Bobcat T320 2008 Service Manual

I’m Mike Callahan. Twenty-eight years turning wrenches, 12 of them running a six-bay shop in San Antonio. I’ve seen more stripped bolts and leaking relief valves than I care to count – usually because somebody grabbed a third-party PDF instead of the factory book. The Bobcat T320 2008 Service Manual is 934 pages of the real deal. No reprints, no condensed versions, no missing pages. This is the dealer copy Bobcat issued in 2008 for serial numbers A7MP60001 & Above and AAKZ11001 & Above. If you’re working on a T320, this is the baseline.

Fire Prevention Section: What the Manual Tells You

Page 1 of this manual carries a warning I’ve seen too many guys ignore: never work on the loader with lift arms up unless you’ve got an approved lift arm support device. That’s not a suggestion. The Fire Prevention section breaks down maintenance, operation, electrical, hydraulic system, fueling, starting, spark arrestor exhaust, welding and grinding, and fire extinguishers. Every one of those topics is covered with Bobcat’s original factory wording. If you’re welding near hydraulic lines, the manual tells you exactly what to disconnect. No guesswork.

What Torque Specs Are Included?

Torque values are scattered through the chapters – not collected in one table like some aftermarket books do. You’ll find them inside the removal and installation procedures for cylinders, valves, and the main relief valve. The manual doesn’t hide them. For example, the Main Relief Valve section includes testing, adjusting, and removal with the correct torque for the locknut. If you’re rebuilding the tilt cylinder, the assembly procedure gives you the rod-end nut torque. You have to read the manual, but it’s all there – OEM numbers, not some generic range.

Hydraulic / Hydrostatic System: Full Overhaul Procedures

The hydraulic system chapter is thick. It starts with hydraulic/hydrostatic schematics and a glossary of symbols – if you can’t read a schematic, learn before you start. Then it walks through each cylinder: lift, tilt, and Bob-Tach. Each one includes testing, removal and installation, parts identification, disassembly, and assembly. The Main Relief Valve section has its own subchapter with adjusting procedure. The Hydraulic Control Valve (Standard) section is a monster: identification chart, load check valves, anti-cavitation valves, port relief valves, spool removal – it’s all broken down by component. You will not find this level of detail in a generic manual.

Electrical System: Bobcat Interlock Control System (BICS)

Electrical diagnostics are covered in the Service Tools section and throughout the operator cab wiring. The manual includes Remote Start Tool procedures for kits MEL1563 and 6689779, with harness part numbers and step-by-step connection diagrams. If your T320 has a cab door sensor fault or the BICS system locks you out, the manual tells you how to test the circuit. No wiring schematics for the entire machine are listed in the TOC, but the BICS electrical components, cab sensors, and remote start harnesses are documented. For a machine this size, that’s where 90% of electrical issues live.

Engine Service and Lubrication Schedule

The Engine section covers coolant system, fuel system, and lubrication system. The manual specifies biodiesel blend fuel compatibility, gives you an engine oil chart, and walks through removing air from the fuel system after a filter change. The Service Schedule chart shows intervals for every fluid and filter. If you’re doing an oil change, the manual tells you the exact oil capacity and filter part number. Don’t trust an internet forum. Use the factory oil chart on the page.

3 Reasons to Stick with OEM Documentation

First, aftermarket manuals compress content – they’ll skip the “breather cap” inspection or the forestry door window kit maintenance because those sections don’t apply to every machine. Second, torque values from third-party sources are often converted wrong or pulled from a similar model. Third, the safety warnings in this manual are written for the specific machine. The lift arm support device instructions, the spark arrestor muffler cleaning – if you skip those because your generic manual didn’t mention them, you’re inviting a hydraulic spray or a fire. Dealers use this book for a reason.

FAQ

Does this manual include wiring diagrams?

The manual covers the Bobcat Interlock Control System, remote start harnesses, and cab door sensor circuits, but full machine wiring diagrams are not listed in the table of contents. Hydraulic schematics are included.

What serial numbers does this manual cover?

It covers T320 serial numbers A7MP60001 & Above and AAKZ11001 & Above. Check your machine’s serial plate before buying.

How many pages is the manual?

934 pages.

How is this different from a third-party repair manual?

Third-party manuals are often rewritten from the same source but leave out sections like the forestry door kit inspection, spark arrestor muffler cleaning, and specific parts identification for Bob-Tach cylinders. They also tend to combine multiple models, which means some torque values or adjustments don’t match your exact machine. This is the original dealer copy – every page matches what Bobcat printed in 2008. You get the exact disassembly sequence for the hydraulic control valve spools, the exact part numbers for service tool harnesses, and the exact safety warnings that Bobcat engineers wrote. If you rely on a third-party book, you’re trusting someone else’s interpretation. I don’t do that in my shop.
