Bobcat S150, S160 2006 Service Manual – Factory Specs for Skid-Steer Loaders

Look, I’ve seen too many guys crack open a PDF from some third-party site and end up with a bolt through the oil pan because the torque spec was off. The Bobcat S150, S160 2006 Service Manual here is the factory print – 694 pages of what Bobcat actually ships to dealers. No editing, no redaction, no guesswork. If you’re wrenching on one of these skid-steers, you want the documentation the factory uses, not some aftermarket rewrite that hides the real numbers.

Safety Instructions and Fire Prevention: Why It’s Page 1

Bobcat doesn’t put safety in the back of the book. The first section after the foreword is Safety Instructions, including Fire Prevention. Read it. The manual calls out that you never service the loader without instructions. It also covers exhaust fume leaks that can kill without warning – that’s not hyperbole. Page 1 also gives the serial number ranges: S/N 523811001 & Above for the S150, S/N 523911001 & Above for the S160. If your machine falls outside those ranges, this manual won’t match. Check first.

Lifting and Blocking the Loader – Not Optional

Under Safety and Maintenance, this manual walks you through the Lift Arm Support Device installation step by step. It tells you the correct procedure for raising and lowering the operator cab. There’s even a section on Emergency Exit. If you skip the lift arm support device and go under a raised loader, you’re asking for a hospital visit. The manual is clear: replace the device if damaged. That’s not a suggestion.

Hydraulic System Schematics and Troubleshooting

The Hydraulic System chapter starts with Hydraulic/Hydrostatic Schematics – actual line drawings, not blurry scans. Then it gives you Tighten Procedures and a Troubleshooting Chart. For the Main Relief Valve, you get checking, adjustment, removal and installation. The BICS™ Valve sections cover solenoid testing, lock valve removal, and check valve work. If you’re chasing a hydraulic issue, this is where you start. Don’t waste time guessing which line is pressure or return – it’s all right there.

Engine Lubrication System: Oil Chart and Filter Replacement

Engine work is covered in the Engine Lubrication System section. You get an oil chart with viscosities, the procedure for checking oil, and the full replacement steps for oil and filter. The manual tells you to stop, cool, and clean the engine of flammable materials before checking fluids – common sense, but easy to ignore when you’re in a hurry. The factory specs for the engine oil capacity are in there. If you need the Engine section pulled out separately, check the Bobcat S150 S160 2006 Service Manual – Section: Engine.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, serial number accuracy. This manual lists the loader serial number and engine serial number locations. Aftermarket reprints often mix up the numbers or leave them out. Second, torque values are factory-tested. The hydraulic system tighten procedures come straight from Bobcat’s engineering. Third, safety procedures like the lift arm support device and BICS™ Interlock Control System are included exactly as written. Aftermarket manuals cut corners on safety warnings to save paper. This one doesn’t.

For related machines, the Bobcat S150 S160 2006 Service Manual is the full document. If you need the 2008 revision for the same models, the Bobcat S150 S160 2008 Service Manual – Section: Engine Lubrication System covers that year’s updates. For other equipment types, a Manual Transmission manual has its own set of specs, but don’t mix them up with hydraulic drive stuff.

FAQ – Two Common Questions

Does this manual cover both the Bobcat S150 and S160?

Yes. It covers both models from the serial number ranges listed on page 1. The content is common to both machines except where noted.

What about torque specs for the hydraulic control valve?

The Hydraulic System Information section includes a full tighten procedures chart with torque values for all hydraulic components. You’ll find the Main Relief Valve adjustment torque, port relief valve specs, and the BICS valve solenoid torque. The troubleshooting chart on that same section helps you diagnose leaks before you break out the wrenches. If you need a Manual Transmission spec, that’s a different manual – this one is strictly skid-steer hydraulics and drivetrain.

You’re not going to find this level of detail in a generic repair book. This is the same binder that Bobcat dealers pull off the shelf when a machine comes in with a problem. Access the Factory Manual and get the right data on your bench before you turn a wrench.
