Dynapac CC900G Plus Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CC900G roller that spends its life on small paving jobs, driveways, and tight patch work, this schematic set is what I grab when the machine suddenly won’t move, vibrate, or charge and simple checks don’t show the cause. These full electrical and hydraulic diagrams let you trace how power and oil are supposed to flow through the roller, so you can logically narrow down a fault instead of guessing. For example, if the vibration won’t engage, I’ll use this to follow the control circuit and hydraulic signal from the switch all the way to the valve and motor.

Applications & Use Cases

• Trace electrical faults when a function is dead, intermittent, or blowing fuses.
• Isolate hydraulic issues like weak drive, slow vibration, or cylinders not responding.
• Verify correct routing of hoses and harnesses after component replacement.
• Cross-check wiring before splicing, adding lights, or replacing switches and sensors.
• Support parts identification by matching components on the machine to their place in the system.

FAQ

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

A: Yes, it’s practical to zoom into the diagrams on a tablet/phone, which helps when you’re tracing a single wire or hose on-site.

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

A: Many techs keep it digital but print the key pages they use most, then laminate or sleeve them for use around oil and dirt.

Safety Note

Always lock out the machine, relieve hydraulic pressure, and disconnect battery power before using these diagrams to work on live circuits or lines.
