NO Lubrication available!
They have 'Sealed' bearings.
So if the motor is loud, they (bearings) either need to be replaced, or the motor needs replaced.

SOURCE: How to manually reset an AO Smith 2 hp motor?

If you did not press a reset ( and even if you did) the motor is damaged and that is causing the circuit breaker to trip. You need to have the motor inspected to see if the damage is repairable or if you need a new motor. A local electric motor repair shop should be able to take care of that for you. The thermal overload has reset itself if after cooling down the motor is trying to start but trips the breaker.

To be certain it is the motor, disconnect the line leads and be sure they are insulated from ground and one another. Turn the breaker back on. It should stay closed which confirms it is the motor tripping it when connected.

If for some reason the breaker still trips, there is a problem with the electrical circuit feeding the pump.

Check the line voltage under load first to be sure it is not dropping to low and if it checks out, yes, get a warranty replacement.

Lubricate ao smith motor

If there's no grease fitting (ball bearings), remove the endbells and manually force grease into the bearings. On sleeve bearings use oil (2in1 oil is ok).

Motor is frozen.

Unlessyou can find an HVAC shop with a NOS motor for this unit you will notfind a drop in replacement. Even if you do get lucky and find a NOSmotor be prepared to pay nearly as much for it as you would a whole newevap cooler.

That said, there are motors out there that will work, but you're going to have to make them fit with custom mounts.

It'sstill a little spendy, especially if you want two speeds like theoriginal motor had, but you can get out for $80 or less if you'rewilling to settle for one speed (on/off). has a "Packard 40066" compressor motor for $69 plus $13 shipping. It may work but has only one speed.

Basicallywhat you're looking for is a "48 frame", 1/8 hp, direct drive,110-120v, 1075rpm, 1/2" shaft diameter and around 3" in length (to giveyou flexability when mounting), "totally enclosed" or "open drip-proof"housing (NOT "open"). Rotation can be either CW or CCW as you can mountthe motor on either side of the housing and some motors are reversable.If you've got the skill to custom make some mounts then you canprobably fudge some of these specs. The ones you can't change are the1/2" shaft and the RPM. Do not exceed 1075rpm. The blower assemblysimply can't be made to go much faster in that housing and if you tryyou will overheat the motor and burn it out very quickly (trust me onthis one!). Most of the cheap motors I've found are 208-230v and I justdon't see the point in having a small 220v PORTABLE evap cooler, that'sjust dumb.

After a LOT of online research I've found thefollowing motors that would be a suitable replacement, with all theabove mentioned specifications. I'm sure there are more, but crossreferencing this information for someone not in the business is trickyand time consuming.

AdobeAir 1/8 HP 115V Motor for Adobe MMB10A RF031095 $116.66

AdobeAir RK232A check
Emerson K55HXKZT-9867 is a good resource but they are expensive.

The motors listed are suitable replacements, but have only one speed, "ON" or "High".

Good reading for selecting a replacement motor:

Isuppose that if you found a smoking deal on eBay for an "Open" typemotor you could try it, but I doubt it would last long and make damnsure that ****** is grounded well.
