Case TR340 Track Loader Service Parts Catalogue (550711123PC)

Case TR340 Track Loader Service Parts Catalogue (550711123PC) (September 2025)

A TR340 usually lives in the rough stuff—muddy jobsites, demo rubble, tight lots where you’re hopping curbs and dragging pallets. This Service Parts Catalogue doesn’t teach you how to wrench; it helps you plan the job so you’ve got every seal, pin, and bushing on the bench before you crack anything loose. Say you’re chasing a slow lift-arm leak: you can trace the cylinder in the exploded view, match the rod seal and wiper by number, and order the right kit once, not three times.

Applications & Use Cases

• Pre-planning big jobs: Before you pull a final drive, inspect the diagram, list every O-ring, snap ring, and gasket, and have them on the shelf so the machine’s not dead in the yard all week.
• Matching parts during teardown: As you strip a boom or quick coupler, you can lay parts out and verify each one against the exploded view so nothing “extra” is left on the cart.
• Avoiding wrong orders: When two bushings look identical, you’ll isolate them by suffix and position on the diagram instead of guessing and eating return shipping.
• Routing hoses and lines: You can check how hoses are supposed to route and clamp, then test movement so nothing rubs through after you button it up.
• Stocking the shop: Use it to build a small bin of wear items you know you’ll burn through—pins, filters, common seals—so you won’t wait on the truck.

FAQ

Q: Is this a searchable PDF, or am I flipping pages like a paper book?

A: It’s typically a PDF you can search by part number or description, then jump right to the section you need.

Q: Can I print just a few diagrams to take out to the machine?

A: Yes, you can usually print specific pages, stick them in a sleeve, and keep greasy hands off your laptop.

Safety Note

Before you trace any part on the machine, drop attachments, relieve pressure, and lock out the loader so it can’t move while you’re inspecting it.
