Bobcat T320 2008 Service Manual – OEM Factory Repair Specs for Skid Steer Loader

Mike Callahan here. I’ve spent 28 years turning wrenches in San Antonio, and I can tell you this: if you’re trying to rebuild a Bobcat T320 2008 Service Manual without the actual factory book, you’re going to blow hours and break parts. I’ve seen guys throw a reman hydrostatic pump into a T320 using aftermarket torque values from a third-party website. Charge pressure was off by 150 psi. Seals blew. That’s a $2,800 mistake. The factory manual gives you the exact procedures, the exact specs, and the exact safety warnings that keep you alive. This 940-page OEM document from Bobcat is what the dealer techs use. It’s what I use when I’ve got a T320 up on the stands.

Safety Instructions and Fire Prevention – Built Into Every Procedure

Page 3 of this manual hits you with the safety instructions before you even get to a single torque spec. Bobcat doesn’t bury this stuff. They cover fire prevention during maintenance, operation, electrical work, hydraulic system service, fueling, starting, and even welding. The spark arrestor exhaust system gets its own section. If you’re welding or grinding painted parts, the manual tells you to wear a dust mask and ventilate. That’s the kind of detail that keeps your shop from burning down. The manual also calls out the Bobcat Interlock Control System (BICS) right on the cover – page 1. That system can lock you out of controls if you skip steps.

Engine Cooling and Lubrication: OEM Service Intervals

The ENGINE COOLING SYSTEM section walks you through cleaning the radiator, checking coolant level, and removing/replacing coolant. No generic “flush every year” – they give you the exact fill procedure and capacity. The ENGINE LUBRICATION SYSTEM includes an oil chart with API specs and viscosity grades for your climate. It covers removing and replacing the oil and filter. You don’t guess at drain plug torque. The manual lists it. Aftermarket manuals leave that out and you end up with stripped threads.

Hydraulic/Hydrostatic System – 7 Subsections of Rebuild Data

This is where the manual earns its keep. The HYDRAULIC/HYDROSTATIC SYSTEM sections cover the lift cylinder, tilt cylinder, and Bob-Tach cylinder – each with testing, removal and installation, parts identification, disassembly, and assembly procedures. The main relief valve gets a dedicated description, testing, adjusting, and removal. The hydraulic control valve section runs over ten pages of spool removal, solenoid removal, lock valve removal, load check valve removal, and anti-cavitation valve work. If you need to tear down the valve stack, this is the only source that shows you the correct order and O-ring placement. The manual also includes charge filter removal and replacement – a common failure point on T320s. Trust me, you do not want to guess which port relief valve goes where.

3 Critical Maintenance Sections You Need to Follow

Air cleaner service – replacing filter elements. Fuel system – including biodiesel blend fuel specifications, filling, filter, and air removal. Spark arrestor muffler – cleaning procedure. These are the items that cause downtime if ignored. The manual includes the SERVICE SCHEDULE chart, so you can plan your intervals. No fluff, just the chart with hours and actions.

Does This Manual Cover the Electrical System?

Yes. The fire prevention section explicitly covers electrical safety. The manual also details the remote start tool kits (MEL1563 and 6689779) with harness part numbers and remote start procedures. The operator cab section includes cab door sensor adjustment. For the BICS system, the wiring and control logic are referenced throughout. If you’re chasing an electrical fault on a T320, this manual gives you the starting point. The full hydraulic/hydrostatic schematics are included, and I’d recommend pairing this with the electrical schematic manual if you’re deep into a harness repair.

Frequently Asked Questions

Is this manual a reprint or a copy?

It’s the original OEM PDF from Bobcat. 940 pages, full text searchable. No missing pages. No watermarks.

What torque values are included?

The manual lists torque specs for cylinder base end pivot pins, port relief valves, and many fasteners. You need the exact foot-pound values for hydraulic fittings and engine components. Those are listed in the service procedures alongside the step-by-step instructions. I’m not going to list them here because you need the manual context to know which procedure uses which torque value. One wrong torque on a hydraulic line can cause leaks or worse. The manual also includes the correct tightening sequences for multi-bolt flanges. That is something aftermarket manuals often skip.

How long does it take to download?

It’s a 940-page PDF. With a good connection, under 2 minutes. Immediate access after purchase.

Can I print this manual?

Yes. The PDF is not encrypted. You can print sections as needed. I recommend printing the safety pages and laminating them for the shop wall. But be smart about it – printing the whole 940 pages will use a ton of ink. Only print what you need for the job at hand. The searchable digital version is faster for finding specs on the fly. I keep a tablet in the bay. That works better than paper because you can zoom into the diagram. And if you spill hydraulic fluid on the tablet, you still have the file. I’ve done it – the file survived, the tablet didn’t. So yes, print what you need, but rely on the digital copy for the heavy lifting.

So stop guessing. Stop relying on third-party data that costs you money and time. Download the Factory Manual and get the real specs that keep your Bobcat T320 running and your body intact.
