4120008560 Pilot Gear Pump for SDLG E6210 and E6210F Excavators
The SDLG / Shandong Lingong 4120008560 Gear Pump (commonly designated by the model manufacturer code HPT3-100) is a high-pressure, fixed-displacement hydraulic gear pump. It handles pilot control fluid delivery, steering assistance, or auxiliary work functions across Chinese-manufactured heavy construction equipment.
Machine Compatibility
· SDLG Series Equipment: Integrated heavily into SDLG E6210, E6210F, and E6250F crawler excavators, as well as select multi-ton wheel loader groups.
· Cross-OEM Applications: Due to standard multi-bolt pattern standardization, the pump interchanges into alternative model networks including Sany SY215, XCMG XE215, and LiuGong CLG920.

Q&A Section
Q1: What are the signs of a failing 4120008560 pilot pump?
A: The most common sign is "heavy" or non-responsive joysticks. If the gear pump fails, the pilot system cannot shift the spools in the main control valve. You may also notice a high-pitched whining noise coming from the pump area.
Q2: Can I use this pump if my machine is branded as Volvo?
A: SDLG and Volvo share many engineering platforms. If your Volvo excavator (such as an EC210 series) cross-references to the 4120008560 part number, it is likely compatible. However, always check the shaft spline count and port sizes before installation.
Q3: Should I replace the pilot filter at the same time?
A: Yes. If a gear pump fails, it often releases small metal shavings into the pilot circuit. You must replace the pilot oil filter and clean the suction strainer to prevent these particles from damaging your joysticks or the main control valve.
