Hi, ETD66SS.
I don't know of an Komatsu-specific forums and the only one I know of where you might get some answers would be Heavy Equipment Forums. Here is a link to a Komatsu page on their site:

I personally have run several Komatsu products, dozers, excavators, track loaders and a largish grader, none for more than a couple of months - all good to operate and reasonably efficient. The main complaints, at least DowNunda, seemed to be parts availability and that they seemed to have about 2/3 the working life to first rebuild and between subsequent rebuilds that a similar Cat had in the same work.
Just my 0.02.
"i reject your reality and substitute my own" - adam savage. i suspect my final words maybe "well shit, that didnt work"
instead of perfection some times we just have to accept practicality
