Bobcat 150, 160 2006 Service Manual – OEM Factory Specs

I’ve seen more shade-tree repairs go sideways on Bobcat loaders than I care to count. Usually because some guy guessed the torque on a hydraulic fitting or skipped the lift arm support device step. You don’t get a second chance when a 2,000-pound lift arm drops on your chest. That’s why the Bobcat 150, 160 2006 Service Manual sits on my bench, not some third-party reprint. It’s 929 pages of the same documentation Bobcat dealers used in 2006, with the original factory torque specs, schematics, and safety procedures. No abbreviations, no aftermarket guesswork.

Hydraulic System Breakdown: Cylinder and Valve Specs

The hydraulic section alone eats up half the manual. You get full disassembly and assembly procedures for the lift cylinder, tilt cylinder, and power Bob-Tach cylinder. The manual walks through identification charts, removal, and even the BICS™ valve solenoid testing. Need the main relief valve adjustment? It’s in there, with the exact procedure and a troubleshooting chart. I’ve used the cylinder seal replacement sequence on a 160 that was leaking down – followed the manual line by line and it held pressure first try. The torque specs for the rod end pivot pin bushing are listed right in the cylinder chapters.

Does This Manual Cover the BICS System?

Yes, and in detail. The Bobcat Interlock Control System (BICS™) is covered with removal and installation for the BICS valve, the lift arm by-pass orifice, check valve, lock valve, and solenoid. There’s a separate solenoid testing procedure. If you’ve ever had a loader that wouldn’t start because the BICS solenoid failed, you know how frustrating it is. This manual gives you the ohmmeter readings and the exact steps to diagnose it. No guessing – you verify the resistance, then decide whether to replace the solenoid or the whole valve assembly.

929 Pages of Factory Procedure

Let’s talk page count. 929 pages, printed in the U.S. by Ingersoll Rand for Bobcat Company. That’s not a condensed aftermarket pamphlet. It includes the Safety Instructions, Fire Prevention section, Serial Number Locations for both the loader and engine, Delivery Report, and Bobcat Loader Identification. The safety warnings aren’t boilerplate – they tell you exactly how to lift and block the loader, install the lift arm support device, and raise or lower the operator cab. There’s even an emergency exit procedure. You don’t get that from a PDF slapped together from scanned pages.

Engine Maintenance: Oil, Filter, and Cooling System

Engine work on the 150 and 160 models is straightforward if you have the right data. The manual covers the Engine Lubrication System with an oil chart, checking procedure, and replacement intervals. Fuel system includes specifications, filling, filter replacement, and a dedicated procedure for removing air from the fuel system – critical after a filter change. The cooling system section tells you how to clean the system, check coolant level, and replace the coolant. These are the steps that keep a diesel running for 5,000 hours instead of dying at 2,000 from neglected maintenance.

Safety and Maintenance: What You Need to Know Before You Start

The first 80 pages are all safety and maintenance. Lifting and blocking the loader, towing, remote start procedure, and a service schedule chart. The manual is adamant about using an approved lift arm support device – and it includes the part number for the correct one. I’ve seen guys use a chunk of 4×4 under the lift arms. That’s how you get killed. The manual says replace the support device if it’s damaged. That’s not a suggestion. There’s also a section on the Spark Arrestor Muffler cleaning procedure if you’re operating in fire-prone areas.

Wheel nut torque is covered in Tire Maintenance. The manual specifies the exact tightening sequence and torque for the wheel nuts – something aftermarket guides often gloss over. A loose wheel at 12 mph on a jobsite is a wreck waiting to happen. The manual also covers tire rotation and mounting. If you’re running mismatched tires, the manual will tell you why that causes driveline bind.

That’s it. No fluff, no filler. If you’re working on a Bobcat 150 or 160 and you don’t have this manual, you’re rolling the dice. I’ve been turning wrenches 28 years, and I don’t trust memory or internet forum advice on a job that pays the bills. Get the real documentation. Access the Factory Manual and keep it on your tablet or printed out. Your loader – and your hands – will thank you.

Does this manual cover both the Bobcat 150 and 160?

Yes. It covers models 150 and 160 turbo, with serial numbers 526611001 & above and 526711001 & above, respectively. The same manual applies to both models with slight differences noted in the hydraulic control valve sections.

What kind of torque specs are in this manual?

Factory OEM torque values for hydraulic fittings, wheel nuts, cylinder rod end pins, main relief valve, and more. They are listed in the troubleshooting charts and assembly procedures throughout.

Is this a printed book or a digital access?

Digital access – a 929-page PDF scanned from the original 2006 dealer manual. It’s searchable, and you can print selected pages for the workbench.

Will this manual help me diagnose a BICS system fault?

Yes. It includes BICS valve solenoid testing with resistance values, removal and installation steps, and the lock valve procedure. That section alone is worth the price if you’ve got a solenoid that won’t engage.
