I decided to replace solenoid after further checking; however this is a very good point for all Bobcat owners to take note of. Bobcat dealer price for this solenoid only(no valve) was $ 304.00; the same part from a Kubota tractor dealer down the road was $ 143.00. Same kubota part for same Kubota engine. I believe people should make a fair profit (and keep in mind that the tractor delaer is making a profit at $143) but Bobcat's profit is radically excessive (actually insulting). Bobcat's additional profit would have been more than the my total cost of the part.
MAY THE BUYER ALWAYS BEWARE!
For kubota parts buy from M G Bryan equipment I believe they are located in Texas, and they ship same day. #972-623-4300 They have always had any part for a Kubota in stock I have ever needed, and they can tell you the torque of any bolt on the engine from memory. They are very good.
