Does anyone know if an overhaul kit is available for the old York compressors on the 6 cylinder 280's? Mine makes an occasional squeaking sound when undercharged, and will seem to squeal and seize with a proper charge of R12. Aside from that, it runs very roughly. I think it's about shot, and needs a rebuild. I've seen similar rebuilt Yorks on Ebay, and I was wondering if there is an overhaul kit available. Otherwise I could buy a new compressor from Adsit.
