Marathon Electric Air Compressor Motor, 5HP is rated 2.0 out of 5 by 3.
Rated 1 out of 5 by from Don't buy !!!!! I bought this motor from the local Tractor Supply on April 21st. installed it and it ran fine until July 6th. when it burned out. The reset was stuck, the tar leaked out of the capacitor and the winding was burned up. Called Tractor Supply and they said I could return it. I just went into town this morning, July 19th. and took the motor with me for return. I then found out since I had purchased a maintenance contract I would have to go through them. They supplied the contact information and I called them. First thing they said was that the maintenance contract did not go into effect until AFTER the mfg. warranty expired. They gave me a number to call. I called and the people said they did not take care of motors only appliances. I called Power Plus Plan back and was given another number to call. After giving them the information on the motor they ask me to send a photo of the motor name plate. Now even though the motor box had a GE id number I received a email saying it was built by Marathon and was given another number to call. I called and was told they did not supply directly to Tractor Supply so I would have to call someone else. The interesting thing here is that Marathon is supposed to warranty the motor for 12 months after installation while my motor was only in service for less than 3 months. In any case I called the last number given and got voice mail and no one has retuned by call. Don't buy one. Is a piece of c--p. Don't waste your money on a extended warranty. It is also c--p. Don't depend on any factory warranty. It is again a piece of c--p. If you want to go through what I have today buy one. If you want something that works buy elsewhere.

Rated 1 out of 5 by from weak capacitor I bought this motor to go on my Ingersoll Rand compressor tha I purchased from Tractor Supply 5 years ago. The first one that I purchase two weeks ago went out within a week. I exchanged it and the second one lasted one day. The capacitors seem to be two weak. If you rain the air tank the motor will start the compressor with no load and then you can build up pressure. but it will not run the compressor with a load already in the tank. will return the second one next week.

what kind of oil we can add if needed and where is the location of oil plug?

Asked by: sam lee
The motor is electric and needs no oil. Also, the bearings are sealed so no lube is needed.

The website says that the list motor is CW rotation only. The nameplate on the motor in the pic shows this motor to be reversable. Which is correct?

Asked by: Kevin1807
We spoke with the manufacturer. The motor rotates both directions. We will correct the error on our website.

The specs indicate clockwise rotation; from which end? Shaft end or other end? How do I change direction if necessary?

Asked by: Sabine
The rotation of the motor is clock wise. The rotation is determined by looking down the motor opposite drive end. IE standing behind motor looking across to shaft end. That would be clock wise. Unfortunately, this motor can not be reversed.
