Bobcat S175 2008 Service Manual – Factory OEM Specifications for Skid-Steer Loader Repair

You tear down a Bobcat S175 only to find a hydraulic leak at the main relief valve. The aftermarket manual says “tighten to spec” but doesn’t tell you which spec. That is where this factory 2008 service manual earns its keep. 878 pages of Bobcat-published data, not some third-party reprint. If you want to do this right—and avoid buying a new charge pump—you need the OEM torque values and the disassembly sequence that matches the parts you have in your hand. Bobcat S175 2008 Service Manual is the only source I trust for this loader, and I’ve seen enough junk manuals to know the difference.

Fire Prevention and Safety: What the First Pages Teach You

Most guys skip the safety section. That’s how you get a lift arm to the face or a hydraulic injection wound that sends you to the ER. This manual opens with “MAINTENANCE SAFETY” and doesn’t let up. It covers fire prevention for electrical, hydraulic, fueling, welding—the whole shop hazard list. Page 3 alone gives you the correct lift arm support procedure. Bobcat says: never work under raised arms without an approved support device. Replace it if damaged. Battery acid, exhaust fumes, moving parts—it’s all in there. Factory documentation doesn’t sugarcoat. It tells you what can kill you and how to avoid it.

Engine Cooling System – Cleaning and Coolant Replacement Procedure

Factory torque specs for engine components? They’re in here. The cooling system chapter walks you through cleaning the radiator fins, checking coolant level, and the full drain-and-fill procedure. Biodiesel blend fuel specs are also covered in the Fuel System section. If you’re replacing the water pump or thermostat, you get the OEM sequence—not a guess. I’ve seen aftermarket manuals skip the cooling system cleaning step. Bobcat didn’t.

Lift Arm Support Device – Why You Never Skip This Step

Do not go under the loader with lift arms up unless that support device is locked in place. The manual shows you installation and removal of the approved device. It even gives the part reference. One wrong move and the whole machine comes down. I’ve pulled techs off jobs for ignoring this. The manual backs me up: “Replace if damaged.” That’s non-negotiable.

Hydraulic System Schematics and Troubleshooting

Each hydraulic circuit is laid out with OEM symbols and a glossary so you can read the schematics. The troubleshooting section lists symptoms—weak lift, slow tilt, erratic bob-tach—and points you to the right valve. Main relief valve adjustment, port relief removal, anti-cavitation valve service—all with the factory pressure settings. Disassembly and assembly of lift, tilt, and bob-tach cylinders are shown with parts identification charts. You get the real spring compression specs, not a generic “reassemble in reverse order.”

Remote Start Tool Kits: MEL1563 vs 6689779 – Which One Fits?

If your S175 has the Bobcat Interlock Control System (BICS), you need a remote start tool to run diagnostics without the cab. This manual documents two kits: the older MEL1563 with three harnesses (control, communicator, service tool) and the newer 6689779 that uses a different service tool harness. The remote start procedure for each kit is spelled out step by step. Don’t try to short pins with a paper clip—you’ll fry the controller. Use the factory method.

Does This Manual Cover the Electrical System and Engine Disassembly?

Yes. The “Electrical” section under Fire Prevention includes wiring precautions and component testing guidance. The Engine chapter (engine serial number location, lubrication system, oil chart, filter replacement) gives you the full service schedule. If you need to pull the engine, the manual includes removal and installation steps for the cooling system, fuel system, and exhaust. It’s all there—878 pages of it. No shortcuts, no third-party guesses. You get Bobcat’s original printing from 2008.

Can I use this manual for the Bobcat S185 as well?

No, it is specific to the S175. See the related Bobcat S175 S185 Service Manual for that model.

Are full wiring diagrams included in this manual?

The manual covers electrical safety and component testing, but it does not contain complete harness routing diagrams. For detailed wiring schematics, you would need the Bobcat electrical schematic supplement. The manual does include the glossary of hydraulic/hydrostatic symbols and fuse locations. If you’re chasing a short, start with the component tests described in the remote start tool section—those harness pinouts are given. For a full wire-by-wire diagram, look for the separate electrical manual.

If you need a manual for a related machine, check the Bobcat S175 S185 2008 Service Manual or the Bobcat S185 Skid-Steer Loader Service Manual. For comparison to a vehicle drivetrain, the loader’s hydrostatic system is nothing like a Manual Transmission—no gears to shift, just a pump and motor. However, the same principle of using a Manual Transmission in a car involves clutch engagement, which is completely absent here. Stick with the factory manual for this machine.
