Replacement motor for Thumblers UV-10 vibratory tumbler

MrK.

Anyone replaced a motor on a Thumblers UV-10? I bought this one used back around 1990 and it has been reliable since then. I was running it yesterday afternoon and came out to the shop after supper to turn it off. I noticed that it was kind of surging. I took a good look at it this morning and noticed that a chunk of the housing was broken off. I disassembled it this afternoon and the bearings are good but the piece that holds the bearing steady has disintegrated. I have been looking online and cannot seem to find a direct replacement. I did find a replacement for the industrial version for $175 but mine is a standard. I'm wondering if anyone found one to retrofit.

I just recently ran into the same issue. You can call Tru Square 253-833-2310. I tried to buy one a month ago and they didn't have one in stock. I think it was$280 for one. You can look for a FASCO (name brand of motor) Type U21 1-30 horse power motor. They are made for AC fans. You might try Grainger or EBay.
 
Try your local heating and air conditioning supply store. They should be able to match one up.
 
Got any pictures of damaged motor. I have one of these tumblers and the end cap of my motor broke loose from the outer round part of the motor. The end cap has little notches that located it into the outer diameter of the round part, and they they were spot welded in place. Those little spot welds broke loose and the motor wouldn't work. I just lined it all back up and rewelded it after I didn't have any luck finding a reasonably priced replacement motor.
 
I think I am going to give THIS one a try. Mine has 4 mounting studs and this only has two but I will try to figure something out to mount it. Below is a pic of my motor before I removed and disassembled it. You can see the part of the housing broken off.IMG_0307.JPEG
 
According to pics of the Thumblers unit, the motor does resemble , if not mirror the bathroom exaust fan motor. Might be a simple replacement. If you do go with new tumbler, a reminder to save the bowl components to use as a swap between different medias.
Good luck with your conclusion.
 
I tried a Grainger motor on my Dillon. It lasted one load of brass, the fart fan motors are not designed for the vibration, I eventually sent mine back to Dillon, It was too much money to ship and for the repair. Their insurance would not trust me to install it and thought I would burn my house down and blame them. If I had it to do over I would buy the biggest Dillon (even though i don't need the size) and be done with it for life. Whatever you do, get the motor Thumblers recommends they know what lasts and what doesn't, I thought i could use a fart fan motor and it was a waste of time and money. The original Dillon motor had an extra out board bearing and a bracket to hold the bearing I added that to the new Gringer motor. I didn't help, I assume the original had much better bearings, and some way to deal with the vibration. Good luck hope it gets fixed soon!!!!!

I went down this road last year, Both my tumblers went south. I cant stand to throw stuff out when I can fix it. Tried the grainger motor route, burned it up, made a new bearing holder, that fell apart. modified mounting to get something else to fit from amazon, finally just ordered a new Frankfort from amazon when they had them for $45, almost thinking im getting a new tub and motor for less than a motor for the old one. Well i liked it, and got another one. then midway had the lyman 1200 on sale for under $50
got 2 of them. My old dillon and midway branded one lasted nearly 20 years, just had to accept that i got my moneys worth and get new. the lyman is made by a company that lyman owns and you can get new motors from them, but its just cheaper to get a new one when there on sale and pitch it. I like the berrys brand, it has a tub that comes off, but i didnt find any sales on them.
 
My Thumblers, in use since about '83 finally went out a year or so ago. That's very good performance. Sent it to Thumlers, they replaced the motor and sent me back what's essentially a new tumbler. Cost about $85 if memory serves. I'm very satisfied. This thing will outlast me.
 
I have a thumbler B rotating drum. The only place I saw parts was a place called the rockshed .com. They usually had motors for vibratory tumblers also.But the motors are never in stock. If you can find one for about 100 bucks I would consider it if it s made specifically for that tumbler. Ive gotten 20 years out of mine so It owes me nothing.
 
i have the Thumler's Model A-R6 Tumbler its motor looks much like the fan motor for my pellet stove that I recently replaced .
discovered a quick easy way to get rid of the suds ,used a torch

when my Lyman 1200 gave it up I had thought of replacing the motor.replacing the whole thing was easier

Purchased one in the mid-80s and another 3 or 4yrs ago, the new one is SO much quieter. I won't replace my old Lyman when it dies, the Thumlers B does a much better job and almost silent.
 
So I believe what happened to this motor is that some shim material between the bearing housing and the bearing itself disintegrated over time. This allowed the bearing to move back and forth which caused the pot metal housing to fail. I could secure the broken piece back into its spot with a hose clamp and then I cemented it in using the super glue/ baking soda trick (3 layers). The crumbled shim material had the look and feel of aluminum foil. I tried several times covering the bearing with foil and pressing it in but each time it would not be perfectly centered and would drag while running. I think this is because the foil would bunch up in places, and be single thickness in others. In a final hail Mary I decided to center the bearing in the housing and glue it in place with JB Weld. I let that cure 24 hours then threw in a handful of Grendel brass and turned it on. It has been running on my workshop patio for the last hour with no hiccups thus far. I'm on my way to the ranch for a few of hours of shooting and I lay the odds of it still running when I get back at 30%. If it fails again I will purchase the Frankford Arsenal version off of Amazon for about 60 bucks. I will keep this unit just in case someone gets a replacement motor for it at a reasonable price.
