Bobcat T250 2008 Service Manual – Factory Specs for the Compact Track Loader

This is the factory Bobcat T250 2008 Service Manual—not some aftermarket reprint. 965 pages, printed in 2008, sourced directly from Bobcat Company. If you’ve ever fought a hydraulic leak on a T250 because some online forum said to torque the main relief valve to “tighten till it feels right,” you know exactly why this manual matters. I’ve seen guys snap off port relief valves guessing at specs. That mistake costs hours and a new valve block. This manual ends that guesswork.

Safety Instructions: What Fire Prevention Covers

Right in the CONTENTS you get a full Safety Instructions section followed by a dedicated Fire Prevention chapter. It breaks down by system: Maintenance, Operation, Electrical, Hydraulic System, Fueling, Starting, and even Welding And Grinding. Each subsection has specific warnings for the T250. On page 3, the manual spells out: “Never service the loader without instructions.” That’s boilerplate until you need to jump the BICS system to do a remote start. The Fire Prevention section on Electrical tells you exactly where the battery arcs can ignite fuel vapors. If you’re working with biodiesel blends, this manual lists the fuel specifications in the Fuel System chapter—something the aftermarket manuals always skip.

Engine and Electrical Systems: 2008 Coverage

The Engine section runs through the Kubota diesel that lives in these loaders. You get the lubrication system with oil charts, cooling system flush procedures, and the exact coolant capacity. The Electrical portion covers the Bobcat Interlock Control System (BICS)—cab door sensor circuits, remote start tool harnesses (MEL1563 and 6689779 kits), and the loader service tool harness. Need to troubleshoot a no-start? The Remote Start Procedure on page [DATA NEEDED] walks you through using the service tool harness control without bypassing safety circuits. That’s the difference between a shop manual and a Chilton: real factory wiring diagrams, not generic symbols.

Hydraulic System: Schematics and Port Relief Valve Adjustment

Hydraulic/Hydrostatic Schematics are in their own chapter. You get a glossary of hydraulic symbols, troubleshooting flow charts, and then the mechanical breakdowns. Cylinder (Lift) and Cylinder (Tilt) sections include testing, removal, disassembly, and assembly. The Main Relief Valve chapter has a description, testing procedure, adjustment specs, and removal. If you’ve ever wondered why your T250’s auxiliary hydraulics are weak, the Port Relief / Anti‑Cavitation Valve section (listed under Hydraulic Control Valve) tells you exactly which plug to pull and how to measure pressure without blowing a seal. No “simply adjust” nonsense—it gives you the exact pressure setting and the tool you need.

3 Service Intervals You’ll Actually Reference

This manual doesn’t bury the maintenance schedule. The Service Schedule chart is in the Safety and Maintenance chapter, followed by Air Cleaner Service, Engine Cooling System, Fuel System, and Engine Lubrication. Three intervals that save you from a blown hydrostatic drive:
– Hydraulic / Hydrostatic Fluid change: the chart includes fluid type, capacity, and filter part numbers.
– Case Drain Filters: many guys ignore these until the charge pump starves. This manual lists the replacement interval.
– Breather Cap maintenance: a clogged breather causes housing pressure that blows seals. Manual says to clean it every shift.

Each of those procedures includes torque values for drain plugs and filter housings. You can cross‑check the engine oil and hydraulic fluid specs against the Bobcat T250 2006 Service Manual Bobcat T250 2006 Service Manual or the broader Bobcat T250 Service Manual Bobcat T250 Service Manual. If you’re also working on a Bobcat S175, the S175 2008 manual Bobcat S175 2008 Service Manual – OEM Factory Repair Specs shares many of the same hydraulic component procedures.

Source Authenticity: OEM vs Aftermarket Documentation

I’ve been burned by aftermarket manuals that copy a wiring diagram from a 2004 model and slap it on a 2008. The T250 changed its BICS harness and remote start connector in 2008. This PDF is the dealer copy—printed by Bobcat, not scanned from a third‑party. The OCR excerpt shows “Bobcat Company 2008” and “Dealer Copy – Not for Resale.” That means every safety instruction, every torque spec, every hydraulic schematic passed Bobcat’s engineering review. You won’t find a “general compact track loader” diagram here. It’s T250‑specific, VIN range 531811001 and above.

Compare that to a generic manual for a Manual Transmission application that covers everything from a Ford Fiesta to a Dodge Ram—useless for the T250. The T250 doesn’t even have a manual transmission; it’s hydrostatic drive. This factory document is the kind of source that a shop would chain to the toolbox. If you want to learn how a real service manual reads, check a Manual Transmission section from an OEM—that’s the level of detail you get here, but for the T250’s hydrostatic system.

Does This Manual Cover the Fuel System with Biodiesel Data?

Yes. The Fuel System chapter includes a Biodiesel Blend Fuel subsection with specifications for ASTM D7467 blends. It tells you how to fill the tank, change the fuel filter, and remove air from the system. The Engine Lubrication System chapter has an oil chart that lists ambient temperature ranges and recommended viscosity—critical for San Antonio summers where you can cook a 15W‑40 down to sludge if the wrong grade is used.

Can I use this manual to rebuild the Bob‑Tach power linkage?

Yes. The manual covers Bob‑Tach (Power) Inspection and Maintenance, including the hydraulic lines and solenoid controls. It also has the Bob‑Tach cylinder removal and assembly in the Hydraulic System section.

Why does the manual list two different remote start tool kits?

The T250 went through a production change around serial number 531911001. Kit MEL1563 uses an older service tool harness (MEL1565 and MEL1566). Kit 6689779 uses the newer Service Tool (6689778) and separate harnesses (6689747, 6689746). The manual includes the Remote Start Procedure for both, so you can service any T250 from 2008 without guessing which connector to use. This matters because the older harness won’t plug into the newer loader without a pin adapter—and the manual shows exactly which pins cross.

If you plan to own a T250 for more than a year, this manual pays for itself the first time you need to adjust the main relief valve or replace a case drain filter. It’s not a coffee‑table book. It’s a workbench tool. Access the Factory Manual and keep a copy on your tablet or laptop in the shop. You’ll thank me when the loader is down and the service schedule says to check the charge filter before pulling the pump.
