With the objective of maximizing your generator sets performance, Hewitt has created a preventive maintenance program which will help you better prevent and plan, before breakdowns occur. 
 
Thanks to this preventive maintenance program, you can devote your time to your priorities, without having to worry about your equipment maintenance. 

Our service trucks are equipped with diagnostic tools (electronic and mechanical) and all Caterpillar tools, maintenance manuals and measuring instruments, enabling us to facilitate and accelerate the diagnosis of abnormalities and quickly do the necessary repairs. 

Diagnostic Tools
Caterpillar is the undisputed top brand in the field of diagnostic systems which assist technicians in quickly determining the source of a problem and the repairs to be done.

Our electro-technicians work with special electronic tools connected to manometers, on-board computer terminals and programmable automatons which now make up an integral part of a large number of Caterpillar engines.
 
A quicker and more precise diagnosis of breakdowns leads to faster repairs and less downtime. 

Tools and Technical Data
Highly specialized automated diagnostic tools accelerate repairs in our workshop or on your premises, and include portable test benches for tests up to 4000 kW.
 
In addition to electronic communication equipment connected to Caterpillar offices and plants, each of our branches has a complete technical data library of Caterpillar engines which enables them to know more about product changes and improvements effected over the years.
