Case CX28D, CX35D Mini Excavator Service Manual (92235270) (July 2024)

These CX28D and CX35D minis usually live in tight jobsites—residential digs, utility trenches, cleanup around buildings—where you don’t have room to screw around guessing at problems. This service manual helps you trace faults step by step, so you can verify what’s actually bad before you start hanging parts. Say your boom’s drifting down overnight: with this, you’d follow the hydraulic section, isolate the circuit, test the cylinder and control valve in order, and know if it’s a seal issue or a valve leak instead of just throwing cylinders at it.

Applications & Use Cases

• Track down a no-start by following the electrical diagnostics to check power, grounds, switches, then test components in sequence.
• Chase slow or jerky hydraulics by tracing pump supply, filters, reliefs, and control valves instead of just blaming the pump.
• Verify travel issues—machine pulling to one side—by inspecting track tension, then testing motors and final drives in the order they lay out.
• Isolate weird overheating by checking coolant flow, fan drive, and hydraulic load the way they route it in the troubleshooting charts.
• Align and bleed after component swaps (cylinders, hoses, valves) so you don’t trap air or mis-route lines and create new problems.

FAQ

Q: Is this a PDF I can search on my laptop or tablet?

A: Yes, it’s typically a searchable PDF, so you can jump to sections and run keyword searches instead of flipping pages.

Q: Can I print just the pages I need for a job?

A: You usually can; most folks print the specific procedures or diagrams, stick them in a sleeve, and toss them in the truck.

Safety Note

Always relieve hydraulic and system pressure exactly as they describe before you crack any lines or pull components.
