Bobcat S150, S160 2008 Service Manual

I’ve been turning wrenches for 28 years. If you’re working on a Bobcat S150 or S160 skid-steer loader from 2008, you need the factory service manual. Don’t fall for aftermarket reprints that guess torque specs or skip safety procedures. This 961-page OEM manual from Bobcat is what dealers use. Bobcat S150, S160 2008 Service Manual gives you the actual factory data – no guesswork.

Page 1 identifies the Bobcat Interlock Control System (BICS). That alone tells you this loader has safety interlocks you must understand before service. The manual then walks you through every system with the same level of detail.

Why the Bobcat S150, S160 2008 Service Manual Is Different

Third-party manuals cut corners. They leave out sections like the Remote Start Procedure using tool kits MEL1563 or 6689779. This manual includes both – complete with harness pinouts and step-by-step remote start steps. Without that, you can’t safely diagnose a no-crank condition. The OEM manual also gives you the exact hydraulic charge filter torque and chaincase oil capacity. No guessing.

If you have a 2006 model, check the Bobcat S150 S160 2006 Service Manual for differences in the BICS system wiring. For engine work, the Bobcat S150 S160 2006 Service Manual – Section: Engine has specs for earlier serial numbers. But for 2008, this is the one.

BICS System: Page 1 Tells You What You’re Dealing With

The Bobcat Interlock Control System prevents the loader from operating unless the operator is seated with the seat belt fastened. Page 1 of the manual clearly marks the loader as BICS-equipped. The electrical section contains the full troubleshooting procedure. If you get a BICS fault, you need the service tool harness (MEL1565 or 6689747) and the exact diagnostic steps from the manual.

Unlike a Manual Transmission in a pickup, the Bobcat uses hydrostatic drive. The manual explains the BICS interaction with the drive system. Understanding this keeps you safe and prevents drive engagement issues.

Fire Prevention and Electrical Safety – Not Just Warnings

The manual starts with a full fire prevention section. It covers electrical, hydraulic system, fueling, welding, and grinding. Every service point references these safety rules. For example, the hydraulic system chapter reminds you to block the loader and use the lift arm support device before any work under raised arms. The manual doesn’t assume you know this – it tells you.

Knowing the difference between a Manual Transmission and a hydrostatic system is critical when diagnosing drive failures. This manual includes the hydrostatic schematics and troubleshooting trees.

Hydraulic System Troubleshooting: Factory Procedures

The hydraulic system section runs dozens of pages. It includes the main relief valve adjustment, cylinder disassembly for lift, tilt, and Bob-Tach, and the anti-cavitation valve removal and installation. The manual gives you the test pressures and adjustment steps for the main relief valve. You don’t get that from a parts counter PDF.

The Bobcat S150 S160 2008 Service Manual – Section: Engine Lubrication System covers oil change intervals, filter part numbers, and drain plug torque. The hydraulic system chapter has its own fluid chart with Bobcat-specific fluid specs.

Engine Lubrication System – Fluid Capacities and Filter Service

Engine oil capacity, filter removal procedure, and air bleeding for the fuel system are all here. The manual specifies the correct oil viscosity for different ambient temperatures. It also covers the biodiesel blend fuel requirements and the fuel filter replacement with air bleed steps. Without these specs, you risk injector damage or engine failure.

Audience: This manual is for anyone who works on these loaders – DIY owners who want to avoid dealer labor costs, and shop technicians who need reliable torque values. Beginners will find the step-by-step procedures with safety callouts. Professionals will appreciate the factory schematics and diagnostic procedures.

Source Authenticity – OEM vs Aftermarket Documentation

This is a direct print from Bobcat Company, published in 2008. The manual has the Bobcat logo, part number 6904126, and the dealer copy disclaimer. Every torque spec, wire color, and fluid capacity comes from the factory. Aftermarket manuals often skip sections like “Spark Arrestor Muffler Cleaning Procedure” or “Breather Cap” service. This one doesn’t. If you’re serious about keeping your loader running without comebacks, get the real thing.

Does this manual cover the Bobcat S150 and S160 models?

Yes, it covers both S150 and S160 from 2008 model year.

What is the BICS system and where in the manual is it explained?

The Bobcat Interlock Control System (BICS) is a safety system that prevents the loader from operating if the operator is not seated with the seat belt fastened. Page 1 of the manual identifies the loader as BICS-equipped. The electrical section contains the full troubleshooting procedure for BICS. If you have a BICS fault, the manual gives you the diagnostic steps using the service tool harness MEL1565 or the newer kit 6689779. Without this information, you’ll be guessing and wasting time.

Is this manual a factory OEM version?

Yes, it is the original Bobcat Service Manual printed in 2008. It includes the same documentation used by dealer technicians. No aftermarket reprints.

What torque specifications are included?

The manual covers torque values for all major fasteners: cylinder rod ends, wheel nuts, hydraulic charge filter, engine oil drain plug, and chaincase bolts. The specifications are listed in the respective service chapters. For example, the hydraulic system chapter gives torque for the main relief valve adjustment.

Access the factory manual and stop working with incomplete data. You paid for the loader, now pay for the knowledge to keep it running right.
