Well we keep loosing those crappy little belts on the WOW ovens. Call comes in that the pizzas are not being cooked all the way in the middle. They are PJ six rib belts. They get dried and cracked and start slipping at high RPMS. Am I not aligning them properly, tension? I doubt it. We have found replacements at Mcguire bearing and am wondering if we need to get them from Middleby based on them being engineered for heat stress and variable RPM's. Id appreciate any feedback. Thanks.
