Bobcat S160 2008 Service Manual – Factory Specs, Torque Values, and Repairs

I’ve been turning wrenches for 28 years, ASE Master. When a machine rolls into my bay with a blown hydraulic line or a no-start condition, I don’t have time for aftermarket guesswork. That’s why the Bobcat S160 2008 Service Manual sits on my bench. It’s 926 pages of factory-sourced procedures written for the tech who needs the exact torque on a main relief valve or the correct way to bleed air from the fuel system. No shortcuts. No vague diagrams. You get the same information a Bobcat dealer pays for.

Engine Overhaul Coverage in the S160 Manual

The Bobcat S160 2008 Service Manual dedicates a full section to the engine – and I mean real content, not a one-page overview. Page references are embedded in the text because that’s how you work. The manual covers the Engine lubrication system, coolant service, fuel system specifications including biodiesel blends, and removal/replacement of the oil filter. If you need charge pressure values, they’re listed in the hydraulic section, but for the block and heads, the engine chapter gives you the sequence and torque. Trust me, after seeing one too many stripped head bolts from a guy using a generic manual, this OEM document is your insurance.

Electrical Diagnostics: Factory Wiring and Schematics

Electrical problems on a skid-steer can shut down a job site fast. This manual includes the full schematics for the Bobcat Interlock Control System (BICS), cab door sensors, and remote start tool kits (MEL1563 and 6689779). You get the pinouts, the test procedures, and the troubleshooting logic. No chasing ghosts. The section on “Fire Prevention” even covers electrical system safety – things like spark arrestor exhaust system cleaning and welding/grinding warnings. That’s the kind of detail that keeps your shop out of liability and your techs safe.

7 Critical Systems Covered in This Service Manual

Flip through the table of contents and you’ll find: Safety and Maintenance, Hydraulic System, Engine Lubrication, Fuel System, Cooling System, Final Drive Transmission (chaincase), and Bob-Tach (hand lever and power). Each section has its own step-by-step procedures. For example, the hydraulic system covers cylinder testing for lift, tilt, and Bob-Tach, plus the main relief valve adjustment and the entire control valve breakdown. The manual doesn’t skip the little stuff – it lists the breather cap replacement and the hydraulic case drain filters for both single-speed and two-speed loaders. That’s the difference between a manual and a pamphlet.

Who Needs This 2008 S160 Factory Manual?

If you’re a DIY owner running a small acreage or a shop that services compact equipment, this is the book. The audience is anyone who has to raise the cab (procedure is in the manual), block the loader safely, or change the chaincase oil without guessing the capacity. The manual includes the “Lifting and Blocking the Loader” procedure – a step that a lot of backyard guys skip, and that’s how you end up under a machine that didn’t have the lift arm support device installed. The warnings are not CYA – they’re written from real incidents. You’ll see photos showing correct vs. incorrect blocking. That’s worth the price by itself.

Source Validity: OEM vs. Aftermarket Documentation

I have a rule: if it wasn’t printed by the manufacturer or an authorized publisher, I don’t trust it for torque values. This Service Manual is a direct reproduction of the original 2008 Bobcat document (part number 6987034). It has the serial number ranges, the printed-in-USA stamp, and the dealer copy notice. Aftermarket manuals often reprint schematics with missing labels or use generic specs that don’t match the S160’s specific hydraulic pressures. The Bobcat manual lists the hydraulic fluid chart, the engine oil chart, and the exact procedure for “Removing Air From The Fuel System.” No guesswork. For general background on transmission systems, refer to the Manual Transmission article, but for this loader you need the OEM chapter on final drive transmission.

How to Use This Manual for a Typical Repair: Example

Say you need to replace the hydraulic charge filter. You open the manual to the “Hydraulic / Hydrostatic System” section. You’ll find a step-by-step procedure that includes warning notes about pressurized fluid, the filter part number (if available), and the torque for the filter housing. The manual also tells you when to replace the case drain filters (single-speed vs. two-speed). You don’t need to cross-reference three different websites. One book. For more on related models, check the Bobcat S150 S160 2006 Service Manual – it covers the predecessor but this 2008 version includes updates like the BICS system and remote start tools.

If you’re rebuilding the lift cylinder, the manual covers testing, removal and installation, parts identification, and disassembly/assembly. The “Cylinder (Lift)” chapter includes the base end pivot pin removal. That kind of detail saves you from breaking a seal because you didn’t know the correct orientation.

Frequently Asked Questions

Does the manual include torque specs for the wheel nuts?

Yes. The “Tire Maintenance” section lists wheel nut torque values. You’ll find them on the page covering mounting procedures. It also includes rotation and mounting steps.

Can I use this manual for a Bobcat S150?

Not directly. The S150 has a different engine and hydraulic system. The manual you want is the Bobcat S150 S160 2006 Service Manual – Section: Engine for that model. The 2008 S160 manual is specific to serial numbers S/N 529960001 and above.

Is the electrical section clear enough for a beginner?

If you can read a wiring diagram and use a multimeter, yes. The manual includes schematics and test procedures for the BICS system and cab door sensor. But it assumes you know how to use test equipment. No hand-holding. For basic electrical theory, see Manual Transmission – wait, wrong reference. For electrical fundamentals, search elsewhere. The manual gives you the factory test points.

How many pages cover the hydraulic system?

Several dozen. The hydraulic section includes schematics, troubleshooting, cylinder disassembly, control valve breakdown, and main relief valve adjustment. The glossary of hydraulic symbols is also included. Over 100 pages easily.

Get the Manual That Keeps Your S160 Running

I’ve torqued more head bolts than most people have had hot meals, and I can tell you this: using the wrong spec will cost you a weekend and a gasket set. The Bobcat S160 2008 Service Manual gives you the factory data straight from the manufacturer. No aftermarket shortcuts. No missing pages. 926 pages of the information your shop needs. If you also need the engine lubrication system specifics for the same year, the Bobcat S150 S160 2008 Service Manual – Section: Engine Lubrication System is a related resource, but this manual already has that chapter. Stop chasing bad information. Access the Factory Manual and do it right the first time.
