Dynapac CA250-2 Compaction Full Schematics Diagrams (Electrical and Hydraulic)

These CA250-2 rollers spend their lives on road bases and pads, vibrating hard in dust, mud, and heat, so electrical and hydraulic issues are common. This full schematics set is what I use when I need to see how power and oil actually move through the machine, not just guess at it. If, for example, the vibration won’t engage but the drum drive still works, I’ll go straight to these diagrams to trace the control signal and the hydraulic feed to the vibration circuit and isolate where it’s dropping out.

Applications & Use Cases

• Track an electrical fault from the battery, through switches and relays, to a dead light, gauge, or solenoid.
• Trace hydraulic flow paths to verify which valve, line, or actuator is affecting drive, steering, or vibration.
• Confirm correct wiring when replacing harness sections, connectors, or retrofitting components.
• Plan safe test points for pressure gauges and multimeter leads before you start probing on the machine.
• Cross-check parts calls by matching connectors, coils, and valve bodies to their locations in the system layout.

FAQ

Q: Can I zoom in on small symbols and line labels on a tablet?

A: Yes, the diagrams are well-suited to zooming so you can read pin IDs and line routes right at the machine.

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

A: Many techs do both—print key pages for the toolbox and keep the full file on a laptop or tablet for detailed tracing.

Safety Note

Always de-energize and de-pressurize the system before using these schematics to probe, disconnect, or test any circuit.
