Description
Yanmar 3TNM68 3TNM72 Service Manual is the factory publication for servicing and repairing Yanmar TNM Series indirect-injection industrial diesel engines. It covers the 3TNM68 and 3TNM72 engine models and is written primarily for professional service technicians, authorised distributors and dealer workshops.
This 280-page manual provides workshop information organised into dedicated service sections. It is intended to support accurate and safe engine maintenance, inspection, diagnosis and repair. Directions are based on a typical engine, so specifications and fitted components may vary where an engine installation incorporates optional equipment.
The publication applies to industrial engines certified by the US EPA, California ARB and/or the 97/68/EC Directive. Equipment-specific instructions for the host machine or optional components should be taken from the relevant equipment manufacturer’s documentation.
