Case Harvester Collection I & T International Service Manual

These Case harvesters spend their lives in dust, crop residue, and long days in the field, so things wear, go out of adjustment, and occasionally fail right when you need them. This Case Harvester Collection I & T International Service Manual is what I’d pull out when I have to trace a problem methodically instead of guessing. If, for example, the machine won’t slow properly on a downhill run, I’d use this to walk through the brake adjustment and linkage checks in the right order, then verify the fix before sending it back to work.

Applications & Use Cases

Chasing brake issues, from weak stopping power to dragging brakes, by following a logical adjustment and inspection sequence.
Diagnosing drive and belt problems, using step‑by‑step checks to isolate a slipping or misaligned belt pulley.
Planning disassembly and reassembly, so components come off and go back on in a clean, controlled workflow without “extra” leftover parts.
Setting up adjustments after repairs, such as linkage, clearances, and travel limits, to keep the harvester tracking straight and stopping evenly.
Training newer techs, giving them a structured process to test, verify, and document what they’ve done on each job.

FAQ

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

A: Yes, it’s practical to keep a digital copy on a tablet or laptop so you can zoom diagrams and search procedures right beside the machine.

Q: Is it worth printing sections of this manual?

A: Many techs print only the pages they need for a job, put them in a plastic sleeve, and mark notes or measurements directly on them.

Safety Note

Always support the machine securely and follow lockout procedures before working under or around any moving or suspended components.
