How to judge the quality of Volvo L120 electric loader parts
To judge the quality of Volvo L120 electric loader parts, the following key dimensions should be comprehensively considered, taking into account the particularity of the electric system and the reliability of general parts:
I. Key points for inspection of electric-specific components
Power and battery components
Motor protective cover : Check the material hardness and the design of the heat dissipation holes. The original factory cover body needs to precisely match the 230kW heat dissipation requirements of the permanent magnet synchronous motor. Counterfeit parts are prone to overheating risk .
Battery filter : Confirm the dust resistance grade (such as IP6X) and air permeability. A poor-quality filter will reduce the heat dissipation efficiency of the 282kWh battery pack and accelerate aging .
Electrically controlled hydraulic seal
The high-pressure sealing ring needs to withstand a pressure of 35MPa in the plunger pump system. When the surface is gently scratched with a fingernail, the original factory part has no scratches and strong resilience, while the counterfeit part is prone to deformation and leakage .
II. Methods for identifying general accessories
Packaging and labeling verification
Original factory packaging : Clear color box printing, three-dimensional embossed Volvo LOGO, including unique traceability code (such as 20440388 hydraulic filter element) and anti-counterfeiting coating .
Third-party accessories : Compare the pictures on the official websites of brands such as Sandvik to confirm the alloy steel grade of the bucket teeth (such as Hardox450) and laser anti-counterfeiting .
Physical property test
Qualified standards for accessory type inspection methods
The hammering cutting edge of the bucket teeth has no cracks and only a shallow indentation remains
The inner wall roughness Ra of the pin shaft bushing is measured to be ≤1.6μm and it contains a self-lubricating coating
The O-ring should be stretched to twice its original length and then released for 30 seconds to return to its original shape
️ III. Channel risk avoidance
Priority official channels
Enter the fuselage serial number through the Volvo accessories platform to lock the exclusive electric accessory .
Check the "lifetime warranty for parts" label and enjoy the original factory quality guarantee .
Third-party procurement Alert
Reject alloy structural components (such as bucket blade plates) without hardness test reports ;
Do not mix fuel version transmission box accessories. Electric transmission box is specially designed .
Ultimate verification : Key modules (such as the electronic control unit) are connected to the Volvo VIDA diagnostic system to read real-time compatibility and energy consumption data of accessories .
