These Case harvesters spend their lives pulling hard in dusty fields, often with long hours and short service windows. This shop manual is what I’d keep open when I’m deep into the engine work—it lays out how to tear down, inspect, and put things back so you only do the job once. If a 856 starts losing power under load and blowing smoke, I’d use this to trace the fault methodically, verify wear points, and follow the right sequence for stripping and rebuilding the engine without guessing.

Applications & Use Cases

• Plan a full engine teardown on a 706–1456 series machine so parts come off in order and go back on without missed hardware.
• Inspect and measure wear areas during an in-frame overhaul, so you know what must be replaced versus what can safely go back in.
• Trace hard-start or low-power complaints and isolate whether you’re dealing with fuel, compression, or timing issues.
• Follow a logical sequence for resealing covers and housings to prevent repeat oil leaks after reassembly.
• Verify adjustments after a top-end job so valves, linkages, and timing are aligned before you fire it back up.

FAQ

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

A: Yes, it works well digitally; you can zoom diagrams and keep your hands free while you work.

Q: Is it worth printing certain pages?

A: I’d print torque/sequence and adjustment pages, put them in plastic sleeves, and keep them right at the tractor.

Safety Note

Always lock out the machine, support components securely, and never work under any raised part without solid mechanical stands.
