The Bobcat 864 is a mid-size skid-steer-class loader that lives on pallets, dirt, and concrete all day. Around my yard, this is the kind of machine that's always either loading trucks or feeding attachments, so downtime hurts. People grab the service manual when they're past warranty and need real repair info, not safety stickers and fluid charts. They want torque specs, test ports, wiring colors, and step-by-step teardown so the machine goes back out clean and on time.
What this manual helps you do
- Diagnose drive and travel issues by checking hydrostatic and charge pressures with test ports and gauges
- Trace and repair electrical faults using wiring diagrams for this exact serial range
- Follow step-by-step removal and installation for pumps, drive motors, axles, and major hydraulic components
- Rebuild and reseal cylinders, valves, and Bob-Tach related hydraulics with proper disassembly and reassembly order
- Set and verify adjustments on linkages, controls, and engine-related components after repair
Who this is for
This manual is for anyone maintaining or repairing a Bobcat 864 loader in the serial range 518911001 through 518914999: small contractors, rental fleets, shop mechanics, and owner-operators who turn their own wrenches. If you only need basic operating instructions or 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: These manuals are usually scanned or native PDFs that you can search, and the wiring diagrams are laid out so you can zoom in and read pin numbers and wire colors.
Q: How do I know if it covers my exact 864?
A: Check your loader's serial plate. If it falls between 518911001 and 518914999, this is the right manual. If it doesn't, you need a different book.
Q: Is this the right document if I'm doing engine or hydraulic rebuild work?
A: Yes. This is the workshop-level service manual, which is what you want for teardown, inspection, testing, and reassembly.
Bottom line: If your 864's serial number is in that range and you're doing real repair work, this is the right manual. If your serial is outside that range, skip it.
