Bobcat B100 Backhoe Loader Service Manual (SN 572111001-572199999)

A B100 backhoe loader is the kind of machine that spends its life trenching, loading trucks, and doing utility work around jobsites and farms. When it starts creeping, blowing hoses, or losing power, this is when guys like you and me reach for the service manual. Around my shop, I pull a manual like this when I need the right test ports, pressures, and teardown order so I don't waste a day and a pile of parts. If you're trying to keep downtime and guesswork low, this is the book you work from.

What this manual helps you do

  • Diagnose weak drive, slow hydraulics, or no-move issues by checking the hydrostatic and main hydraulic systems
  • Trace, test, and repair electrical and starting/charging problems using wiring diagrams and step-by-step checks
  • Follow teardown and reassembly procedures for the loader, backhoe, cylinders, and drivetrain components
  • Set and verify adjustments on linkages, brakes, loader/backhoe controls, and safety interlocks
  • Replace and pressure-test hydraulic components and hoses with the correct sequences and specs in hand

Who this is for

This is for owners and mechanics working on a Bobcat B100 backhoe loader in the serial range 572111001 to 572199999 who actually turn wrenches. If you just need basic controls, fluid types, and daily checks, you want the operator's handbook instead, not this service manual.

FAQ

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

A: Yes, it's a PDF you can search by keyword, and the wiring diagrams are clear enough to zoom in and follow circuits on a laptop or tablet.

Q: How do I know if it fits my B100?

A: Check your serial number plate. If it falls between 572111001 and 572199999, this is the right service manual.

Q: Is this what I need to rebuild and troubleshoot, or is it just parts pictures?

A: This is the workshop service manual, so it covers procedures and diagnostics, not just exploded views like a parts catalog.

Bottom line: If your B100's serial number is in that range and you're actually repairing or diagnosing it, this is the right manual. If you only want operating tips, it's the wrong one.
