Bobcat S175 2008 Service Manual

Aftermarket manuals will get you close, but close doesn’t cut it when you’re torquing head bolts on a Bobcat S175. You need the factory numbers. The Bobcat S175 2008 Service Manual is the exact document the dealership techs use. Not a reprint, not a photocopy—original OEM print with all 873 pages. Page 1 shows the serial number range A3L511001-A3L519999 so you know it matches your machine. If you’ve ever wasted an afternoon chasing a hydraulic leak because the aftermarket schematic had the wrong port, you’ll understand why this manual stays on my workbench.

I’ve been turning wrenches for 28 years, and I’ve seen cheap manuals cause blown engines and burned wiring. This one is different. It was printed in 2008 by Bobcat Company for dealer use only—dealer copy, not for resale. That means every torque spec, every clearance, every wire color came from the engineering floor.

Fire Prevention: More Than a Warning Label

The manual opens with a serious section on fire prevention under the MAINTENANCE SAFETY chapter. It covers maintenance, operation, electrical, hydraulic system, fueling, starting, spark arrestor exhaust system, welding and grinding, and fire extinguishers. I’ve had too many calls from guys who skipped the part about cleaning the spark arrestor muffler and ended up with a grass fire. Page 3 lists the alphabetical index, but the fire prevention content is drilled into the first few sections. Read it. Your machine will still be there tomorrow.

Hydraulic/Hydrostatic System: Factory Schematics and Troubleshooting

This manual devotes a full section to the hydraulic/hydrostatic system, including schematics, a glossary of hydraulic/hydrostatic symbols, and troubleshooting. You get cylinder testing procedures for lift, tilt, and Bob-Tach cylinders, plus disassembly and assembly steps. The main relief valve testing and adjusting procedure is spelled out so you don’t overshoot pressure and blow a seal. There’s also coverage of the hydraulic control valve, load check valves, anti-cavitation valves, and port relief valves. Aftermarket manuals often skip the anti-cavitation valve removal steps—here each one is listed separately for lift rod end, base end, tilt rod end, and base end. That level of detail saves you from buying parts you don’t need.

Does the Manual Cover the Electrical System?

Yes, and it’s thorough. The ELECTRICAL SYSTEM INFORMATION chapter, plus sections on the Bobcat Interlock Control System (BICS), Bobcat Controller, alternator, battery, and diagnostic service codes. The manual includes calibration procedures, electronic/hydraulic controls for standard and SJC models, and wiring flow for the air conditioning system. If you’re chasing a no-start or a controller fault, you need this manual. I’ve used it to pin out a BICS fault that had three shops stumped. The factory wiring diagrams are indexed clearly—no guessing which wire goes where.

Engine Cooling System: Cleaning and Coolant Replacement

The ENGINE COOLING SYSTEM section covers cleaning, checking level, and removing and replacing coolant. It’s paired with the ENGINE LUBRICATION SYSTEM that includes oil charts and filter replacement. The engine serial number location is documented, so you can verify which engine variant you have. The air cleaner service section includes replacing filter elements—both primary and secondary. These are routine jobs, but doing them wrong can cost you an engine. The manual gives you the exact steps, no assumptions.

873 Pages – Where the Details Live

Let’s talk about the size. 873 pages is not a quick read, but it’s a complete reference. The alphabetical index on page 3 lets you jump straight to the component you need. From ACCESS PANEL to CYLINDER HEAD, it’s all there. Need charge pressure specs? Section 30-01. Brake service? Sections 40-01 for single and two-speed. Chaincase? Section 40-01. The manual doesn’t waste ink on fluff—every page is a specification or a procedure. That’s why I recommend it to guys who work on their own equipment. You pay once, you use it for years.

OEM vs. Aftermarket: The Difference in Your Wrench

I’ve said it before: aftermarket manuals are dangerous. They copy errors from previous editions, they omit safety notices, and they often use generic illustrations. This Bobcat Service Manual is OEM, printed by Bobcat Company in 2008. The torque values come from the factory, not from a third-party editor who never turned a bolt. If you’re serious about keeping your S175 running, you don’t compromise on documentation. The manual includes serial number locations, delivery report forms, and loader identification—all factory checkpoints.

For example, the manual covers the remote start tool kit MEL1563 and the later service tool kit 6689779. The procedure for remote start is documented step by step, including the service tool harness control and communicator. That kind of detail allows you to run diagnostic cycles without the key fob—something aftermarket manuals always skip.

Period.

Now, about the transmission: Unlike a car’s Manual Transmission, the Bobcat uses a hydrostatic drive with a final drive chaincase. But if you need to understand gear ratios or chain tension, the manual covers that in the DRIVE COMPONENTS chapter. And if you’re comparing the Bobcat’s hydrostatic system to a traditional Manual Transmission for a different project, the hydraulic/hydrostatic schematics here will give you a clear picture of how power flows through the pumps and motors.

Frequently Asked Questions

Is this manual a reprint or a scanned copy?

It’s the original OEM printer file delivered as a digital PDF. Page 1 states “Dealer Copy — Not for Resale,” and the file is identical to what Bobcat dealerships received in 2008.

Does the manual cover both the S175 and the S185 models?

This specific manual is for the Bobcat S175 with serial numbers A3L511001-A3L519999. The related products Bobcat S175 S185 Service Manual and Bobcat S175 S185 2008 Service Manual cover multiple models, but this one is dedicated to the S175. If you have an S185, get the combined manual.

What engine specifications are included?

The ENGINE section covers cylinder head, camshaft and timing gears, crankshaft and pistons, cooling system, lubrication system, and fuel system. It includes oil charts, coolant capacities, and filter part numbers.

Can I use this manual for a 2009 Bobcat S175?

Only if the 2009 unit falls within the serial number range listed on page 1. Bobcat changes the manual by serial number break, not by model year. Check your machine’s serial number against A3L511001-A3L519999. If it doesn’t match, look for the later revision. The manual’s 2008 publication date means updates after that year are not included, but most components are identical.

If you’re doing a hydraulic valve rebuild, an engine overhaul, or just a routine fluid change, you need the factory specs. Access the Factory Manual now and keep your S175 running like it left the assembly line. For more coverage, check Bobcat S175 2008 Service Manual – OEM Factory Repair Specs.
