Idler pulley problems
I have an old Roto-Hoe 990 tiller that has an idler pulley with a brass bushing to tension the main drive belt. A couple years ago it was overheating so I replaced the brass bushing. Now it is overheating again. It starts to smoke after using it a while so I shut it off and let it cool down before I continue tilling. Anybody know what I can do to prevent this overheating issue?
