I want to thank mtr for their expertise on repairing air compressors . my 1966 speedaire compressor is now as good as new. I did spend some cash but it was well worth it. the videos on parts and the explanations were a great help. in my case the compressor was purchased at a recycling station for 5$ no one wanted to mess with it I guess. the safety valve was before the non existant check valve , not at the pressure switch (there was no pressure switch when I purchased it ) the oil hadn't been changed in the pump . the old Westinghouse motor had no schematic for wiring it correctly. so a new motor a new pressure switch , a new check valve with the unloader line , a few other fittings for tank attachments and its as good as new ... if it wasn't for mtr I wouldn't even have know what any of these parts names were so AGAIN THANK YOU MTR ....
