My Lot O Tumbler motor died after just over 5 months of use. Looks like the bearing ceased up and the shaft ground against it making grooves in the shaft. Looks like I am getting anb MT4 or take a chance on a replacement motor.

I did read somewhere on this site that Shawn, at the Rock Shed, replaced a Lot-o motor with a "concrete vibrator motor" and said it was working OK at the time of his posting. You might want to check with him directly and see what he has to say. I have a new Lot-o myself and I'm crossing my fingers it keeps going. The odds are against it though. Let us know what you find out and what your solution is. Maybe someone else on this site has some suggestions. I've also heard that a "Imesa" motor is a replacement motor. I looked it up but there are so many Imesa motors on their site that I don't know what model number is the correct replacement. Maybe someone else has the correct model number and can let us know.

maludin - I also found a reference for the older motors that seemed to fair better was an A.O.Smith motor. I believe the part number for that is JB1P107N. Perhaps one of our more senour members can help on information on the Smith motor. I did see where Smith sold out to Century Electric Motors some time ago. Again, I hope some of our more experienced members can give us more information on the Smith motor and the Imesa motors. For what it's worth, I just went out and checked my Lot-o and noticed that there is a lot of wobble on the fans on each side. The weights are in the same spot on each side but it appears that the "out of round" wobble is uncorrectable. I tried by moving the fans in and out a little, to no avail. Anyway, I hope you find a reasonable solution to your problem and will let all of us know.

My Lot-O motor died on Christmas eve after about 9 months of running (Fasco motor). I guess I should consider myself lucky. I had ordered the ToAuto 30W vibration motor mentioned in other threads as the one used by Rock Shed. I got it a couple days ago and have been working on installing it. I just started it up today and so far it is running great and much, much less noise than the original motor. I am working on a write-up of what I did and pictures to go with on how to modify. Should have it in the next couple of days. So far just running some rocks and pellets to make sure it does ok. I plan to update on how it is doing but for $39 it seemed like it was worth a try. You will need to modify the Lot-O frame to install this motor.

So are the current Lot-O's being sold with the imesa motors? If so, maybe we will be able to get imesa replacement motors as they must be better than the crap Fasco ones. And chris1956, I would love to get a copy of the instructions. If the modifications are simple enough, maybe I will give that a shot also!!

I am not sure if the Fasco motors are the ones on the current Lot-O. I have seen some discussion about them being good motors when they were used for other equipment. I also recall that there is a delay in getting them now. I checked Kingsley North and they have the Fasco replacement motors currently listed as out of stock ($145). I am not very mechanically oriented. You will need to be able to use a drill and hacksaw (drill and cut metal) and a set of wrenches (both socket and standard as there are some tight places to get to). Once you make the changes it would be difficult to go back to the Fasco/Imesa motors. You would have to weld the lower motor supports back on the unit. The vibratory motor may not be for everyone but I figured it was better than waiting for months for a replacement motor that might or might not last long.

You will need to modify the Lot-O frame to install this motor. Looking forward to seeing your write-up. When you do it, allow me to suggest starting a new thread for it if you haven't already considered that. Otherwise, if you drop it into a current thread about failed motors, it will likely get hidden and become more difficult to find.

malduin I'm sorry to hear your motor died. I really like the results the Lot-O gives but if I had known about the Q/A problems they are having right now I probably would have gotten an Mt-4 as well. Diamond Pacific really needs to step up their advertising a bit because I could not find much info on them when I was first researching which led me to believe it must not be that great. They need to get a few units to some Youtubers to review. I did read somewhere on this site that Shawn, at the Rock Shed, replaced a Lot-o motor with a "concrete vibrator motor" and said it was working OK at the time of his posting. You might want to check with him directly and see what he has to say. I was the one that posted some pictures and video of that, but I was just sharing what Shawn had shared with me at the time, which was in September. They had been using the motor since July. IF someone wants to reach out to The Rock Shed and see how the motor is holding up 6 months later I think we'd all be curious to know. I know the motor is rated for the load, but that doesn't mean it will hold up to long periods of continuous load. I looked it up but there are so many Imesa motors on their site that I don't know what model number is the correct replacement. Maybe someone else has the correct model number and can let us know. Here are the pictures I took of the Imesa motor before mounting it to my frame. The model numbers appears to be 8211915139. Not sure if you can buy it directly or not. So are the current Lot-O's being sold with the imesa motors? Hard to say at the moment. In my thread, someone that had just bought a brand new Lot-O that had been assembled in Nov 2022 had a Fasco motor. That is the same month I got the replacement Imesa motor. So I think this means two possibilities. 1. They are ordering motors from both companies and it's random chance which one you'll get on a new unit. 2. They are still using Fasco for new units but are supplementing with Imesa for replacements. But with a sample size of 1 we can't know. We'd need more people that have bought a new Lot-O since November to chime in. I have seen some discussion about them being good motors when they were used for other equipment. I don't know much about motors, but I think Fasco is a good brand in general. My Lortone 33b and QT6 both use Fasco motors and have been running 24/7 for almost 2 years now with zero issues. I suspect the motor for the Lot-O is not properly specced for running an offset weight 24/7. This is probably why the warranty is only 3 months. I just started it up today and so far it is running great and much, much less noise than the original motor. I am working on a write-up of what I did and pictures to go with on how to modify. Should have it in the next couple of days. So far just running some rocks and pellets to make sure it does ok. There will be a lot of people interested in that. I agree that you should make a new post for it, but I'd then link your post in this thread and in my thread I made about the Lot-O motor earlier this month.

Very good information Gentlemen! In regards to using an Imesa motor as a replacement, is it a direct bolt in or does it require some modification to the unit or the motor? The concrete vibrator motor sounds great from an economical standpoint but I'd like to see how much modifying has to be done. Personally, I want to thank all of you who have responded to this concern. Every bit of information we can get is important to making a sensible decision. Like the rest of you, I like the results I get with the Lot-o only having it for a very short time.

That's the main reason I got it instead of the concrete vibrator. But if it breaks.... I am not paying that much for another motor. At least not within a reasonable time frame.

I will try to get everything written up this weekend and post on Monday. I haven't started a thread yet but will read up and ask questions if I have them.

I got an availability notice from kingsley north for a replacement motor so I snagged it. Will give it one more chance, if that one fails then will look into the modded motor that chris1956 will be posting about shortly.

Well add my lot-o to the list of lot-o's that had the motor die in less than a year (8 months). Gonna get a p-tech off of Amazon. If that doesn't work I'll mod the frame to take a concrete motor.

I put one of those concrete vib. Motors in my uv-10, been about six months, no problems. They are a pretty durable motor.

I have one of those concrete motors and a speed regulator, but I need to modify the lot-o frame to mount it. Since it requires a modification I can't go back from I thought I'd try the P-tech first?? It is made for vibrating beds hahahaha. Not even sure it will fit, but I can return it if it doesn't. I do think I'll be using that concrete vibe down the road some day . . . .

Yeah this Fasco motor just isn't designed to handle the vibrations caused by the weighted fans. You can see below that the magnets on the shaft were hitting the magnets on the body of the motor, once it got out of balance I am sure it just got worse and worse. They are using a motor for a purpose for which it is not designed.

Would love to know the process. id love to post pictures, I can’t figure out the instructions. I can build a house and anything else, can’t figure the instructions out. If you are on Instagram, let me know, I’ll post a video.

For what it's worth, my replacement motor from January is still jugging along. Though, who knows how long it will last?
