I took everything apart again this afternoon. I removed the bearing grease and used sewing machine oil instead. The saw is running fine right now, so I guess that worked. Thanks for the help, I really appreciate being able to come here and be pretty sure someone will be willing to help out. sounds like you did fine, but just in case.. there should be 'bearing' grease on the gears in the gearbox, just not on/in the bronze bushings .. Now I’m confused. I have removed the bearing grease and replaced it with sewing machine oil. The oil (not grease) is one on the gears and the bushings. Should I put the grease back on? |

Now I’m confused. I have removed the bearing grease and replaced it with sewing machine oil. The oil (not grease) is one on the gears and the bushings. Should I put the grease back on? This is a shaded pole motor with a Gear box attached. The scintered bronze bushings of the motor have small capillaries that allow oil to flow from the felt pad and lubricate. I'm sure there's a bunch of youtube videos of cleaning small fan shaded pole motors wo gearboxes as they tend to fail because these bushings get contaminated. Gear boxes usually contain grease for longevity. With oil only in there it may still last for years, but, I do think the old brevel motors give off some heat in that box, and grease was in there from the factory. 2c. |

Those shaded pole motors have extremely low starting torque. Bearing grease will be too thick to use in cold weather. I would recommend 3n1 or some sewing machine or clipper oil. When things warm up you can shoot some Lucas or something in there. I still think some cold thick grease was the problem. But I was speaking from the motor aspect of it. I don’t have experience yet with the slab saws. They make a product called gear lube that is very heavy oil. |

Back when I took apart mine and re-lubed it I know I used something thicker on the gears. It was one of these two items. Seems like I remember using the wheel bearing grease and just lightly rubbing it around on the gears. Gear lube is thicker then standard motor oil but is still pretty thin and would not stick to the gears. It is made to be squeezed into automotive rear end gear housings. The wheel bearing grease is thick and clingy.  Chuck |

Thanks again everyone. I'll do some more research, maybe I'll contact Lortone if I can't find anything myself. They were very helpful when I called with questions another time. oregon, thanks for pointing out where the oil goes and where the grease goes. that makes sense now. |
