1725 RPM Motor replacement recommendations please...

swihart_art

My oil furnace has been tripping the safety switch on the motor lately... that motor is probably 40 years old and it trips once a week or so... can anybody recommend a good source to buy one online to replace it? Here is what I know about it:

- Burner is really old, pump is a newer (4 years max and changed coupler too) 1725 RPM so I'm assuming it needs to match.
- Not sure how many HP it is but I see lots of 1/6 and 1/7 motors used on Becketts
- Little red button pops out so something is overloading it or it's just old... I see no oil ports on it so think it's sealed.

I think that @EdTheHeaterMan has a signature line that covers this

I do have a signature line that covers that. LOL

This is your motor.

But it may not be. Check the dimensions.

And after you replace that motor and the same thing happens, What will you check next?
Check the pump strainer and the oil filter and the burner fan. If there is a build-up of foreign matter, then cleaning it might help. That costs less too.

I don't suppose there is a nameplate on the motor somewhere?

Check myself for not properly troubleshooting...

It's somewhat loud too... "growl"... we've had that furnace for 40+ years and that motor is original so not surprising, I think the bearings are worn and it overheats at times... just wondering if there is a go to place online that someone can point me to for affordable replacements, I'm searching now and there's lots out there and the pricing is wildly different...

Check the voltage at the motor with it running too, make sure a loose connection or bad contact in a control hasn't caused it to try to run on low voltage and overheat

Thanks for the tips, I just changed nozzle and oil filter while I was up there but didn't check/clean the strainer... fan is clear of debris, appreciate your help with the link...

Most 1940s and 1950s oil burners used the same standard oil burner motor. https://www.supplyhouse.com/Century-XEL2014-5-5-8-Oil-Burner-Motor-115V-1725-RPM-1-6-HP You are probably correct about the 50+ year old motor. Especially if you never added any oil to the bearings. (Permanently sealed or not)

@swihart_art , can you post a pic of the burner? Many burners did/do use standard motors, but you never know...............

The frame # off the name plate will tell the story
