Preface
About the document
Content
The descriptions for maintenance and care of the engine can be found in these
operating instructions.
Work instructions
A prerequisite for proper maintenance is a proper and complete basic tool, as well
as the required devices and special tools.
Use only clean and undamaged tools. Damaged tools must not be re-used; they
must be replaced in good time. Cleanliness and order contribute to safety at the
workplace.
Clean the diesel engine and, here in particular, the connections and screw fittings
of oil, fuel and care products at the start of the repair work. Do not use aggressive
cleaning agents. Use lint-free cleaning rags. Do not use any flammable liquids to
clean the diesel engine.
Sealing materials (e.g. o-rings, seals etc.) are to be replaced.
Parts that are removed are to be checked for reusability and replaced if necessary.
Screw connections are to be tightened according to the standard torques if no
specific torque and tensioning instructions are stated
Spare parts
- Only original LIEBHERR spare parts or spare parts purchased from LIEBHERR may be used for the maintenance of LIEBHERR diesel engines.
- LIEBHERR will cancel all possible obligations received by LIEBHERR and/or its dealers, such as guarantees, service contracts etc., without advance notice if any parts other than original LIEBHERR parts or spare parts purchased from LIEBHERR are used for maintenance.
- All “Part information” in these operating instructions, e.g. ID numbers, thread dimensions, dimensions, etc. are for information only; spare parts may only be ordered using the spare parts catalogue that is part of the scope of delivery.
