Bobcat T250 2006 Service Manual

You’ve got a Bobcat T250 2006 Service Manual in your hands – the real factory print, not some aftermarket rehash. Page 1 tells you exactly which serial number range this applies to (S/N 525611001 & Above and S/N 525711001 & Above). That matters because if you grab a generic manual and it says 70 ft-lbs for the lift cylinder base pin, you might be chasing a leak that never existed. I’ve seen it happen. Wasted billable hours, bleeding air out of a system that didn’t need it. This manual stops that.

What’s Actually in This 1064-Page Manual

Most aftermarket PDFs skip half the chapters. This one covers the entire machine from the Engine out. The table of contents includes FOREWORD, SAFETY INSTRUCTIONS (Fire Prevention), SERIAL NUMBER LOCATION for both loader and engine, DELIVERY REPORT, and BOBCAT LOADER IDENTIFICATION. Then you hit SAFETY AND MAINTENANCE – that’s where you find LIFTING AND BLOCKING THE LOADER procedure, LIFT ARM SUPPORT DEVICE (engage/disengage), OPERATOR CAB raising/lowering/emergency exit, TRANSPORTING, TOWING, REMOTE START procedures (with and without attachments control harness), and the SERVICE SCHEDULE chart. Nothing’s missing.

Engine and Fuel System – Factory Procedures

Under SAFETY AND MAINTENANCE you get AIR CLEANER SERVICE (replacing filter element), ENGINE COOLING SYSTEM (cleaning, checking coolant level, adding coolant), FUEL SYSTEM with fuel specifications, filling the tank, fuel filter replacement, and the critical step of removing air from the fuel system. If you’ve ever had a diesel that won’t restart after a filter change, you know why that air-bleed procedure needs to be exact. The manual gives you the sequence. Also covers ENGINE LUBRICATION SYSTEM – checking oil, oil chart, replacing oil and filter. All with OEM tolerances.

Hydraulic/Hydrostatic System – Don’t Skip the Bleed

This is where aftermarket manuals really screw you. The HYDRAULIC/HYDROSTATIC SYSTEM section includes checking and adding fluid, hydraulic fluid chart, filter replacement, and replacing case drain filters. Then the HYDRAULIC SYSTEM chapter dives into HYDRAULIC/HYDROSTATIC SCHEMATICS, troubleshooting, and a tightening procedure. Cylinder removal and installation for lift, tilt, and power Bob-Tach – each with checking, parts identification, disassembly, and assembly. The MAIN RELIEF VALVE checking and adjustment procedure is on the money. And the HYDRAULIC CONTROL VALVE sections (foot control and ACS) break down every spool, check valve, and solenoid. If you need to rebuild that BICS™ valve, it’s all in there.

Safety and Maintenance – Lift Arm Support Device

I’ve seen techs get killed because they skipped the lift arm support. This manual covers LIFT ARM SUPPORT DEVICE engagement and disengagement step by step. Also OPERATOR CAB emergency exit – good to know before you’re pinned. LUBRICATING THE LOADER procedure with intervals. BOB-TACH and POWER BOB-TACH inspection and maintenance. FAN GEARBOX checking and adding oil. None of this is optional. The manual includes the correct safety warnings from page 1 – “Never service the Bobcat Compact Track Loader without instructions.” That’s not a suggestion.

Audience: Who Should Buy This Manual

If you own a T250 track loader and do your own maintenance, this is the only source that matches what the dealer has. If you run a shop and have a T250 come in, you need these schematics and torque specs. If you’re a home garage guy who buys used equipment and wants to keep it running without guessing, get this. It’s 1064 pages of factory data. No aftermarket condensation. If you’re used to working on a Manual Transmission vehicle, the T250 hydrostatic system is different – and this manual shows you exactly how it works. The hydraulic schematics are more complex than any Manual Transmission linkage, so you need the real thing.

Source Validity: OEM vs Aftermarket

I trust aftermarket manuals about as far as I can throw a T250. This is a Bobcat-printed Service Manual, dealer copy, not for resale originally. 6902724 (2-06) – that’s the publication number. The PDF is a direct scan of the factory binder. Compare that to a third-party reprint that might have wrong torque values or missing pages. The BICS™ (Bobcat Interlock Control System) wiring is unique – one wrong pinout and you can lock the machine out. This manual has the correct schematics.

FAQ

Does this manual cover the Bob-Tach hydraulic cylinder rebuild?

Yes – see the CYLINDER (POWER BOB-TACH) section: checking, removal and installation, parts identification, disassembly, and assembly. Factory specs included.

What about the BICS™ valve solenoid testing procedure?

It’s in the HYDRAULIC CONTROL VALVE (2 PIECE CASTING) (FOOT CONTROL) section under BICS™ Valve, Solenoid Testing. The manual gives you resistance values and voltage checks. If you don’t have the factory specs, you’ll end up replacing a good solenoid. I’ve seen that happen. The procedure includes removal and installation of the solenoid, disassembly and assembly, and the testing steps. You also get the lift arm by-pass orifice, check valve, and lock valve service for the BICS™ system. So if the machine won’t start or the lift arms won’t lock, you can diagnose it without calling the dealer.

Access the Factory Manual and put it on your shop tablet or print the pages you need. No more guessing – just turn the page and torque it to spec.
