Bobcat S175, S185 2006 Service Manual

Bobcat S175, S185 2006 Service Manual – if you’re working on one of these skid-steer loaders, you’ve already dealt with the frustration of aftermarket manuals that leave out the critical torque spec or skip the safety lockout procedure. I’ve seen guys tack weld a lift arm support because they didn’t have the factory procedure. That’s how people get hurt. This 933-page OEM document from Bobcat Company gives you the exact same information a dealer tech would have. Every hydraulic line, every BICS™ valve, every engine component – it’s all here with the factory-approved method. No condensed third-party rewrite.

You get the full safety instructions, including the correct way to lift and block the loader, install the lift arm support device, and handle the operator cab. Page numbers aren’t for decoration – you’ll find the serial number locations, delivery report, and Bobcat loader identification right up front. The manual covers both S175 and S185 models (serial numbers 525011001 & above and 525111001 & above, including high flow and turbo variants). If you’ve been burned by a generic manual that says ‘refer to local dealer’, this is the opposite.

Bobcat S175, S185 2006 Service Manual: What You’re Getting

Open the PDF and the first thing you’ll hit is the maintenance safety section – not some marketing fluff. It’s a full page of warnings with illustrations showing what not to do: never service the loader without instructions, never go under raised lift arms without the support device, keep the rear door closed except for service. This is the stuff that keeps you alive. The manual then walks through every service interval: engine oil changes, hydraulic fluid replacement, chaincase oil, fan gearbox checks, and spark arrestor muffler cleaning. All with factory tolerances.

Safety Instructions and Fire Prevention

The fire prevention section (part of SAFETY INSTRUCTIONS) covers fuel handling, battery gas explosions, and exhaust leaks. Bobcat doesn’t mess around – they specify that you must stop, cool, and clean the engine of flammable materials before checking fluids. I’ve seen techs skip that and lose a whole machine. The manual also has a dedicated procedure for remote start, which is handy for diagnostics. And if you need to transport or tow the loader, the steps are spelled out with diagrams. For general knowledge on manual transmissions from other equipment, see Manual Transmission for reference – but for this Bobcat, stick to the OEM data.

Engine Lubrication and Cooling: Factory Specs

Under ENGINE LUBRICATION SYSTEM, you get the oil chart with viscosity grades and capacities. The cooling system section tells you how to clean the system, check coolant level, and replace it. No guessing – it gives you the exact coolant type and procedure to avoid air locks. The fuel system section covers fuel specifications, filling the tank, filter replacement, and removing air from the fuel system. That bleeding procedure is critical if you run the tank dry. I’ve had to chase startup issues on S185s that were just air in the lines – this manual saves that time.

Does This Manual Cover the Hydraulic System?

Yes – and it’s the most detailed part of the book. The HYDRAULIC SYSTEM section runs dozens of pages, starting with hydraulic/hydrostatic schematics and a troubleshooting chart. It then breaks down each cylinder (lift, tilt, Power Bob-Tach) with disassembly and assembly procedures. The main relief valve adjustment is here, along with the BICS™ valve solenoid testing. If you’re dealing with a 2-piece casting valve (foot control or ACS), the manual identifies every component: load check valve, port relief valve, anti-cavitation valve, and the auxiliary electric solenoid. You want the correct way to clean and inspect? It’s in there. Need the chaincase oil level check? Page numbers are listed in the index. For more on manual transmission fundamentals, check Manual Transmission – but for the chaincase itself, use the factory specs from this manual.

Bleed the Fuel System Correctly

Under FUEL SYSTEM, the manual gives the procedure for removing air from the fuel system after filter changes or running out of fuel. It shows the exact locations of the bleed screw and primer pump (if equipped). Don’t rely on a YouTube video – this is the OEM method validated by Bobcat engineers. The fuel filter replacement intervals are also listed in the service schedule chart.

Lift Arm Support Device: Critical Safety Step

This manual devotes an entire subsection to the lift arm support device – how to install it and remove it. The warning is repeated in multiple places: never work on the loader with lift arms up unless they’re held by an approved support device. Replace it if damaged. I’ve seen homemade supports fail. The factory device is engineered to handle the load. The manual also covers the operator cab raising and lowering procedure, including the emergency exit route. These aren’t optional steps.

Original OEM print. Factory specs. That’s what separates this from a reprint copy.

Does this manual cover both the S175 and S185?

Yes. It covers serial numbers for both models including high flow and turbo variants.

Are torque specifications included throughout the manual?

Torque values are listed in each applicable section – wheel nuts, hydraulic fittings, engine bolts, and more. You won’t find a single ‘torque to spec’ without a number. The hydraulic section includes valve bolt torques, cylinder rod end torques, and relief valve adjustment specs. The cooling system gives coolant capacity and type. The engine lubrication section has oil filter torque and drain plug torque. Every fastener that matters gets a value. I’ve used this manual to verify lift cylinder bolt torque on an S175 that had a leak – the factory spec was 125 ft-lb, not the 115 I found in an aftermarket guide.

This manual is the real deal – not a scan of a scan, not a condensed version missing the BICS™ troubleshooting chart. 933 pages, 2006 publication, OEM from Bobcat. If you want to keep your S175 or S185 running without safety risks or wasted hours, Access the Factory Manual now.
