Bobcat S175 2008 Service Manual

I’ve been turning wrenches for 28 years. You learn to spot a manual that was written by someone who actually took a loader apart versus one assembled from guesswork. The Bobcat S175 2008 Service Manual is the real deal. It’s 878 pages of factory procedure, not aftermarket fluff. If you’ve ever had a skid-steer down because a third-party spec had the wrong torque on a cylinder rod end, you know why this matters.

Fire Prevention: Electrical and Hydraulic System Safety

Page 3 of this manual lays out the safety instructions that Bobcat expects every tech to follow before touching the machine. It covers fire prevention for the electrical system, hydraulic system, fueling, welding and grinding. I’ve seen guys skip the step about disconnecting the battery before working on the electrical side and fry a controller. That’s a $1,000 mistake. The manual doesn’t assume you know—it tells you the exact sequence. The section on hydraulic system fire prevention alone will save you from burning up a $30,000 loader. These are not generic warnings; they’re specific to the S175’s layout.

What Does the Fuel System Section Cover?

Fuel system work gets sloppy fast when you don’t have the right spec. The manual gives you fuel specifications, including biodiesel blend fuel requirements, the correct fuel filter part numbers, and the procedure for removing air from the fuel system after a filter change. I’ve watched guys crank a diesel for ten minutes because they didn’t know the proper bleed sequence. That kills starter motors. The S175’s injection system is sensitive—wrong pressure after a filter change can cause hard start or misfire. This section tells you the exact steps.

3 Reasons to Choose OEM Documentation

First, the torque values come from Bobcat’s engineers, not a reprint house guessing from a photo. Second, the safety warnings match the actual loader configuration—aftermarket manuals often skip the BICS™ system warnings. Third, the troubleshooting charts are based on factory test data. When the manual says “check charge pressure if hydraulic system hesitates,” that’s a specific number, not a range. Aftermarket manuals give you a range because they don’t know the exact spec. That costs you time and parts.

Get the Right Hydraulic Relief Valve Setting

The hydraulic system section includes the main relief valve description, testing, adjusting, and removal and installation. If your S175’s auxiliary hydraulics are weak, you can adjust the relief valve to spec without guessing. The manual gives you the exact pressure setting and the tool required. I’ve seen a shop replace an entire pump because they set the relief valve too high and blew a seal. The step-by-step procedure on adjusting the valve includes the mandatory safety step to block the lift arms first—something a lot of guys skip. Don’t be that guy.

Engine Cooling System: Cleaning and Coolant Replacement

Overheating a Bobcat S175 in a Texas summer will warp a head faster than you can say “head gasket.” The manual covers cleaning the cooling system, checking coolant level, and the full removal and replacement procedure. It specifies the coolant type and the bleed procedure for the engine. I always tell guys to flush the system every two years, but the manual’s service schedule chart (in the service schedule section) tells you exactly when based on hours. Follow that chart. Engines are expensive.

Page 1 of the manual identifies your loader by serial number location—both loader and engine serial numbers. That’s critical when ordering parts. If you call a dealer and give them the wrong serial number, you’ll get the wrong part. The manual shows you exactly where to find those numbers on an S175.

Before you download the manual, check that your model matches: S/N A3L520001 and above. This edition is from 2008 and covers that range. It includes the BICS™ interlock control system, which is a critical safety feature. If you’re working on an older machine without BICS, you need a different manual.

Does this manual cover the electrical system?

Yes, including fire prevention procedures for electrical components and hydraulic/hydrostatic schematics.

What torque values are listed in the manual?

The manual includes OEM torque specifications for critical fasteners such as wheel nuts (see tire maintenance section), cylinder pivot pins, hydraulic valve mount bolts, and engine mounting bolts. These are not generic values—each spec is tested for the S175’s specific materials and thread types. Using aftermarket torque values on a Bobcat can cause fastener failure or fluid leaks. The manual’s torque specs are the same ones used in the factory assembly line. I’ve had apprentices try to use generic charts and strip threads; this manual prevents that. For wheel nut torque, the manual provides the exact ft-lbs required for the S175’s rims.

Is this manual suitable for a beginner?

If you can read a torque wrench and follow numbered steps, yes. The manual assumes you have basic tools and common sense. It does not assume you know the loader’s systems. Each procedure starts with required tool lists and safety warnings. The language is direct, not engineering jargon. I’ve taught high school kids using these manuals.

How many pages does the manual have?

878 pages, published in 2008. It covers everything from delivery report to storage procedures.

I’ve been turning wrenches for 28 years, and the one thing that separates a repair from a disaster is having the factory spec sitting next to you. Bobcat S175 2008 Service Manual is exactly that – the same 873-page book that Bobcat dealers keep behind the counter. This isn’t a third-party rewrite. It’s the original OEM print from 2008, covering serial numbers A3L511001 through A3L519999. No generic diagrams. No missing torque values. Just the procedure the factory wants you to follow.

What’s Inside: 873 Pages of Factory Procedures

This manual starts with a full Safety Instructions chapter that covers fire prevention, electrical safety, fueling, and welding precautions. Then it goes straight into serial number locations for both the loader and the Engine, delivery report forms, and loader identification. The Safety and Maintenance section alone runs through lifting and blocking, lift arm support device installation and removal, operator cab raising and lowering, cab door sensor adjustments, towing procedures, and two different remote start tool kits (MEL1563 and 6689779). Service schedules, air cleaner filter replacement, Engine Cooling System cleaning and coolant replacement, Fuel System specifications including biodiesel blends, Engine Lubrication System oil charts and filter changes – all laid out with the exact intervals you need. Section 10-01 covers the air cleaner service. Section 60-01 handles the entire electrical system information, including the Bobcat Interlock Control System (BICS).

Engine and Hydraulic System Coverage

Skid-steer loaders work hard, and the Bobcat S175 is a popular machine. The manual gives you the full breakdown on the Engine: camshaft and timing gears (section 70-01), cylinder head, crankshaft and pistons. If you’re used to working on cars with a Manual Transmission, this machine’s hydrostatic drive is a different animal – and the manual covers the hydraulic/hydrostatic system in depth. Main relief valve description, testing, adjustment, removal and installation. The hydraulic control valve (standard) gets its own sub-section with lift load check valves, anti-cavitation valves, port relief/anti-cavitation valve removal for lift and tilt circuits. Cylinder testing, removal, disassembly and assembly for lift, tilt, and Bob-Tach cylinders. Hydraulic/hydrostatic fluid charts, filter replacement for single-speed and two-speed loaders, charge pressure checks – it’s all here.

Electrical System Diagnostics

The Electrical section covers more than just battery and alternator. Diagnostics service codes, calibration procedures, ACS and SJC control systems, blower fan, air conditioning system flow, and the Bobcat Interlock Control System (BICS) troubleshooting. The manual includes wiring diagrams and component location references. If you’ve ever chased an intermittent electrical fault on a skid-steer without a schematic, you know how fast billable hours burn. This manual puts the factory diagram in your hand. Manual Transmission is a whole different world of mechanics, but when you’re working on a machine that runs through a control handle/lever and a controller, you need the exact pin-out voltages. This delivers that.

Who Needs This Manual?

If you own a Bobcat S175 and turn your own wrenches, this is the only manual you should trust. Beginners will appreciate that each procedure starts with a list of required tools and safety warnings – not assumed knowledge. DIY mechanics who have been burned by aftermarket manuals that skip steps or use wrong torque specs will find the relief here. Farm owners, small fleet operators, and rental yard mechanics: you cannot afford to guess on hydraulic relief valve adjustments or wheel nut torque. The manual includes the Bob-Tach hand lever and power Bob-Tach inspection, pivot pin lubrication, tire rotating and mounting instructions, and final drive transmission (chaincase) oil checks.

Why OEM Beats Aftermarket

I have seen aftermarket wiring diagrams that were reversed polarity. I have seen torque specs that were off by 20 ft-lbs. A third-party manual might save you twenty bucks, but it can cost you a thousand in blown seals or a cylinder rod that snaps. This manual was printed by Bobcat Company in 2008. It is a dealer copy, not for resale originally – which means it’s the exact binder that Bobcat techs used. The procedures match the service bulletins and recall notices. If you need to find the charge pressure test port or identify which hydraulic case drain filter goes where on a two-speed loader, it’s in here.

FAQ

Does this manual include torque specs for the wheel nuts?

Yes, section 10-01 covers wheel nut torque along with tire rotation and mounting procedures.

What if I need to troubleshoot the BICS system?

The electrical section, starting around section 60-01, gives you the full diagnostic tree for the Bobcat Interlock Control System. It covers component locations, wiring diagrams, service codes, and step-by-step testing from the controller to the cab door sensor. The manual also includes calibration procedures and the remote start tool kit instructions for both MEL1563 and 6689779 kits. Before you start any electrical tests, read the safety lockout procedure in the foreword – that part is non-negotiable. One wrong probe can cost you a controller module.
