4Replacement 5 hp Compressor motor
By william 111
Shipment of motor from provider was very prompt.Motor was an exact model current production replacement for the origional one on my compressor.You have to be sure of your motor rotation and the replacement motor rotation, frame type and shaft size etc.The price was the best I could find anywhere for a good quality non-chinese motor.I had the origional motor for more than 10 years of regular use before failure and then installed a chinese one and it lasted only a coulple of years of light use.The new motor seems fine, starts good runs cool) but I have only used it for a month. Be sure YOUR BREAKER IS NEW and JUST the next size above current rating of motor. The WIRING and OUTLET sized for 50 percent more than breaker rating.)This gives you FAST STARTING, COOL RUNNING and quick breaker protection in case of voltage drops or spikes!!!!!!!I AM VERY SATISFIED AT THIS TIME.!!!!!!!!!!!!!

5Good quality at a reasonable price
By PR2000
I burned up the 5 horsepower motor on my compressor after about 15 years of use due to normal wear. I purchased this motor as a replacement. The motor bolted right into place and all electrical connections wear easily made up. The motor works great and I suspect is good for another 15 or 20 years.

5Horses are there
By Sergei
5 Horse Power looks like its there. Not too sure about the ball bearing the instruction states its got sleeve bearing. So I'm confused a bit now. Other than that the motor is great.
