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

These Puma 220 Tier 4B tractors usually live in fields, feedlots, and on the road pulling heavy gear, running long hours in dust, mud, and cold starts. This service manual’s about helping you trace a fault properly instead of just throwing parts at it. Say the tractor loses power under load: you’d follow the book to check fuel supply, verify boost, test sensors, and isolate whether it’s fuel, air, or electronic before you order a single component.

Applications & Use Cases

• Trace hydraulic problems by following the test sequence, so you can tell if it’s a weak pump, a leaking spool, or a mis-set relief valve.
• Check and verify transmission issues—harsh shifts, no drive, codes—using step-by-step pressure and electrical checks.
• Inspect and route wiring correctly when chasing intermittent faults, so you don’t miss a rubbed-through harness under the cab.
• Bleed and align steering and brake systems the way the factory expects, which usually saves you from repeat comebacks.
• Test sensors and valves on the Tier 4B emissions system to see what’s actually bad before you touch the aftertreatment hardware.

FAQ

Q: Is this something I can search on a laptop, or is it just scanned pictures?

A: It’s typically a searchable PDF, so you can jump to sections and keywords instead of flipping pages.

Q: Can I print pages and take them out to the tractor?

A: Yes, most folks print the procedures or diagrams they need, stick them in a sleeve, and keep the full file on a computer or tablet in the shop.

Safety Note

Always depressurize hydraulic and fuel systems and verify everything’s safely supported before you crack a line or pull a component.
