Dynapac CA3500D Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CA3500D roller that spends its life compacting base and asphalt in dust, mud, and heat, this schematic set is what I grab when something electrical or hydraulic doesn’t behave the way it should. These diagrams let you trace how power and oil are supposed to move through the machine so you can isolate where they actually stop. For example, if the vibration won’t engage or drops out under load, I use this to follow the control signal and hydraulic path step by step, instead of just throwing parts at it.

Applications & Use Cases

• Trace electrical faults from the battery and key switch through relays, fuses, and connectors to a dead function.
• Isolate hydraulic issues in the drive or vibration circuits by following hose routing and valve relationships.
• Verify wiring during component replacement, so new sensors, solenoids, or switches are correctly connected.
• Plan modifications or add-ons (like work lights or telematics) while avoiding critical factory circuits.
• Support remote troubleshooting, talking a less-experienced tech through checks using the same diagrams.

FAQ

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

A: Yes, it’s practical on a tablet; you can zoom in on symbols and follow lines without carrying multiple paper sheets.

Q: Should I still print parts of it?

A: Many techs print key pages and mark them up during diagnostics, then keep the full file digital for reference.

Safety Note

Always lock out, tag out, and relieve hydraulic pressure before acting on anything you’ve traced in these diagrams.
