I wish Kubota would release an official service bulletin regarding the 3010 valve replacement for the 3ph, since I'll have mine changed in approx 40 hours.
Doing some reading on this board, it's apparent that not all of the dealers are knowledgable about all of the steps involved in replacing that valve (for example, they have to make an adjustment after valve replacement so that you still get maximum lift height).
A service bulletin with the steps listed out could help prevent little problems like this.
