Liebherr R 944 B Excavator Service Manual

The Liebherr R 944 B is a tracked hydraulic excavator that digs, loads and moves material on construction, quarry and earthmoving jobs. When one comes into the shop with a failed swing gear, a weak hydraulic circuit or a dead electrical function, the technician needs the workshop procedures before anything gets unbolted. That's what this service manual is for. It's the book you open to repair the machine in-house instead of guessing.

What this manual helps you do

• Troubleshoot hydraulic system faults using the hydraulic system and hydraulic components sections.
• Replace or rebuild the swing gear and swing ring with the procedures laid out for them.
• Service the travel gear and track components, from removal through reassembly.
• Check the electrical system and work through the engine and coupling splitterbox sections.
• Verify what special tools a job calls for before you start, using the special tools section.

Who this is for

This is for the dealer technician, the independent repair shop or the rental fleet mechanic who is working on an R 944 B past its warranty. It also suits plant maintenance staff who run their own machines and do their own repairs. The manual covers the R 900 B as well.
