I read your response, I already know that the rebuild kit is expensive, I asked to know where I can buy the rebuild kit, an 18 hp Onan is an 18 hp Onan engine whether it is in a JD or whatever it is installed in, I will ask again, Where can I buy a 18 Hp Onan rebuild kit, there has to be one somewhere, these engines was manufactured for years, there has to be at least rings , rod , bearings, gasket's, etc. somewhere ?????
Thanks, XXXXX XXXXX
