Case Puma 220 CVX Tier 4B Final Tractor Service Manual (51666845) (March 2021)

Out in the field, this Puma 220 CVX is usually pulling heavy tillage, running big drills, or on a wagon train, working long days in dust, mud, and cold starts. This service manual helps you trace faults step by step so you don’t just throw sensors and valves at it. Say the tractor drops power under load—this book walks you through how to check fuel supply, verify boost, test sensors, and isolate whether it’s fuel, air, or transmission protection cutting in.

Applications & Use Cases

• Track down hydraulic issues by tracing circuits, checking pressures with the proper ports, and isolating a bad remote or hitch valve before you touch the pump.
• Chase electrical gremlins: follow wiring routes, inspect connectors, test with a meter, and verify a component’s dead before you order it.
• Sort transmission or CVX complaints by running the guided tests, checking calibration status, and aligning what the customer feels with actual fault codes.
• Bleed and service fuel and DEF systems the way the factory expects, so you don’t introduce air or contaminate the aftertreatment.
• Plan bigger jobs—clutch, front axle, cab removal—by seeing how to support, route hoses, and re‑align everything on the way back together.

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 straight to systems, fault codes, or test procedures.

Q: Can I print just the sections I need for the shop?

A: You usually can; most folks print the relevant procedures so they can get them greasy without risking the whole file.

Safety Note

Always support and chock the tractor properly before you crawl under it or crack any high‑pressure lines.
