The Bobcat 864 is a skid-steer-class loader that lives in the same world as a Cat 236 or Deere 320, running a diesel engine, hydrostatic drive, and high-flow hydraulics for buckets, augers, hammers, and so on. People grab this service manual when the 864 is out of warranty and they're done guessing, or when a field tech needs the right sequence to diagnose a no-drive, weak hydraulics, or an electrical fault. Around my shop, this is what I'd open before tearing into pumps, drive motors, or chasing wiring ghosts on an older 864.
What this manual helps you do
- Trace and troubleshoot hydraulic and hydrostatic drive problems on the 864 loader
- Check and set pressures on the main and charge circuits with proper test ports and procedures
- Follow teardown and reassembly steps for pumps, drive motors, cylinders, and major mechanicals
- Diagnose and repair electrical and wiring issues using circuit diagrams for this serial range
- Replace and adjust linkages, controls, and Bob-Tach components with correct sequences and specs
Who this is for
This is for a small contractor, owner-operator, shop mechanic, or rental fleet tech working on a Bobcat 864 in the 516911001-516999999 serial range. If you only need how to start, operate, or basic maintenance intervals, you want the operator's handbook instead, not this manual.
FAQ
Q: Is this a searchable PDF and are the wiring diagrams readable?
A: These manuals are usually supplied as searchable PDFs, and the wiring diagrams are meant to be zoomed in on a screen or printed for bench use.
Q: How do I know if it fits my exact 864?
A: Check your machine's serial tag. If it falls between 516911001 and 516999999, this is the correct service manual series.
Q: Is this the right document if I'm rebuilding or diagnosing, not just changing oil?
A: Yes, this is the workshop service manual, meant for real repair work, not routine operator maintenance.
Bottom line: If you have a Bobcat 864 in that serial range and you're doing your own diagnostics or rebuilds, this is the manual you want. If you just need basic operating info, skip it.
