Hello, I'm trying to figure out how the front seal on a York 206 series prevents refrigerant from leaking out, or is it just a dust shield.

My problem is I believe I'm leaking refrigerant at the shaft seal. I removed the clutch to gain access to the shaft cover. The seal had failed, but I can't understand how a new seal will contain the refrigerant. Both original and new seal are not large enough to seal against the compressor housing. The seal fits the shaft fine, but outer circumference does not even come close to sealing at the housing.

My thinking tells me the reed valve assemblies within the valve plate is the true sealing for this compressor and it may have failed.

Something else that's odd. I added dye to the system when serviced. When I removed the shaft cover, I see no trace of dye around the bearing area.

Thank you, Dwight [York 206 service manual] [York 206 A/C Compressor] [Broken front seal] [Replacement Seal] [Front seal York Compressor] [Front Seal]
