Not what I am posting about here, just a Kohler Partners website note on short blocks.
Recently I notice per paperwork on a new short block install here that we should looking up short block ipls after we received Kohler engines that had been shorted block per their short block SNs if we are needing internals for the new short block. Well I tried and the current system doesn't allow that. But after emailing Kohler Tech support it is supposed to work; however, not all of the short block SNs have been loaded and that they are working on resolving that issue in the near future. We actually should had been to do the same using the SB pns as a model number but doesn't work currently either.
This is something very important for them to do as they are changing parts in the new short blocks vs the original engine setup. Hopefully they will get this done sooner than later as I personally done ran across two engines with new short blocks. I have been lucky in the sense it has been external problems and not something inside those short blocks so far.
Here is a couple examples of an engine that has been short block should be labeled. One of the ones I came across only had the second serial number label applied.
