Working on a Manco 606 and the Torque convertor clutch belt keeps breaking. I lubed most of the convertor and that seemed to help, but it seems like it shreads it after about 10-20 hours if not sooner. Since this kart is primarilly off-road use (easy off road not extream) should I concider changing this over to a direct drive with a centrifical cluch, or is there something else that I should know? I have never delt with a tcc unit and understand the basic principals of it, but would like to know more.
