Case 340 True-Tandem Disk Harrow Service Parts Catalogue

Case 340 True-Tandem Disk Harrow Service Parts Catalogue

Out in tilled fields and heavy residue, the Case 340 True-Tandem disk harrow is working hard, so wear parts and hardware get punished fast. This Service Parts Catalogue is what I’d pull when I need to pinpoint the exact blades, bearings, scrapers, and hydraulic pieces that belong on your machine. If, for example, a transport cylinder starts leaking or a gang bearing fails, I use this book to trace the whole assembly, confirm every seal and fastener, and order the right revision the first time.

Applications & Use Cases

• Confirm correct part numbers before ordering when there are multiple width or configuration variants.
• Study exploded views to see how gangs, scrapers, and brackets stack together and which spacers or bushings are easy to miss.
• Cross-check sub-assemblies (like transport hydraulics) so new cylinders, hoses, and fittings all match each other.
• Verify small hardware—locknuts, shims, wear washers—so you don’t reuse questionable pieces during rebuilds.
• Compare old vs. updated parts to see which superseded components will still fit your particular 340 setup.

FAQ

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

A: Yes, it’s practical to keep it digital; you can zoom in on diagrams and search part descriptions right at the machine.

Q: Is it worth printing sections of this manual?

A: Many techs print the pages for the assemblies they’re rebuilding, then mark notes and part quantities directly on the sheet.

Safety Note

Always isolate and support the disk harrow safely before inspecting or matching parts from this catalogue.
