Have inherited a diabolical mess of Yorks and have to get filter sizes, belt, and all the normal stuff to limp along these units. I'm a small size guy so when they are up high on a curb I can't get the door panels off without pulling my back almost out! Filter and Belt size would make my day! I can then get some big guys for replacing filters and belts. I will finish dialing them in. Thanks I need this favor please.
