Dynapac CA300 Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CA300 compactor that lives in dust, vibration, and long days on road base or landfill cover, this schematic set is what I’d grab when an electrical or hydraulic function isn’t behaving. It lets you trace how power and oil are supposed to move through the machine, so you can isolate a fault instead of guessing. For example, if the vibration drum won’t engage, these diagrams help you follow the control circuit and hydraulic signal path step by step to see whether you’ve got an electrical command issue or a hydraulic flow problem.

Applications & Use Cases

• Track down dead circuits by following wiring paths from battery to switch to solenoid and verifying where voltage is lost.
• Trace hydraulic functions to see which valve, line, or control signal is in the chain when a cylinder or motor won’t move correctly.
• Confirm correct routing after replacing hoses or harness sections so everything is reconnected to the right ports and plugs.
• Plan diagnostic tests at the right connectors and test ports instead of opening up half the machine.
• Support parts identification by matching components on the machine to their symbols in the system layout.

FAQ

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

A: Yes, it’s practical to zoom in on circuits on a tablet or laptop, which makes following individual wires and lines much easier on-site.

Q: Is it worth printing, or should I keep it digital only?

A: Many techs keep a digital copy for zooming, then print the key pages they use often and laminate them for use around oil and dirt.

Safety Note

Always de-energize and depressurize electrical and hydraulic systems before using these diagrams to test or disconnect anything.
