Case Precision Disk 500 Disk Drill Service Manual (90350607 Replaces 90350607) (July 2021)

Out in the field, this Case Precision Disk 500 drill is usually running long days in dust, fertilizer, and mud, folding and unfolding, turning tight, and riding rough ground. This service manual walks you through how to trace, check, and verify problems before you start throwing parts at it. Say your wings won’t lift right: instead of guessing at a cylinder, you’ll follow a sequence—inspect hoses, test hydraulic flow, isolate the valve, then confirm what’s actually failed.

Applications & Use Cases

• Track down uneven seed depth by inspecting openers, checking down-pressure circuits, and aligning the toolbar step by step.
• Chase a hydraulic issue by routing through the schematic, testing sections one at a time, and isolating a sticky valve instead of changing every hose.
• Verify frame and hitch problems by checking pivot points, measuring play where it matters, and deciding if it needs shims or full rebuild.
• Bleed and test hydraulic components after repairs so you don’t trap air and end up redoing the job in the middle of seeding.
• Plan off-season maintenance: inspect wear parts, set a logical order for repairs, and avoid tearing the same section apart twice.

FAQ

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

A: Yes, it’s typically a searchable PDF, so you can 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 hydraulic and adjustment procedures so they don’t get their device wrecked in the dust and oil.

Safety Note

Always depressurize and lock out the hydraulic system before you crack any lines or start loosening components.
