Grove 3340B and YB4411 Rough Terrain Crane Service Manual

A rough terrain crane like the Grove 3340B or YB4411 works on uneven, unpaved job sites, setting up on outriggers and lifting with a telescopic boom from a single cab. When one comes into the shop for repair, the person holding the wrench needs a workshop document, not a spec sheet. That's usually a crane service technician or fleet mechanic fixing a machine in-house, or working on a used crane that arrived with no paperwork.

What this manual helps you do

• Troubleshoot faults using the Troubleshooting Guides section before you start swapping parts.
• Check relief valve settings by following the Relief Valve Pressure Check procedures.
• Rebuild the front drive axle and the parking brake using the Front Drive Axle Repair and Parking Brake Repair sections.
• Trace the starting circuit, instrument and light circuits and main electrical system when a wiring problem shows up.
• Follow the scheduled maintenance intervals and the engine oil and fuel type guidance to keep the machine on a proper service routine.

Who this is for

A rental fleet mechanic, independent repair shop or dealer technician who has a 3340B or YB4411 on the floor and needs repair procedures in front of them. It also suits plant maintenance staff who run these cranes and fix them on site.

FAQ

Q: What do I receive and how is it organised?

A: You get one PDF file of 438 pages, in English, with a text layer so you can search and copy text. Sections run from General and Scheduled Maintenance through the brake system, electrical circuits, winch, wire rope and structural.

Q: Which machine does it fit?

A: It's the 3340B/YB4411 Service Manual, publication number CTRL086-01. If your crane is one of those two models, this is the document to open.

Q: How does it fit the job I'm doing?

A: If you're pulling a component, setting pressures or chasing a fault, the Component Repair, Testing and Troubleshooting Guides sections give you the procedures. The hydraulic fitting F.F.F.T. method (flats from finger tight) is in there too, for reassembly.

Search the PDF for the part of the crane you're working on and you can go straight to the procedure at the bench or beside the machine.
