a hydraulic oil tank capacity of 110 L . The machine is designed with a centralized pressure testing system and service access (side guard with 135° opening angle) to facilitate maintenance . If the pump fails or shows wear, replacement with an identical 2256-61-05000 unit is recommended. Before removal, depressurize the hydraulic system.
4. Important Notes
Always verify the part number 2256-61-05000 matches the original component specification for the specific SG27 model. Use only clean hydraulic fluid meeting the manufacturer's specifications. This part number corresponds to the Shantui SG27 system and may not be compatible with other models.
