Bobcat BL570 Backhoe Loader Service Manual (SN 570611001-570699999)

The BL570 backhoe loader is a yard and jobsite workhorse, loading trucks, trenching, and doing utility work all week long. The people who reach for this service manual are the ones actually turning wrenches when the machine stops earning money. They want factory repair steps, specs, and test procedures so they can fix it once and move on to the next ticket. If your BL570 is in the serial range listed and you're doing real repairs, this is the book you want.

What this manual helps you do

  • Trace and diagnose hydraulic problems in the loader and backhoe circuits before you start throwing parts at it
  • Check and verify hydrostatic and hydraulic pressures with the right test ports and sequences
  • Follow step-by-step teardown and reassembly on major components like cylinders, axles, and the loader/backhoe structures
  • Diagnose electrical issues using proper wiring diagrams, connector IDs, and test points
  • Replace and adjust wear items, linkages, and controls to factory procedure instead of guessing

Who this is for

This is for a shop mechanic, field tech, rental yard, or owner-operator who wants to do full repairs on a BL570 in the 570611001-570699999 serial range. If you only need basic operation or daily checks, you want the operator's handbook instead, not this service manual.

FAQ

Q: Is it a searchable PDF and can I read the wiring diagrams clearly?

A: Yes, it's typically a searchable PDF, and the wiring diagrams are laid out for on-screen zooming or printing shop copies.

Q: How do I know if it covers my exact BL570?

A: If your serial number falls between 570611001 and 570699999, this is the correct manual family for your machine.

Q: Is this the right document if I'm planning a full hydraulic or engine repair?

A: Yes, this is the workshop-level service manual that you'd use for major repairs and diagnostics, not just routine greasing and checks.

Bottom line: If you own or maintain a BL570 in that serial range and you actually repair it in-house, this is the right manual. If you just want operating tips, skip it.
