After a year I have brought my rotary tumblers in from the shed, they worked perfect last year , now the barrels stall and don't rotate. The barrels will start to rotate and then then just stop even though the spindles are still turning. It is an older lortone that can run 1 12# barrel or two 6# rubber barrels. I'm having trouble with the smaller barrels. I have tried the following: adjusted the motor so belts are not too tight, removed, cleaned and oiled the spindles, put masking tape around the rubber barrel so there was more friction, ruffed up the spindle sleeve, put less rocks in barrel. I've run out of ideas, can someone help me. thanks.

sorry to hear this sounds like you've tried lots of fixes I did too... with my tumbler Only way I could get it to roll is tilt the machine
the 'tilted tumbler' thread is just below this one there was lots of info
hopefully someone with more knowledge than me will have a solution
happy tumbling

I've had the same problem, caused by not having enough in the barrel, rather than too much.

Although you've tried a few things I'll try to go through all of the ones I know of. Start at the motor and make sure the small pulley is not spinning on the motor shaft. Check to see if the belt slips under a load. Check to make sure there is NO oil or oil film on the rubber rollers. If the rubber rollers are "glazed" or have residue from the barrel on them,rough them up with 120 emery cloth,,,sometimes a good cleaning with acetone works to make sure the rollers are clean and dry. Although the Lortone barrels are pretty tough,in time they do wear down and the aluminum barrel cover is all that's really making good contact with the rubber rollers.If this is the case the only remedy I know of is to buy new barrels. Check to outside of the barrels to make sure they are clean and don't have a "glaze" on them.If they look shiny,rough them up with 120 emery cloth and wash them off good with liquid dish soap. If all is well the barrels should rotate without any rocks in them so the size (or weight) of the load doesn't make any difference,however,a heavier load will rotate better in older tumblers that have worn parts. If the tumbler is old,the rubber rollers may have gotten hard which makes them become "slippery" so the barrels slip rather then "grip" the rollers. Masking tape can be a bit slippery as well. It's just a process of elimination to see what is causing the barrels to slip and if you go through them all I'm sure you'll find the answer. Good luck. connrock
