Case Precision Air 3445 Air Cart Service Manual (92080200) (July 2023)

These air carts live in dust, fertilizer, and mud, usually hooked behind a big tractor all season long. This manual helps you trace air delivery issues, chase hydraulic problems, and verify brake and axle concerns before you start throwing parts at it. Say your meter rollers are acting up and one tank won’t meter right—this book walks you through how to inspect the drive, check the sensors, and test the hydraulic feed so you can isolate the real fault instead of guessing.

Applications & Use Cases

• Track down uneven product distribution by following the step-by-step checks on meters, fans, and air tubes so you can isolate whether it’s mechanical, hydraulic, or just a blockage.
• Use the hydraulic troubleshooting flow to test valves, route hoses correctly, and verify pressure signals before you condemn a pump or motor.
• Inspect and align front and rear axles when you’re seeing odd tire wear or wandering, then verify bearings and linkage instead of replacing whole assemblies.
• Trace brake issues—spongy pedal, dragging wheel—by bleeding, testing, and isolating each circuit so you know exactly what’s failed.
• After an off-season rebuild, go through the adjustment procedures to check clearances and verify everything’s set up right before you hit the field.

FAQ

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

A: Yes, it’s typically a PDF, so you can search by keyword and jump straight to the system you’re working on.

Q: Can I print just a few sections to take to the field?

A: You usually can; most folks print the diagrams and procedures they use most so they don’t risk wrecking their device in the dust and fertilizer.

Safety Note

Always bleed off hydraulic and air pressure and verify everything’s blocked and supported before you crawl under or crack any lines.
