Bobcat 337, 341 2007 Service Manual – OEM Factory Specs

Right off the bat, if you’re cracking open this Bobcat 337, 341 2007 Service Manual without reading the safety section on page 3, you’re asking for trouble. I’ve seen guys skip the fire prevention steps and end up with a shop fire. This factory manual isn’t a suggestion—it’s the exact procedure Bobcat engineers wrote for your G Series machine. 1037 pages, no missing steps, no generic diagrams. That’s what you’re buying.

1037 Pages of Factory Procedures

You get the full index: delivery report, serial number locations, engine serial number, and the complete safety and maintenance schedule. Page 1 shows the serial number ranges (337 S/N 234611001 & Above, 341 S/N 234711001 & Above). If your machine falls outside those, this manual won’t match. Inside, every chapter follows the OEM flow – from air cleaner service to the spark arrestor muffler. The engine lubrication system section tells you oil capacity and filter part numbers. No guessing.

Hydraulic System: Cylinder and Relief Valve Specs

Half the manual is dedicated to the hydraulic system. You get schematics, troubleshooting for the cylinder circuit, slew circuit, and travel circuit. Every cylinder – boom, arm, bucket, blade, clamp – has testing, removal, and assembly steps. The port relief valve adjustment procedure is spelled out with pressure settings. I’ve watched guys burn a weekend resetting a main relief valve because they didn’t have the factory spec. This manual gives you the number. Use it.

Engine and Fuel System Coverage

Fuel system section covers fuel specifications, filling, draining, water removal from the filter, and air bleeding. The engine accessory drive belt adjustment is there with the correct tension. Cooling system cleaning and coolant replacement steps are included. If you’re working on the engine, stop using aftermarket scan data. The factory manual tells you exactly how to remove air from the fuel system after a filter change – a step the aftermarket reprints usually skip.

Does This Manual Cover the Wiring Diagrams?

Yes, the electrical section is built into the safety and hydraulic chapters. You won’t find a separate wiring diagram book, but the troubleshooting sections reference electrical connections for the hydraulic control valve solenoids and the diagnostic couplers. For a full electrical schematic, you need the separate Bobcat electrical manual. This Service Manual focuses on mechanical and hydraulic repairs – which is where 90% of the work lives. The section on fire prevention includes electrical system warnings: keep arcs and sparks away from batteries. That’s practical safety, not just fluff.

7 Major Systems Covered in the Index

Look at the TOC: safety instructions, fire prevention, serial number locations, delivery report, safety and maintenance, hydraulic system, and the detailed cylinder work. Each system has its own procedure with required tool lists implied (you’ll need a torque wrench, micrometer, and pullers for cylinder disassembly). The “Lifting and Blocking the Excavator” section is mandatory reading before you put a wrench on anything. Aftermarket manuals don’t include the correct blocking points – this one does.

Fire Prevention and Safety Protocols

Page 3 has the warning: “Never service or adjust machine with the engine running unless instructed to do so in the manual.” That’s a direct quote. The fire prevention chapter covers fueling, starting, and welding/grinding near painted parts. If you’re welding on the frame, you need the spark arrestor exhaust system info. The manual also tells you to keep tailgate closed except for service. These aren’t suggestions – they’re written into the Bobcat safety standards.

Can I use this manual for the 2008 models?

No. It’s specific to 2007 G Series with the serial numbers on page 1. Later models have different hydraulic pumps.

Why should I pay more for OEM over a PDF from a third-party site?

Because third-party sites sell reprints of reprints. They miss pages, crop diagrams, and often use scans that are unreadable. This is a direct digital capture of the original Bobcat print – 1037 pages, fully searchable, with the same layout Bobcat dealers use. I’ve had a guy bring me a $20 manual that had the wrong torque spec for the boom cylinder bolts. That costs you parts and time. This factory manual gives you the exact spec from the Bobcat engineering team. Access the Factory Manual and don’t waste money on guesswork. For general transmission knowledge, see Manual Transmission but for this excavator, stick to factory. Also check Manual Transmission for basic principles, but your hydraulic system needs this specific manual.

Stop wasting time with aftermarket junk. Access the Factory Manual – the Bobcat 337, 341 2007 Service Manual – and get the right torque values, the correct bleeding procedures, and the wiring callouts that keep your machine running. I’ve built my shop on factory specs. You should too.
