I was given a used lortone tumbler with a 1.5 pound barrel and after spending a long time trying to find a part supplier that was nearby. (Dowd supply in Ottawa, ON) I have been happily tumbling away except that recently the tumbler has a nasty habit of stopping for no apparent reason. I've tried cleaning the rollers, cleaning the motor, lightning the load in the barrel etc. So far I've lubricated the roller bushings with WD-40 but I have no idea if this is appropriate or how frequently this should be applies as there was no instruction or maintenence information with the tumbler. I think the tumbler is somewhat old as the casing is light green and all the tumblers on the Lortone website are Blue.
Thanks for your help
Alex

my instructions say "oil tumbler shaft bearings with one or two drops of lightweight oil (SEA 20). Repeat lubrications twice a month when tumbler is being used continuously.
Motor bearings are prelubricated at the factory and will not require oiling for approximately three months. Use a few drops of SAE 20 on both bearings at approximately three-months intervals."
"A drop of SAE 20 oil in the grooveof the knurled nut will eliminate friction and noise."
hope that helps some.

Have you checked to make sure that your belt is not slipping? The belts do get old and crack, and sometimes the motor pulley will set in that spot and the belt will not pull a load. And if you get some of that lubricant on the belt (especially if you are 'spraying' WD40) that will cause it to slip.

Either your motor is worn out, or the belt is out of line. I have had the same issue with my dual bbl tumbler and it was the motor. Lubricating the motor bearings will not really help. Look under the motor on the pan and see if you have black dust. If so the motor is on its last legs. This usually results in overloading the bbl. The cost of the motor is not much less than a new unit. You might consider a new unit and using the bbl from the first unit to use in an isolated grit run. Always use that bbl for a particular grit. Helps to eliminate cross contamination. Once you get the motor going on a tumble, keep the tumbler going when changing grits. The new grit in each batch will put a load on the already weak motor and it will have to be babysat for a while. Once it gets going it should keep going if it is not overloaded. The motor should not be stalled! That is how it got weak in the first place. I had to change the motor with identical symptoms you have described. Another important issue. Keep the tumbler level. You have to distribute the weight on the four legs evenly. An uneven platform puts unequal weight on one bearing surface which drags the motor down. With the smaller Loretone motors, the trick is to keep the load light on each bearing.

WD-40 , its a Water Displacing product.never use it for lubricating..or for that matter use it for anything..Im sorry but its crap. I am a shooting enthusiast and I hve listed to more horror stories about guns rusting because the WD-40 not only displaced the water ...but also the lubricant or rust preventative on these guns. If you want something great...3 in 1 oil is still hard to beat for things like this.

The light weight oil that you are using is that the same that would be used on sewing machines? Tami

Thanks for the advice, lubricated with SAE 20 3 in 1 and it now works great, 1 week continous now with no problems.
