I would not be a bit suprised if your fan does not need replacing. We run a 9190 deutz allis and we have to replace the cooling fan in it almost every 2 years because the dust grinds off the fins and it begins to overheat. I would definately recomend changing the fan on it i think it will help it out a lot! Good luck and if you have any questions my email is brent_56@hotmail.com
