Bobcat 320C 2006 Training Manual – Factory Specs, Electrical Diagnostics & Safety

If you’re working on a Bobcat 320C excavator and you don’t have the factory training manual, you’re guessing. Guessing on a hydrostatic drive system or an electronic monitor setup gets you a torn-down machine and a phone call to the parts counter. This 99-page Bobcat 320C 2006 Training Manual is the same binder used in the factory technician course. It’s not a reprint. It’s the original student manual from May of 2006, prepared by Jorge Gorritti Rey. You get the exact procedures that Bobcat certified techs follow – electrical schematics, sensor testing labs, and engine timing data. No aftermarket interpretation.

This manual breaks down into three major modules, each packed with lab exercises and reference sheets. Page 13 kicks off with safety – daily inspection points, lockout procedures, and hydraulic system hazards. Page 26 drops you into the electrical schematic usage and sensor fault location. The rest of the document is a stepwise walk through the 3066 engine systems, fuel delivery, and monitor diagnostics. Everything is written for the guy who needs to get the machine running and then teach someone else how to do it.

Before you crack the cover, check out the related manuals for other Bobcat models: Bobcat Barredora con Cajón Colector 1997 User Manual – OEM Factory Specs, Bobcat 54, 60, 72 2002 User Manual – OEM Factory Specs, and Bobcat 2200D 2005 User Manual – Factory Operation & Maintenance. Each one follows the same factory spec format.

Module 1: Excavator Familiarization and Safety Procedures

Module 1 runs from page 9 to 22 and covers the basics: machine specifications (dimensions, weight, capacities), daily maintenance checks, service point locations, cab controls, and safe operation. The safety sheet on page 13 is worth the price alone – it lists specific pressure relief procedures and lockout points. Most DIY guys skip this and end up with a hydraulic oil bath. If you’re teaching a new operator, the control identification section (Lección 1.5) puts every lever and switch in context. Don’t skip the daily maintenance sheet – it shows you which fittings to grease and where the hidden drain plugs live.

Module 2: Electrical, Electronic, and Monitor Systems – What You Need to Diagnose

This is where the training manual separates itself from a generic repair guide. Module 2 covers the electrical schematic reading, starting and charging system evaluation, sensor testing, relay evaluation, and the full monitor system diagnosis. The labs are real: you get a wiring diagram, a voltmeter, and a step-by-step to find a bad sensor without guessing. Lección 2.2 dives into the electronic control system – how the ECM communicates with the monitor, fault codes, and override procedures. If you’ve ever had a 320C that won’t start and the monitor says nothing, the troubleshooting logic here will save you a weekend. The factory lab for evaluating a relay (Lab 2.4) is something most aftermarket books don’t even mention.

Module 3: Engine Systems – The 3066 Diesel Engine

The 3066 engine gets its own module. Lección 3.1 breaks down the major systems: intake/exhaust, lubrication, cooling, and electrical. There’s a worksheet for component identification and another for system interaction. Lección 3.2 covers the fuel system from tank to injector – no fuel return line is left undocumented. The manual also includes a reference document for sensor fault location using the electrical schematic. If you need to pull the head or adjust the injection timing, the factory procedure is in here. None of that “tighten until snug” nonsense – Bobcat specifies torque values in lb-ft, and this manual lists them for every critical fastener.

Who Needs a Factory Training Manual for the Bobcat 320C?

If you own a 320C and do your own maintenance, this manual moves you from part-swapper to diagnostician. If you run a shop that repairs these excavators, the training manual is the reference your techs should read before they touch a customer machine. Operators who want to understand why the machine behaves a certain way will find the monitor system logic and electronic controls explained in plain terms. Even if you’re a beginner, the lab exercises walk you through the tests with required tool lists – you’ll need a multimeter, a pressure gauge, and a scan tool to follow along. The manual doesn’t assume you know the machine, but it also doesn’t waste time rehashing basic wrenching.

OEM Training Manual vs. Aftermarket – Why This One Wins

Aftermarket manuals copy from a service manual written for a different machine and hope it fits. This Bobcat 320C 2006 Training Manual is the actual document used in the factory instructor-led course. The wiring diagrams are model-specific. The lab steps match the actual training bench setup at the Bobcat facility. I’ve seen too many “universal” manuals that skip the safety lockout procedure or give the wrong fuel pressure spec. This manual doesn’t have that problem because it came from the manufacturer. The only downside? It’s 99 pages of dense technical content – not a quick read. But when you’re bleeding a fuel system or chasing an electrical fault, the page you need is in there.

And if you’re unsure about reading electrical schematics, the Manual Transmission article covers the fundamentals of circuit tracing.

Frequently Asked Questions

Does this manual cover the 320C’s emissions system?

No. This is a 2006 training manual, pre-Tier 4 emissions. It covers the mechanical fuel injection and basic engine controls. For emissions systems, you’d need a later service manual.

How many pages is the Bobcat 320C 2006 Training Manual?

99 pages. Three modules plus appendix with literature references and tool lists.

Can I use this manual if I only have basic mechanical experience?

You can, but you will need a multimeter and a basic understanding of diesel engines. The lab exercises assume you know how to test voltage and continuity. If you don’t have that, start with the electrical schematic reading lab on page 26 and work through it slowly. The safety sheet on page 13 is mandatory reading before you attempt any live machine work.

What tool list is included in the manual?

Pages 6-7 list required literature and necessary tools: multimeter, pressure gauge, scan tool (Cat ET or equivalent), and basic hand tools. No part numbers – just functional requirements.

If you’re tired of flipping through generic PDFs that don’t match your machine, get the real thing. Access the Factory Manual and start working with specs that a Bobcat engineer actually signed off on. Your 320C will thank you, and your wallet won’t hurt as much.
