Dynapac CA702D Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CA702D, you’re usually out on big earthwork or road jobs, working in dust, vibration, and weather that’s hard on wiring and hydraulics. This schematic set is what I reach for when an electrical or hydraulic function doesn’t behave and I need to trace a circuit from the control to the component. For example, if the vibratory drum won’t engage, these diagrams let me follow the signal and oil path step by step to see if I’ve got a switch issue, a broken wire, or a valve problem instead of just throwing parts at it.

Applications & Use Cases

• Track down intermittent electrical faults by following each wire and connector logically through the machine.
• Isolate hydraulic issues by mapping which valves, lines, and actuators are tied to a specific function.
• Verify correct routing when replacing harness sections, hoses, or adding auxiliary wiring.
• Cross-check component locations and relationships before tearing into a crowded area.
• Support remote troubleshooting by having a common reference with the tech on-site or the dealer.

FAQ

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

A: Yes, it’s practical to keep it on a tablet or laptop so you can zoom in on symbols and follow circuits right at the machine.

Q: Is it worth printing parts of it?

A: Many techs print the key pages they use often and keep them in a binder or plastic sleeves in the service truck.

Safety Note

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