Dynapac CA3500PD HC Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CA3500PD working in tough soil compaction on roads or pads, this schematic set is what I’d pull out when an electrical or hydraulic issue isn’t obvious from a quick visual check. It lets you follow how power and oil move through the machine so you can trace a fault instead of just swapping parts. For example, if the vibration won’t engage or the drum won’t drive correctly, these diagrams help you track the signal from the control to the valve or component and verify where it’s getting lost.

Applications & Use Cases

• Trace hydraulic circuits from pump to valve to actuator to isolate a weak or dead function.
• Follow electrical feeds and grounds to track down blown fuses, bad relays, or broken wires.
• Verify correct routing when replacing hoses or harness sections so everything goes back as designed.
• Cross-check components on the machine against the schematic to confirm you’re testing the right connector or port.
• Support remote troubleshooting by having tech and operator refer to the same circuit paths.

FAQ

Q: Can I use this on a tablet in the field?

A: Yes, it’s well-suited to digital use; you can zoom in on specific circuits while you’re at the machine.

Q: Is it worth printing parts of it?

A: Many techs print the key pages they use most, laminate them, and keep them in the service truck for quick reference.

Safety Note

Always de-energize and depressurize systems before using these diagrams to open, disconnect, or test any component.
