OUTLINES OF SERVICE
CARRYING OUT KOWA (Komatsu Oil Wear Analysis)
The oil clinic samples the oil periodically and analyzes it. This is a preventive maintenance service, which provides
early discovery of abnormal parts and wear of the drive parts of the machine. This then makes it possible to ensure
prevention of failures and reduction in downtime.
Komatsu's long years of experience and rich supply of accumulated data make it possible to accurately determine
the condition of your machine. This enables us to locate the problems and to recommend suitable and timely repair
methods.
The oil clinic charges the customer only the actual costs, and provides an immediate report of the results of the
analysis and recommendations for action to take. This low-cost service can save you high costs and inconvenience
in the future, so we strongly recommend you to avail yourself of this service.
KOWA ANALYSIS ITEMS
Analysis of metal wear particles
This uses an ICP (Inductively Coupled Plasma) analyzer to
measure the density of metal wear particles in the oil.
Measurement of particle quantity
This uses a PQI (Particle Quantifier Index) measurer to
measure the quantity of iron particles of 5µm or more, enabling
early detection of failures.
Others
Measurements are made of items such as the ratio of water or fuel in the oil, and the dynamic viscosity.
