The correct installation method of Volvo EC500 Electric excavator parts
The following are the correct installation methods and key steps for Volvo EC500 Electric excavator parts:
⚙️ core installation process
Pre-installation preparation
Thoroughly clean the installation area : Use scrubbing or immersion to remove oil stains and impurities to prevent foreign objects from entering precision components (such as hydraulic systems) .
Verify the compatibility of accessories : The dedicated accessories for the electric version (such as low-noise hydraulic pumps and lithium battery heat sinks) are not compatible with the traditional diesel models. The model needs to be checked.
Power system accessories installation
Lithium battery thermal management component : When installing the temperature sensor, the interface must be sealed with a protection level of IP67, and it should be connected to the battery management computer board wiring harness .
High-voltage relay (model 20797920) : after power-off operation, it should be fixed on the shockproof bracket. After wiring, the insulation resistance should be tested with a megohmmeter .
Installation of mechanical structural components
Track idler wheel replacement :
Release the pressure of the track tensioning cylinder to lift the fuselage and keep the tracks suspended .
When disassembling the old idler wheels, use long bolts to assist in positioning and crowbars to ensure stable load-bearing (avoiding the risk of manual handling) .
The screws of the new idler wheel are coated with copper powder for rust prevention . After pre-tightening with an pneumatic wrench, they are weighed using a torque tool according to the standard value (refer to the maintenance manual).
Reinforced forearm cylinder (140mm bore) :
The chrome plating layer of the piston rod should be protected from scratches. After installation, the hydraulic system needs to be operated in a cycle to expel air .
Filtration system installation
B series pilot filter (model 0332) :
After removing the old filter element, clean the oil outlet. Apply engine oil to the sealing ring of the new filter element to enhance the sealing .
When installed vertically, it should be filled with hydraulic oil to avoid insufficient lubrication at the moment of startup.
⚠️ key points to note
Safe operation :
Before replacing high-voltage components (such as relays), cut off the power supply and verify that there is no residual voltage .
Wear goggles when operating the hydraulic system to prevent high-pressure oil from splashing .
Quality control :
After the electric special counterweight block (10,300kg) is installed, the tail turning radius (3,880mm) needs to be rechecked to ensure the center of gravity is balanced .
Maintenance and optimization :
By taking advantage of the low-position layout of the electric model (the hydraulic pump and the electrical control box are close to the ground), the maintenance flow line is simplified .
Note: Unauthorized modification of the original factory configuration (such as track width, counterweight) may affect the safety threshold and energy efficiency (the energy cost of the electric version is 50% lower than that of the diesel engine) .
