Case 200 International Harvester Service Manual (IH-201)

Out in the field or around the yard, that old Case 200 is usually dragging implements, running a belt, or handling loader work in dust, mud, and cold starts. This IH-201 service manual is about walking you through how a mechanic would trace a problem, not just throw parts at it. Say the tractor won’t pull right under load—you’d follow the steps to check clutch linkage, inspect the pressure plate, verify adjustment, and only then decide if anything actually needs replacing.

Applications & Use Cases

• Track down a no-start by tracing fuel and ignition step by step, so you isolate whether it’s spark, fuel delivery, or compression before buying parts.
• Chase overheating by checking coolant flow, testing the thermostat, and inspecting the water pump instead of guessing with random flushes.
• Sort out weak brakes by verifying pedal free play, inspecting linkage and seals, and deciding if you bleed the system or rebuild components.
• Tune a rough-running engine by routing through carb adjustments, checking governor action, and confirming timing in a logical sequence.
• Diagnose poor PTO or belt pulley performance by checking engagement, alignment, and wear so you don’t tear it down twice.

FAQ

Q: Is this a scanned manual, and can I search it on my computer?

A: It’s typically a scanned PDF; you can usually search text, but some pages may be images, so plan on a mix of scrolling and keyword search.

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

A: Yeah, most folks print the systems they’re working on, stick them in plastic sleeves, and keep the original file safe on a computer or USB.

Safety Note

Always block and secure the tractor solidly before you crawl under it or start testing anything around moving driveline parts.
