FOREWORD:
This shop manual is published for the information and guidance of the
service personnel who repair or rebuild KOMATSU engines and units used
thereon. The manual contains information on the overhauling procedure
as well as description of adjusting and testing methods necessitated
during overhaul operation. All the KOMATSU engine models are included
in this manual because the operational procedures are the same of very
similar, and because the various KOMATSU machines equipped with these
engines are often handled in the same workshop.
It is hoped that the descriptions in this manual are useful to ensure the
right and economical service operation.
