Kobelco wrote this shop manual for the SK140SRLC short-radius excavator, serial YH06-08001 and up, first edition October 2010. It is the factory's own procedure set, built around the Mechatro control system and the Mitsubishi D04FR engine.
You know the job. The machine goes slow on every function, the multi display shows a code, and the crew stands around while you guess between a sensor, a proportional valve and the pilot pump. This book gives you the error code tables, the trouble-by-symptom charts and the hydraulic and electric circuit diagrams to trace it properly.
It also covers disassembly of the attachment, upper structure, travel system and swing bearing. Buy it once and it stays with this machine for every hour on the meter.
