I'm trying to cpmplete a KR-2S started by someone else and have run into a stumbling block.
The Suburu engine runs the generator through a belt drive. There is a second, smaller pulley mounted flush with the generator drive pulley which drives the vacuum pump. This system seems to work, except that the guy who started the plane ground the center of the pulleys down so far that they wobble terribly. I need to replace the two pulleys and can not find anything to replace them with. My first question is: Does anyone know where I can get pulleys like this? They both should have 15mm inner diameter. One is 60mm OD and the other is 100mm OD. Second question: Does anyone have a suggestion for a better system to drive my generator and vacuum pump? I have a quote from a local machine shop to custom fabricate a dual pulley assembly for me for $400, but I'm hoping to avoid that option. Thanks, Kirk Lacewell
