Help! The barrel keeps on stopping. I've cleaned it, belt looks good. Barrel is not even half full I put my little 3lb barrel on it and it didnt stop turning. As soon as I put this barrel on it stops Uugghh and I cant load video

Might be harder to turn a half full barrel than a full one? just throwing that out.

Ali, does the roller under the barrel stop or is it just spinning under the barrel? Bill

Is the motor still turning? Sometimes the aluminum pulley on the motor shaft wears so the belt bottoms out and will not create enough friction to turn the tumbler. The belt may also have worn down in width and as a result is bottoming out on the pulley resulting in the same dynamic. Solutions are to 1, get a new belt if it is worn, 2, get a new pulley and belt if the pulley is worn , or 3, get a new motor if the motor is not able to turn the barrel. I hope this helps. (Is your belt tight enough?) Is the second roller turning freely? Bill

Not too tight and what I found on YouTube, it's not too loose When I put the 3lb barrel on it, it spins no problem Added more rocks to the 4lb woodman and it hasnt stopped, but isnt spinning that fast either. For now it is working

Look at it running with out the barrel and with it, look for which part is running slower. if everything, motor may be getting weak but it really sounds like you have something slipping someplace.

I recently replaced belts and adjusted tension on my QT12 and QT66 for the same issue. They hadn't been changed since I got the tumblers. Running fine now, and RPMs picked up.

Sometimes belts get worn or glazed enough to slip a little even when the tension is okay. A quick spray with some belt dressing will usually give it enough grip to work.
Warning - it softens the belt surface. Too much - or a fast moving belt - will cause dissolved black rubber droplets to fly all over the place.

Thank you all VERY much This gives me some things to check and try 1st thing Belt spray and figuring out how to adjust the tension And I may be asking some more questions

Allison MsAli. When the barrel is on the rollers and turning, what happens when you stop the barrel by placing your hand on it? If the pulley keeps turning, slippage is an issue. I'd look for a new belt if you can't get any more adjustment out of it. If the pulley stops as well, it's probably the motor that needs replacing. Normal RPM's of the barrel on the 45C is 34. I got that directly from Lortone in a phone call.

So when you stopped the barrel with you're hand, the pulley from the motor kept spinning? IF so, it's a belt issue (slippage). I know I may be repeating myself, but I just want to be sure about what we're talking about. If it's a belt issue, you may have some play in adjustment to tighten it up. If you max out your adjustment and the pulley still turns after you stop the barrel with your hand, get a new belt. If the pulley doesn't spin and stops when you put your hand on the barrel, then you have a motor issue. Don't bank on age. These things come from China, and all bets are off as to how long they will last.

The motor mount holes are elongated so you adjust by loosening the mount nuts and moving motor out. Lortone belts are pretty notorious for stretching and a lot of "broken Lortone tumblers" only need a belt or adjustment. When I was a Thumler's dealer I used their "A" model belts on used Lortone 3 lb. tumblers. They are the clear belts and I think they stretch less. Same size. Another trick with barrel tumblers is to put braided type hose over the roller shafts (Tygon is one brand but garden hose that has the reinforcing braiding works too). I remove the worn smooth old covering and slide new hose on but some folks just split the hose and glue over. For the math wizards it changes speed of barrels slightly. Your problem sounds like belt issue. While you are at it look at the plastic shaft bushings. Cheaper to replace the bushings than to wait until shafts are worn also. I have had to replace shafts on used Lortones because of lack of maintenance. If I recall, every used Lortone I have bought needed either a new belt or belt adjustment. I'm guessing the newer motors are not as good as the older ones so shorter motor life is likely to be found. Why are you running 1/2 or less than 1/2 barrels? If you get it to work, you won't get good results. When you get closer to polish you will find the rocks being damaged by falling rather than rolling. Best to keep minimum 2/3 full, better at 3/4 full. If motor too weak use light weight fillers.

A really HUGE thank you to Dave for giving me a call and walking me through what to do. Now I have a plan and some tools to buy😊
You all are the best and I appreciate the help.

Hi MsAli. All good troubleshooting advice above. I personally would disagree with the suggestion for belt dressing. In my experience it is a short term, messy band aid for a problem that is easily and permanently repaired by adjusting or replacing the belt (if that turns out to be the real problem). No disrespect intended; just a different perspective. Good luck!

No disrespect intended; just a different perspective. Good luck! No disrespect taken. Belt dressings are definitely short term - and can be the worst kind of messy. That's why I included the warning about the nasty dissolved rubber droplets.
I do use dressing sprays on saw belts sometimes if I've put off buying a new belt for too long and I'm in the middle of a rock I want to finish. It will fling black spots of rubber up the wall, across the ceiling, and all over anyone standing in the way if too much is applied.
Thanks for reinforcing that message. I'd feel bad if someone used the stuff on a machine inside a nicely painted room.

Ya not sure my apartment management would appreciate that
