Dynapac CA250 Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a Dynapac CA250, you’re usually compacting subgrade, base, or asphalt on busy jobsites, often in dust, vibration, and tight time windows. This full electrical and hydraulic schematic is what I’d pull out when I need to trace how power and oil actually move through the roller. If, for example, the drum won’t vibrate but the engine runs fine, this is the map I’d use to follow the circuit from the control to the valve and right down to the component, instead of guessing and swapping parts.

Applications & Use Cases

• Trace electrical faults when a function is dead or intermittent, by following wiring from switches to relays, fuses, and actuators.
• Isolate hydraulic issues like weak travel or no vibration by tracking oil paths between pumps, valves, and motors.
• Verify correct routing after replacing harness sections or hoses, so everything is reconnected logically.
• Support parts identification by narrowing down which component in a chain is likely at fault before ordering.
• Plan tests and measurements at the right points instead of probing randomly in the machine.

FAQ

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

A: Yes, it’s practical to zoom in on symbols and circuits on a tablet; just keep the screen clean and protected from dust and impacts.

Q: Is it worth printing the whole thing?

A: I’d print key pages I use often, laminate them, and keep them in the service truck, then keep the full file digital for detailed zooming.

Safety Note

Always lock out, tag out, and relieve hydraulic pressure before probing circuits or disconnecting any lines.
