Bobcat S150, S160 2008 Service Manual

If you’re working on a Bobcat S150 or S160 skid-steer loader from 2008, you need the factory service manual, not some aftermarket reprint that guesses on torque values. I’ve seen too many techs strip threads because they trusted a third-party PDF. This manual is 961 pages of OEM specs, direct from Bobcat. Bobcat S150, S160 2008 Service Manual covers the Engine, Electrical, Hydraulic systems, and everything else that keeps these machines running. Page 1 starts with the Bobcat Interlock Control System (BICS) – that safety feature you’d better understand before you start any service work.

Fire Prevention and Safety – Chapter Details

The manual opens with a full SAFETY INSTRUCTIONS section, then dives into FIRE PREVENTION with dedicated subsections for Maintenance, Operation, Electrical, Hydraulic System, Fueling, Starting, and even Welding And Grinding. Most guys skip this, but I’ve seen a loader go up because someone ignored the spark arrestor cleaning procedure. Read it. The manual also covers the Spark Arrestor Exhaust System and Fire Extinguishers. If you’re welding near hydraulic lines, you need the precautions listed here.

What Does the Engine Lubrication System Section Cover?

You get the ENGINE LUBRICATION SYSTEM with oil checking procedures, an Engine Oil Chart, and removal/replacement of oil and filter. The chart lists the exact viscosity and capacity for different ambient temperatures. No guessing. The manual also includes Removing Air From The Fuel System – a step a lot of guys mess up because they crack the wrong line. Follow the procedure and you won’t spend an hour bleeding air.

961 Pages of Factory Procedures

That 961 pages is not padding. You get serial number locations (loader and engine), delivery report forms, lifting and blocking the loader procedures, and the correct way to use the Lift Arm Support Device. Then you move into the SERVICE SCHEDULE, AIR CLEANER SERVICE, ENGINE COOLING SYSTEM, FUEL SYSTEM, and the HYDRAULIC / HYDROSTATIC SYSTEM. Each section has step-by-step disassembly, parts identification, and the torque values that come from the Bobcat engineering department. If you need to replace hydraulic case drain filters on single-speed or two-speed loaders, it’s in there.

Hydraulic System: Testing and Adjustment

The HYDRAULIC SYSTEM chapter covers schematics, a glossary of symbols, troubleshooting, and then individual cylinder testing and overhaul for lift, tilt, and Bob-Tach cylinders. The Main Relief Valve section tells you how to test, adjust, and replace it. The Hydraulic Control Valve section has a full identification chart and step-by-step removal and installation of load check valves, anti-cavitation valves, and port relief valves. If you’ve ever had a loader that creeps down, you’ll find the fix here.

Get the Right Torque Data from the OEM Source

Torque specs are scattered throughout the manual where they belong – next to the fastener. The HYDRAULIC SYSTEM chapter includes torque for cylinder rod end pins and valve plugs. The ENGINE LUBRICATION SYSTEM lists filter cap torque. I’ve seen aftermarket manuals list a generic value that strips an aluminum housing. This one gives you the Bobcat-specified value. Don’t trust anything else.

Is this manual for the 2008 model year only?

Yes. This 2008 manual covers serial numbers listed on page 1. It does not cover earlier or later models.

Does it include wiring diagrams?

The Electrical section under FIRE PREVENTION covers electrical system safety, but the main wiring schematics are in the HYDRAULIC SYSTEM chapter under HYDRAULIC/HYDROSTATIC SCHEMATICS. The manual includes full color-coded diagrams for the S150 and S160. You’ll find connector pinouts, wire colors, and component locations. If you’re tracing a short, start there. The manual also references the Remote Start Tool Kits (MEL1563 and 6689779) with harness diagrams.

Is this a genuine OEM manual or a reprint?

This is the factory PDF distributed to Bobcat dealers. It says “Dealer Copy — Not for Resale” on page 2. You are getting the exact same document used by Bobcat service departments.

Can I use this manual for the Bobcat S175?

No. The S175 has different hydraulic and drivetrain specs. Use the Manual Transmission equivalent for the S175. For this manual, stick to the S150 and S160.

Stop wasting time chasing down specs from forums or aftermarket reprints. The 2008 Bobcat S150 and S160 service manual gives you the factory procedures, torque values, and safety warnings you need to get the job done right.
