Step 2
When you're searching for a Marathon replacement pool motor the key pieces of information you can have are the Model (MOD) or Catalog (CAT) number. These numbers exactly identify the motor and ratings, when entered into Inyo's product search engine a drop-in replacement can be found.
A model number for a Marathon Pool Motor is listed on the left hand corner of the label. This number has a distinct format which will begin with a "5KC" with eight to ten interchanging numbers and letters following. For example, 5KC38SN6084X, as is this number can be searched in our product catalog.
The Catalog Number (CAT) is listed on the left hand corner of the motor. Its format will begin with a "C" with four digits after, for example C1245. If the model number not available use this CAT number to search your pool pump motor match.

I need to replace the bearing(s) on my MOD5kc38sn6084ax, CAT c1245 motor. Do you happen to know what would be the numbers for the bearings? Thank you.Reply
InyoPools Product Specialist Matt S. Posted: 7/23/2021
Hello - The C1245 pump motor uses two of the 10000353 bearings.Reply

Could you tell me what the replacement would be for a Marathon 5KCP39RN4198X? Also, is there a specific Go Kit that needs to be purchased with this?Reply
InyoPools Product Specialist Matt S. Posted: 12/7/2020
I am unable to find a match for that motor number. It is probably a small batch made for a specific manufacturer because it is on a spa pump. They make those numbers extra obscure to make the spa owner go through the local dealer to replace them. Do you know the model number of the pump housing that motor is mounted to? I may be able to find it that way.Reply

The gaskets are matched to the pump housing and not the motor. What is the model number or make and model of the pump housing?Reply

need to replace an impeller for a Marathon 1hp pool pump ,mod.5sme29dft002Reply
InyoPools Product Specialist Matt S. Posted: 4/24/2020
The impeller is matched to the pump housing. Marathon is a motor manufacturer, and their motors can be fitted to dozens of different housings.The easiest way to find the replacement impeller is to search for the part number on the old impeller.Reply

Unfortunately, there is no cross-reference to that number. You may want to try verifying that you have the number copied down correctly.Reply

looking to replace 5kcr39un3625ax but the search doesn't come back with any results. 230v 60HZ, 6.90/2.6 amp, 56Y on label but it measures as a 48 frame. Any help would be much appreciated.Reply
InyoPools Product Specialist Matt S. Posted: 12/9/2019
That catalog number does not appear in any database or even a google search. Can you verify that is the correct number listed on the label? Is this on an inground pool, above ground pool, or spa pump?Reply
Brian Posted: 12/10/2019
It’s from a 1996 marquis builders series hottub. I have a photo of the motor label I can send.Reply
InyoPools Product Specialist Matt S. Posted: 12/11/2019

Struggling to get true nameplate specs on Marathon motor 5KCP49TN9113x. Any help ?Reply
John A Posted: 3/18/2020
Dear David, It looks like we too are struggling with the same Marathon Motor for a spa application that has failed in less than 4 years. Did you find a suitable replacement? Thank you.Reply
InyoPools Product Specialist Matt S. Posted: 3/19/2020
The closest thing to a replacement I could find to the 5KCP49TN9113X motor is the Century 2.0 HP Thru-Bolt 48Y Dual Speed Motor - BN51. Do the ratings look similar to the ones listed on your label?Reply
InyoPools Product Specialist Matt S. Posted: 9/12/2019
Is this on a residential or commercial pool pump? Also, is it a DC or AC motor?Reply

The Marathon is the pump motor, its replacement is the B853 1HP Square FlangeReply

CHARLIE - If you are asking if these 2 bolts can be replaced, I don't have the specific part number for these bolts but here is a link to our Thru Bolts page. Match to the length and diameter size. If you don’t know the diameter, take the bolt into a hardware store and they should be able to match it to their sockets. Paul – You should see a part number on the underside of the cover. Put that into our customer page and it will point you to a parts list for this pump.Reply

I have a model # 5kc39un2522dx cat. no c1306 1 hp 3450 rpm ...I am trying to get to the bearings. On the square end I removed 4 long bolts and nuts. There are 2 others, on the square end near the shaft. I know they will brake, that should be alright?Reply

Gerardo - If your 5KCR39SN2823AX motor is single speed (SS), your SS replacement motor is UST1152. If you have a variable speed (VS) motor or would like to convert your current SS motor to VS, replace your motor with an ECM16CU motor. In either case, remember to replace the motor shaft seal. We would need to know the pump model that this motor is going into to specify the tight shaft seal.Reply
Gerardo Posted: 2/27/2017
Cannot find model 5KCR39SN2823AX, what would be an alternative?Reply
InyoPools Product Specialist Dennis R. Posted: 10/24/2016
Mike - It looks like your motor 5KC38SN6084AK matches to a USQ1102 [5KC38SN6084X]. Note: Marathon motors were bought out some years ago.Reply

Aj777 - Your part #, 5KC36MN2533BX, references the motor on your pump. The replacement motor for that part # is A.O. Smith 3/4 HP Square Flange Up Rate Motor (USQ1072). Your motor's part number 5KC36MN2533BX, is included in the list of alternate part #s.Reply

Dave - This should be the replacement motor for C1247 - A.O. Smith 2 H.P. Square Flange Up Rate Motor (USQ1202). Check that the motor specs match those on your old motor label.Reply
