130 direct drive motor question

PostBy: plumberman On: Mon Jan 26, 2015 7:54 pm

heres for the peanut gallery, last year[first season] lost the end switch for start winding, got parts from local motor shop and repaired, bought new baldor motor from on line supplier, and fan blade from ahs for [the shelf]. got home tonite and caught motor screwing up, changed out to back up motor, easy breasy done, havent pulled motor apart yet but going to bet bad end switch again?? seen on their post here they list a hd end switch and also conversion kit to belt drive, not sure if i am going to order new switch, new motor, or convert over, looking at all possible choices. am i the only one with 2 end switches in 2 years? any one else convert over to belt drive?

thanks for any input :D

I've been telling everyone that the only trouble I've ever had with the AHS 130 is the damned direct drive motor. It is 3/4 hp, draws a lot of juice, and cannot dissipate the heat from the shaft. I have converted the ones that were direct drive to indirects....no more issues. That motor is a Jacuzzi spec motor, but the heat transmitted up the shaft is tough on bearings. Not a cheap replacement......something like $350.00, however you will wonder why the hell they still make and sell the direct drives. For any units that I find for sale, automatically chop off 700.00 for the kit and a little labor. I am surprised that you did not mention removing the fan from that shaft,,,,,,Harry Houdini can't do it with a 55 gallon barrel of Kroil....I've tried 5 and only saved one....don't like those odds.

Electric motor shafts soak up heat like a sponge.

The heat created by the motors rotation and the
electrical fields also compounds the issue and
costs more money.

gave a call today to ahs, they said they would give me credit on fan blade that i bought last year for a spare[unused] towards a belt drive kit. so i'm in the process of going through with it, when all said and done i'll have the direct drive unit as a back up on the shelf if need be. this is the second time after the sale dealing with them and i cant say anything bad, top notch nice folks!
