I have a Kubota V2003t engine and im looking for valve specs and adjustment procedure .
You might try the orange tractor talks forum, them guys know their stuff pretty good. Most kboters I've worked on, I think both valves are 7 thousanths, or so, again IIRR. Might be 7 mil, or whatever the metric equivalent is, just remember the number 7 on the feeler gauge! As to procedure, its pretty simple, just roll the motor over, till both valves on a cyl are loose, you might have to do it once per cylinder, if you don't know the actual service procedure, to do more than 1 cyl at a time. http://www.orangetractortalks.com/forums/
