Bobcat T320 2008 Service Manual

You’ve got a T320 that’s down. Maybe it won’t start, maybe the hydraulics are weak, or maybe you’re staring at a fuel system full of air. You need the factory procedure, not a Chilton’s guess. Bobcat T320 2008 Service Manual is the only way to get the correct torque values, the right bleed procedures, and the safety warnings that keep you alive. Page 1 alone carries a warning about never working under raised lift arms without an approved support device. That page sets the tone for the entire 934 pages — every step matters, and skipping any can get you hurt or blow a seal.

I’ve torqued enough head bolts to know that aftermarket manuals swap specs between years or flat-out guess on hydraulic pressures. This one is from the factory floor. OEM documentation means you aren’t chasing phantom problems caused by a wrong o-ring size or a misprinted relief valve setting.

Engine Lubrication and Fuel System Procedures

The manual dedicates full chapters to the engine lubrication system and fuel system. You get checking and adding engine oil, oil and filter removal and replacement, and an Engine Oil Chart with capacities. On the fuel side, it covers fuel specifications, biodiesel blends, filling procedure, fuel filter service, and removing air from the fuel system. That last one is a common frustration on T320s that won’t restart after running dry — the manual gives the exact bleed sequence instead of generic steps.

Why Does the Manual Dedicate 934 Pages to Safety?

Look at the table of contents: Fire Prevention sections covering Maintenance, Operation, Electrical, Hydraulic System, Fueling, Starting, Spark Arrestor Exhaust System, Welding And Grinding, and Fire Extinguishers. Each of those has specific guidelines a home garage guy wouldn’t think of. For example, the Electrical subsection warns against using jump-start leads that allow sparks near the battery. The Hydraulic System subsection tells you to relieve pressure before loosening any fitting. These aren’t boilerplate — they’re written for the specific T320 setup.

That’s the whole point of a factory manual.

Hydraulic System: Cylinder Overhaul and Valve Adjustments

The Hydraulic System section covers lift cylinder, tilt cylinder, and Bob-Tach cylinder testing, removal, disassembly, and assembly. Each comes with parts identification and required tool lists. The main relief valve section includes description, testing, adjusting, and removal/installation. The hydraulic control valve (standard) goes deep — lift load check valve, anti-cavitation valve, port relief valve, spool removal, and solenoid removal. If you’ve ever had a lift arm drift or a tilt cylinder that chatters, this is where you find the factory fix. The hydraulic / hydrostatic schematics and glossary of symbols will save you from chasing the wrong circuit.

Use the OEM Torque Specs for Every Fastener

Torque specifications are scattered throughout the manual, not collected in one table. That’s by design — each procedure lists the exact torque at the step where you need it. For example, the cylinder assembly instructions include cap bolt torque values. You won’t find a generic “tighten to 250 ft-lbs” guess. These are the same specs the Bobcat dealer uses. Using aftermarket torque charts is a fast way to strip threads on a track loader that lives under heavy loads.

3 Remote Start Tool Kits Covered

The manual includes two remote start tool kit sections: MEL1563 and 6689779. Each covers the remote start tool, service tool harness control/communicator, and remote start procedure. If the T320’s interlock control system (BICS) locks you out, these procedures let you bypass and diagnose without tearing into the harness. The wiring and harness part numbers are listed — no guessing which adapter you need.

For other Bobcat models, the Bobcat T320 2008 Service Manual (that’s this one) is the standard, but the Bobcat S175 2008 Service Manual – OEM Factory Repair Specs and Bobcat S185 2008 Service Manual – 998 Pages of Factory Specs follow the same structure. Unlike a vehicle with a Manual Transmission, the T320 uses a hydrostatic drive system that requires different diagnostic procedures. If you are used to working on Manual Transmission equipped cars, be prepared to learn new systems — the manual teaches you from the factory baseline.

Frequently Asked Questions

Does this manual include wiring diagrams?

No. The manual covers electrical system safety and component testing but does not include full wiring harness diagrams. Those are in the electrical schematic supplement.

What hydraulic system information does it cover?

Detailed procedures for lift and tilt cylinder disassembly, main relief valve testing and adjustment, hydraulic control valve spool removal and installation, hydraulic schematics, and troubleshooting. The manual includes step-by-step instructions with part identification and required tool lists for each procedure. You also get port relief valve adjustments, anti-cavitation valve service, and Bob-Tach cylinder rebuilds. All with torque specs at the point of use.

The decision is straightforward: you can either guess and risk a blown hydrostatic pump or bent lift arm, or you can access the factory manual and know every bolt is torqued to Bobcat’s spec. Access the Factory Manual — it’s the only source that matches the machine sitting in your shop.
