Liebherr D 846 Engine Service Manual

The D 846 is the diesel engine that powers cranes and other heavy machines, so when it's down, the whole machine is down. A service manual is what you reach for when the machine is out of warranty and your shop is doing the repair in-house, or when a used unit shows up with no paperwork. You're trying to pull, rebuild, adjust or diagnose the engine without guessing.

What this manual helps you do

• Diagnose engine faults by working through the malfunctions section.
• Adjust valve clearance following the procedure in the manual.
• Rebuild the cylinder head, valves, cylinder liners and crankcase with the workshop steps.
• Check the fuel system, including the in-line injection pump, injection valves and Fuel Service Center FSC.
• Replace the coolant pump, exhaust turbocharger or EGR module and verify the drive and fan setup.

Who this is for

A crane service technician or rental fleet mechanic who repairs engines in the yard instead of sending them out. It also suits independent repair shops and plant maintenance staff who need a documented procedure for each job.
