Dynapac CC422V Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CC422V, you’re usually working on tight paving jobs, hot asphalt, and dusty sites where downtime is expensive. This schematic set is what I’d keep open when I need to trace how power and oil actually move through the machine, not just guess from experience. If, say, the vibratory drum won’t start but the engine runs fine, I’d use these diagrams to follow the electrical feed to the valve, then cross-check the hydraulic circuit to see where the signal or flow stops.

Applications & Use Cases

• Trace electrical faults from the battery to switches, relays, and actuators when a function is dead or intermittent.
• Isolate hydraulic issues by following oil paths to cylinders, motors, and valves before you start cracking lines loose.
• Verify correct routing after harness, sensor, or hose replacement so nothing gets mis-pinned or mis-plumbed.
• Plan modifications or add-ons (lights, beacons, simple accessories) without overloading the wrong circuit.
• Support parts identification by matching components in the schematic to what you see on the roller.

FAQ

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

A: Yes, it’s well-suited for zooming and panning on a tablet or laptop next to the machine.

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

A: Many techs print key pages for greasy work, but keep the full file digital for quick searching and backups.

Safety Note

Always de-energize and de-pressurize the machine before using these schematics to inspect or disconnect any component.
