Bobcat 337, 341 2007 Service Manual

If you’ve ever tried to rebuild a hydraulic pump with generic specs, you know the drill – stripped threads, wrong clearances, and a machine that won’t hold pressure. That’s why the Bobcat 337, 341 2007 Service Manual exists. At 1037 pages, it’s the factory-authorized document that tells you exactly how to disassemble, inspect, and reassemble every system on these compact excavators. No interpretation. No third-party shortcuts. Just Bobcat’s own procedures.

Bobcat 337, 341 2007 Service Manual: What This Covers

This manual is split into two major sections: Safety and Maintenance (covering everything from lifting procedures to the cooling system) and the Hydraulic System section. Under Hydraulics, you’ll find complete schematics, troubleshooting charts for cylinder, slew, and travel circuits, plus disassembly and assembly instructions for each cylinder – boom, arm, bucket, blade, clamp, and boom swing. The hydraulic pump section includes a pump work sheet, torque limiter adjustment, and initial setting procedure. Every fastener spec is OEM factory data.

Start With the Safety Section

Page 1 opens with a blunt warning: “Never service the Bobcat Compact Excavator without instructions.” That’s not CYA – it’s reality. The fire prevention section covers welding, grinding, and fueling precautions. If you plan to weld on the frame, read the electrical and welding guidelines first. The manual also shows serial number locations for both the excavator and engine (page 2), so you know exactly which revision you’re working with. Skip this and you risk an expensive mistake.

Does This Manual Include Torque Specs?

Yes. Every major fastener – cylinder rod ends, hydraulic pump couplers, relief valve adjustments – lists the specific torque values in foot-pounds. The manual uses imperial units throughout, which matches North American shop tools. You won’t find metric-to-imperial conversions that add confusion; it’s all ft-lb where required.

7 Hydraulic Troubleshooting Sections

The Hydraulic System Information chapter alone has troubleshooting procedures for the hydraulic circuit, cylinder circuit, upperstructure slew circuit, and travel circuit. Each is broken down by symptom, cause, and corrective action. If your 337 or 341 won’t slew smoothly, you turn to that subsection and get a step‑by‑step diagnostic. The glossary of hydraulic/hydrostatic symbols helps you read the schematics without guessing.

Engine and Electrical: Factory Data

The engine lubrication system section covers oil charts, replacement intervals, and filter specs. The electrical fire prevention subsection in safety stresses the importance of disconnecting the battery and grounding before any electrical work. You also get the alternator and starter wiring details in the schematics. For the complete wiring diagrams, you’ll need to reference the hydraulic schematics section – the manual integrates electrical and hydraulic diagrams to show how the engine drives the pump.

FAQ

Does this manual cover both the 337 and 341 models from 2007?

Yes, it covers both models for S/N 234611001 & Above (337) and 234711001 & Above (341), published in 2007.

What specific torque values are included?

The manual includes torque specifications for cylinder rod ends, hydraulic pump couplers, relief valve adjustments, main relief valve settings, and port relief valve adjustments. Additionally, all fastener torques for the hydraulic control valve assembly (inlet, boom, arm, bucket, blade, slew, auxiliary, and travel sections) are given in foot‑pounds. The hydraulic pump section contains torque limiter adjustment values and initial setting procedures. Every value comes from Bobcat’s factory engineering data – not aftermarket reprints.
