Dynapac CC722C Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CC722C roller that spends its life on big paving jobs and heavy compaction work, this schematic set is what I reach for when something electrical or hydraulic doesn’t behave the way it should. It lets me trace how power and oil are supposed to move through the machine so I can decide if I’m chasing a bad switch, a broken wire, or a stuck valve. For example, if one drum stops vibrating while the rest of the machine seems fine, these diagrams help me follow the control signal and hydraulic path until I find where it drops out.

Applications & Use Cases

• Trace electrical faults from the battery and key switch through relays, fuses, and harness branches to a dead component.
• Isolate hydraulic issues by following pump-to-valve-to-motor routing when a drum or function is weak or inoperative.
• Verify correct wiring after repairs so replaced connectors, sensors, or harness sections are landed on the right circuits.
• Plan modifications or accessory installs without overloading existing circuits or disturbing critical control lines.
• Support parts identification by matching harness legs and hydraulic lines to the right components before ordering.

FAQ

Q: Can I zoom in on these diagrams on a tablet or laptop in the field?

A: Yes, you can view and zoom them digitally, which makes reading pin labels and line routes much easier on the jobsite.

Q: Is it worth printing sections of the schematics?

A: Many techs print the pages they need for a specific fault, mark them up during testing, then keep those in a job folder for future reference.

Safety Note

Always lock out the machine, relieve hydraulic pressure, and verify circuits are de-energized before probing or disconnecting anything.
