Bobcat BL370 Backhoe Loader Service Manual (SN 572711001-572799999)

This BL370 is a backhoe loader, so it's the machine you've got digging trenches, loading trucks, and doing utility work all week. The manual is what I grab around my shop when a machine is down and I need real specs and step-by-step procedures, not safety stickers. If you're chasing a hydraulic issue, doing engine work, or sorting out an electrical gremlin, this is the kind of book that keeps downtime and guesswork to a minimum.

What this manual helps you do

  • Diagnose hydraulic problems, check pressures, and trace leaks in the loader and backhoe systems
  • Follow teardown and reassembly steps on engine, transmission, axles, and driveline components
  • Troubleshoot electrical faults using wiring diagrams so you're not guessing at wires and connectors
  • Adjust and verify brake, steering, and control linkages after repairs so the machine runs straight and safe
  • Replace and set seals, bushings, and bearings in cylinders, pivots, and drivetrain without trial and error

Who this is for

This is for a small contractor, owner-operator, rental fleet, or shop mechanic who actually turns wrenches on a BL370. If you only want basic controls, daily checks, and safety info, you need the operator's handbook, not this service manual.

FAQ

Q: Is this a searchable PDF, and can you read the wiring diagrams?

A: These Bobcat service PDFs are usually text searchable, and the wiring diagrams are normally scanned clear enough to zoom in and follow circuits.

Q: How do I know if it fits my BL370?

A: Check your serial number. If it falls between 572711001 and 572799999, this is the right manual. If it doesn't, you need a different one.

Q: Is this the right document if I'm doing my own repairs?

A: Yes, if you're doing real repair work or diagnostics. For parts ordering, you'd still want the separate parts catalog.

If your BL370 serial number is in that range and you're doing your own repairs, this is the manual you want. If the serial doesn't match, skip it.
