Metric colors, eh? : )
Yellow/green is the ground, blue is the neutral and brown connects to the hot leg.

I'm in the process of replacing the motor of my double Lot-O. The motor I ordered was supposedly branded Bizoepro (what my order said, but no name on the motor-probably coming from the same factory) and appears the same as in the photos of the previous build (The Rock Shed?). This motor has four wires coming from the motor (yellow/green stripe, blue, brown, and black) into a plastic box (capacitor?), with three wires coming out of that box (yellow/green stripe, blue and brown) for a plug. I know nothing about Chinese wiring colors, so....if anyone has completed this mod, how did you wire the plug? I went with the concrete vibratory motor for the replacement motor. The wiring matched up with standard plug. I am sure there is somebody out there that will know the answer. It does make me mad that the manufacturers for a lot of the products now coming from China don't even put their names on their products. Makes me think they don't want to here from anyone if something goes wrong. |

Just as parfive said,yellow/ green wire to ground (green), blue to neutral(white) and brown to hot(black). Screw on plug for hot will actually be brass colored. Neutral on plug will be silver and ground will be green.

Great post chris1956. I think I'm a candidate to try this. I bought an old used Lot-O last week and it works but the motor is messed up. It's very loud, I think the bearings are shot. I can't think of a better time to find this post. Thank you. I'll check back in if and when I get it going. Doug |

I can't think of a better time to find this post. Thank you. I'll check back in if and when I get it going. Doug Chuck of Drumond Island Rocks ( Drummond Island Rocks) came up with a good idea if you have the ability to get a plate and tap holes. If you don't, in this post he talks about how the concrete vibrating motors were originally added. Note that on the 6th photo he put nuts between the frame and the base of the concrete vibrating motor. One of the problems I had is with heat transfer from the motor to the frame and to the barrel. I think it ended up casuing some wear on the barrel. I figured out a way to overcome this but I think adding the space with the nut will help reduce this heat transfer and keep you away from that problem. forum.rocktumblinghobby.com/thread/106150/motor-swap-cutting-original-frameI couldn't find the original post where Chuck showed the different steps but here is a link to a couple of Chuck's videos that might help. forum.rocktumblinghobby.com/thread/101420/lot-motor-concrete-videoGood luck and let us know how it works, Chris |

Hello chris1956 . Update to the used Lot-O I bought. I found waterboysh thread for the Lot-O motor issues and saw he took it apart. I was afraid to take it apart because I didn't think it could be taken apart. So I took the motor apart and the armature and stature were totally rusted so I cleaned them off with steel wool. I oiled the bearings and they work smoothly. I assembled it and ran it and it worked very well at first then it got really loud again, and I noticed left to right movement in the shafts with the cooling fans and counterweights. The shaft was loose and that can't be right. That's when I decided to order the concrete vibrator motor. So this morning I thought I would take another look at the motor and noticed the bearings on the shafts of the armature were spaced unevenly which was causing the side to side movement, one side was about 1/4" further out than the other. If you look closely at the shaft you will see five groves that hold a retaining ring. I moved that ring out one grove so the bearings would be spaced evenly on each side. Reassembled it, mounted it, and turned it on and Voila, very smooth and it is pretty quite. I think I fixed it. I even started the first batch.
Oh, one more thing. I was securing the lid with a small bungee cord because I didn't have any rubber bands, but I thought it was a little too tight. I said to myself, what if there was a way to hold the lid tight without using rubber bands and it so happens I had an O-ring that fits perfectly around the lid. It might vibrate off so we'll see if it works.
Thanks again for all who contributed to this thread. You all saved the day.

The ToAuto motor conversion is complete and the recently acquired old used Lot-O tumbler is restored and works great! I thought I had restored the original motor well enough, but that was short lived and not to be. It has seen it's better days.
The idea of using an O-ring to keep the lid on didn't work at all, so I'm using a bungee cord until I find rubber bands.
Thanks again to all who started this thread and the first to try the ToAuto motors. I'm over the moon to have a Lot-O Tumbler in my arsenal.
