How do you find the year built and model of a Caterpillar 931 Serial number 78U2340? Thanks Donald
You sure about the SN ?
SIS says SN not found
SIS often does return the " SN not found" for the older machines if you are looking for the "As Built" information.
But if you enter that SN in the "https://www.servicemanualpro.com/" for instance they list a whole range of manuals for that SN.
For all the limitations of SIS one does have to give Cat credit for what they make available on SIS! Try to get information on some equipment from other companies that is say 10 years old and it can be almost impossible!If you just put 78U in SIS it will offer you two options, above and below a certain S/N. No info regarding build date and options is available in SIS for machines of that era.
