Bobcat BL470 Backhoe Loader Service Manual (SN 570511001-570599999)

The BL470 is a full-size backhoe loader, the kind you're trenching with out front and loading trucks with out back. When it's down, you're losing money fast, so the service manual is what you reach for when you're chasing hydraulic issues, electrical gremlins, or doing real teardown work. Around my shop, this is the book that comes out when I've got the hood up, hoses off, and I need specs and step-by-step, not safety tips.

What this manual helps you do

  • Diagnose hydraulic problems in the loader and backhoe circuits, then check pressures and isolate bad valves or cylinders
  • Trace and repair electrical and starting/charging issues using wiring diagrams and test procedures
  • Follow engine removal, disassembly, and reassembly steps for overhauls or major gasket and seal work
  • Rebuild or replace driveline and brake components, then set clearances and verify adjustments
  • Troubleshoot steering and frame components, replace pins and bushings, and torque structural hardware correctly

Who this is for

This is for someone working on a Bobcat BL470 backhoe loader with serial number between 570511001 and 570599999 who wants to do real repair work, not just daily checks. Small contractors, field techs, shop mechanics, and owner-operators will get their money's worth. If you only need operating instructions or basic maintenance intervals, you want the operator's handbook instead.

FAQ

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

A: Yes, these manuals are normally searchable PDFs and the wiring diagrams are clear enough to zoom in and follow circuits on a laptop or tablet.

Q: Will this cover my exact BL470 machine?

A: If your serial number falls in the 570511001-570599999 range, this is the right manual. If it doesn't, you should look for the manual that matches your serial range.

Q: Is this the right document for general use and light maintenance?

A: It will work, but it's overkill if you just want fluid types and basic checks. This is meant for diagnostics and repair work.

Bottom line: If your BL470 falls in that serial range and you're turning wrenches on it yourself, this is the right manual. If the serial doesn't match, don't buy this one.
