yesterday was going along and was hearing noise from my usually humming deck; also noticed the cut wasn't near as good so I pulled it up to the truck and took the deck lid off (MAN was it HOT) and upon inspecting my pulleys realized that one of them(trim side of deck) was loose so I removed the belt (did I mention how HOT everything was under there) and the pulley came right off; the teeth inside it had stripped. So I know I need to replace the pulley but I was also wondering if these ever get greased. My dealer says no but it just seems entirely too hot in there. As well I think the reason the pulley stripped in the first place was due to the blade bolt's nut not being on quite right (somehow I slightly stripped the top threads of the bolt when changing blades recently) So I am going to replace both the bolt and nut as well but sure would like to reduce the heat in there. Any ideas?
