Maybe someone will have an answer. First after seeing the prices of electric motors these days I am still trying to get my heart restarted. The last motor I bought was about 7 or 8 years ago and about $90 for a descent motor. Same basic motor today is like $450. Good grief what happened? And, finding used ones just didn't come up much. Maybe my search powers are weakening.
We have a craftsman compressor 919.186430 that uses a motor labeled as MO-3019-2. Best guess is it was made by GE in the USA probably 10 years ago. I picked up a used newer Craftsman compressor 919.195412 and in comparing the specs the pump, pulley, flywheel and all other componets they are exactly the same as the one I have had for 10 years except that the output is about 2 CFM less. Probably RPM. The motor in my old one is 5 HP and the new one is 1.9 HP. (Yes I know they lie on the HP ratings however I do believe that the old motor is more powerful while the new one is probably more efficient). Anyway, I was trying to find what the actual specs were on the MO-2019-2 motor so I could compare it to the newer compressor which uses a Z-D20620 motor. Any place I try to look up a MO-2019-2 motor it substitutes in a Z-D20620 motor as the replacement so if I had to replace the old motor it looks like I would lose 2 CFM or about 25% of the output. Anyone know the answer to what has gone on in motors or does any one have a really good source for air compressor motors that will cross that 5 HP motor to an equally powerful motor instead of this 1.9 HP motor? Devilbliss made the units for Craftsman before K-Mart stepped in and bought Sears. I am hoping to keep my eyes out for a good used bolt in 120/240 single phase motor that will bring this new compressor up the 25% without going broke. Thanks in advance - Steve
