I am the other member Larry was discussing this with, I think. As I stated in another thread, I would be great if someone could do a tutorial and put in the library here of the process of greasing the bearings. There are a lot of DeWalt and Delta owners here. I do not know about it I have never done it. I have never heard this mentioned regarding the Excalibur saws. I know little about bearings, but what bearings I see in mine, I think they are sealed bearings, can't grease them(?).
