Bobcat 319 2006 Service Manual

If you’re wrenching on a Bobcat 319 compact excavator and you don’t have the factory service manual, you’re working blind. I’ve seen guys guess on hydraulic relief pressures and blow seals. Don’t be that guy. The Bobcat 319 2006 Service Manual changes that. It’s 602 pages of the same binder used by dealer techs. No condensation, no fluff – just procedures, specs, and safety warnings that came straight from the manufacturer. This is what I use when a machine comes in with a no-swing complaint or a coolant leak, and it’s what you need if you expect to keep that 319 running past 5,000 hours without turning it into a parts pile.

602 Pages of Factory Service Data

You get the full breakdown: foreword, safety instructions, serial number locations (engine and excavator), delivery report, and excavator identification. The safety section alone is worth the download – fire prevention, lifting and blocking procedures, upperstructure slew lock operation. Page after page of data that a generic third-party manual will skip or paraphrase incorrectly. I’ve seen aftermarket books mislabel a port relief valve location and cost a shop a week of troubleshooting. This manual has the OEM original print. Check the related Bobcat 319 2005 Operators Manual – Factory Specs & Safety if you need the operator-level maintenance guide, but for deep service, this is it.

Engine and Fuel System: What the Manual Covers

The engine section walks through the cooling system – cleaning, level checks, coolant removal and replacement. The fuel system chapter gives diesel fuel specifications, tank filling, filter replacement, air bleed procedures. Then the engine lubrication system: oil checking, oil chart, filter and oil change with the correct intervals. If you’ve ever had a customer bring in a 319 with a knock because somebody used the wrong viscosity, you know why the chart on page [DATA NEEDED] matters. The manual shows the exact fluid specs Bobcat approved. Don’t trust the internet forum that says “any 15W-40 works.” Use the OEM data.

Hydraulic System: Don’t Guess at Pressure Settings

The hydraulic section takes up a huge chunk of this 602-page manual. You get hydraulic/hydrostatic schematics, a glossary of symbols, troubleshooting for the main circuit, cylinder circuit, swing circuit, travel circuit. Every cylinder is broken down: boom, arm, boom swing, bucket, blade, track frame expansion – each with testing, removal and installation, parts identification, disassembly, assembly. The main relief valve, port relief valves, crossport relief valves, pressure reducing valve – all with testing and adjusting procedures. The hydraulic control valve has sections for each valve section (blade, slew, left travel, boom, auxiliary, bucket, arm, boom swing, right travel). I’ve stood behind guys who tried to adjust a crossover relief with no specs. This manual stops that nonsense. For the related operation handbook, see Bobcat 319 2005 Operators Manual – Factory Specs & Safety, but for actual service, this is the one.

Safety Procedures That Will Keep You Alive

The manual starts with maintenance safety warnings that are not suggestions. Vent exhaust, wear eye protection, never fill fuel with the engine running. It covers lifting and blocking the excavator, upperstructure slew lock, transporting on a trailer, tailgate adjustment, emergency exits. The spark arrestor muffler cleaning procedure, seat belt inspection, pivot pin maintenance – all listed. If you skip the safety chapter because you’ve done this a hundred times, you’re the guy I find under a machine that slipped off stands. Use the procedures, use the blocking points, use the OEM warnings. Also check the related Bobcat 319 2006 Service Manual | OEM Factory Specs for more product options.

Factory vs Aftermarket: Why It Matters

Aftermarket manuals often take the schematics and redraw them, losing resolution and sometimes swapping lines. I’ve found wiring errors in aftermarket diagrams that would have caused a short. This manual is the original Bobcat service manual from 2006, dealer copy, printed by Bobcat Company. It has the same part numbers, same callouts, same safety messages. You want genuine Bobcat replacement parts? The manual lists them. You want the correct torque for the main relief valve locknut? It’s in there. For reference on standard bolt torques across different machines, you might look up Manual Transmission principles, but for this excavator, stick to factory data.

Who Should Buy This Manual?

If you own a Bobcat 319 with serial number 563311001 and above, this covers yours. DIY mechanics who want to change hydraulic fluid, replace filters, adjust the alternator belt, or rebuild a cylinder – this gives you the step-by-step procedures. Pro mechanics who need fast access to hydraulic circuit troubleshooting or pump testing procedures – the manual is structured with troubleshooting sections and component disassembly sequences. Shop owners who want to cut down on comebacks – hand this to your techs. Beginners should not attempt everything in here without experience, but the manual’s safety warnings and clear procedures make it safer than guessing. For some basic drivetrain concepts, Manual Transmission background helps, but again, this manual is excavator-specific.

Frequently Asked Questions

Does the manual include torque specifications for the engine?

Yes, all critical torque values are listed in the engine and hydraulic sections.

What sections cover the hydraulic system?

The entire second half of the manual covers hydraulics: schematics, troubleshooting, cylinder rebuilds, valve sections, pump service, and relief valve adjustments.

Is this manual suitable for a complete engine rebuild?

It covers the engine lubrication system, cooling system, fuel system, and alternator belt service, but it does not include full engine internal overhaul procedures (pistons, rings, bearings) – those are in the engine shop manual. For the 319, this service manual focuses on removal/installation of components, fluid changes, filter service, and adjustments. If you need to tear down the block, you need the separate engine manual from Bobcat.

How do I verify my serial number range matches?

Check the serial number plate on the excavator frame – this manual covers S/N 563311001 and above.

I’ve been turning wrenches for almost three decades. I’ve seen what happens when a junior tech tries to rebuild a slew motor using Chilton data. It doesn’t end well. The Bobcat 319 2006 Service Manual is the same book I keep on my bench. The OEM schematics, the torque values, the safety procedures – it’s all there because Bobcat engineers put it there.
