Bobcat S150, S160 2006 Service Manual – What the Dealer Uses

I’ve been an ASE Master Tech for 28 years, and I’ve seen more comebacks caused by wrong torque specs than I care to count. If you’re digging into a Bobcat S150, S160 2006 Service Manual, you don’t need a reprint that skips the critical steps. You need the original factory document – the same 694-page binder the dealer techs pull off the shelf. This is that manual.

Page 1 spells it out clear: never service the loader without instructions. That’s not lawyer talk. It means you follow the OEM sequence for bleeding the fuel system, for torquing the wheel nuts, for setting the main relief valve. Aftermarket manuals leave out the tighten procedures and the BICS™ valve lock-out steps. This one doesn’t. Every job – from a simple oil change to pulling the hydraulic control valve – has a numbered procedure, a tool list, and factory tolerances.

694 Pages of Factory Data – No Guesswork

You’re holding 694 pages of what Bobcat’s engineers wrote for the S150 and S160 Turbo models (serial numbers starting 523811001 and up). The table of contents alone covers every system: Engine Cooling System, Fuel System, Hydraulic/Hydrostatic System, Final Drive Transmission, Fan Gearbox, Bob-Tach, and the full Hydraulic System section with schematics. Need to pull a tilt cylinder? The manual gives you the removal-and-installation steps plus the disassembly sequence. It also tells you which seal kit to use – no more head-scratching over part numbers.

Safety Instructions – Page 1 Warning You Can’t Ignore

Before you touch a wrench, read the safety section. Page 1 warns about lift arm support devices, hydraulic fluid injection, and battery acid. I’ve had guys skip the lift arm support because they were in a hurry. That’s how people get crushed. This manual shows you the approved lift arm support device installation and removal procedures – step by step. It also covers the operator cab raising/lowering, emergency exit, and the exact way to block the loader. Ignoring these warnings costs more than money.

Hydraulic System Information – Torque and Troubleshooting

The Hydraulic System section is the thickest part of this manual for a reason. It includes tighten procedures (not just “tighten to spec” – actual ft-lb values), a troubleshooting chart, and schematics for both foot control and ACS (Advanced Control System) valves. You get the BICS™ valve removal, solenoid testing, and check valve replacement. If you’ve ever fought a hydraulic leak or a slow lift, you know the difference between a factory spec and a guess. This manual ends the guessing.

Engine Cooling and Lubrication – Don’t Skip the Cleaning

The Engine Cooling System chapter tells you to clean the system and check the coolant level. Sounds basic, but the manual gives you the full flushing procedure and the coolant replacement frequency. The Engine Lubrication System section has the oil chart, filter replacement, and the exact way to check engine oil on these Bobcat loaders. Every fluid spec – fuel, hydraulic, chaincase oil – is listed with the correct type and capacity. You won’t find that in a generic manual.

Why You Need the OEM Manual – Not a Copy

I’ve seen aftermarket “service manuals” that reprint the same page twice or leave out the BICS valve lock-out section. That’s dangerous. This manual is the original Bobcat publication, printed in the USA for dealer use. The wiring diagrams are legible, the torque values are original, and the safety warnings are complete. If you want to keep your S150 or S160 running without chasing leaks or replacing parts twice, this is the only source you should trust.

FAQ

Does this manual cover both the Bobcat S150 and S160 models?

Yes. It covers S150 and S160 Turbo units with the serial number ranges listed on page 1. S200 or other models are not included.

What kind of torque specifications are included?

Factory-specified torque values for every fastener – wheel nuts, hydraulic fittings, cylinder rod end nuts, BICS valve bolts, and lift arm pivot pins. The Hydraulic System Information section gives tighten procedures in ft-lb. No generic ranges: these are the numbers Bobcat stamped on the assembly line. Using the wrong torque on a main relief valve can cause a seal blowout. This manual keeps that from happening.

How is the manual organized?

It starts with safety instructions and serial number locations, then a delivery report form. After that, the Safety and Maintenance section covers lifting, cab, transport, and towing. Then scheduled maintenance with charts. Then deep dives into the engine, fuel, hydraulic, cooling, and final drive systems. Each chapter has checking, removal, installation, disassembly, and assembly steps. Schematics and troubleshooting are in the hydraulic section.

Can a home garage mechanic use this manual?

Yes. The language is direct, steps are numbered, and tool lists are included. If you can read a torque wrench and follow a sequence, you can do the work. I’d still recommend reading the safety warnings twice – they’re there for a reason. Beginners should start with the maintenance sections before tackling valve disassembly.
