Bobcat BL570 Backhoe Loader Service Manual (SN 572611001-572699999)

The BL570 is a full-size backhoe loader, so think trenching utilities, loading trucks, and site cleanup around tighter jobsites where a big wheel loader is overkill. The service manual is what you grab when the machine is down and you need real specs and step-by-step repair info, not just where the buttons are. Around my shop, I reach for this type of book when I'm chasing hydraulic issues, doing engine work, or sorting out weird electrical faults. If you're trying to keep downtime and dealer bills under control, this is the kind of manual you want.

What this manual helps you do

  • Diagnose hydraulic problems, check pressures, and trace leaks on the loader and backhoe circuits
  • Follow teardown and reassembly steps for cylinders, pumps, valves, and driveline components
  • Troubleshoot electrical issues using wiring diagrams, connector callouts, and test procedures
  • Set and verify adjustments on linkages, brakes, steering, and loader/backhoe controls
  • Replace major components like engines, axles, and drive parts with the right sequences and specs

Who this is for

This is aimed at small contractors, shop mechanics, field techs, rental fleets, and owner-operators who actually turn wrenches on a BL570. If you just need operating tips or safety info, you want the operator's handbook, not this service manual.

FAQ

Q: Is this a searchable PDF and are the wiring diagrams readable?

A: Yes, these manuals are usually searchable PDFs, and the wiring diagrams are designed so you can zoom in and read pin numbers and wire colors.

Q: How do I know if it covers my exact machine?

A: If your BL570 serial number falls between 572611001 and 572699999, this is the correct manual. If it's outside that range, it may not match.

Q: Is this the right document if I'm planning major repairs?

A: Yes, this is the workshop-level service manual, which is what you want for real diagnostics, teardown, and rebuild work.

Bottom line: If you own a BL570 in that serial range and plan to wrench on it yourself, this is the right manual. If your serial is different, don't buy this one.
