Good evening . I am in the process of replacing the bearings in my 2J head. Looking on line I have seen a bit of discussion about the lube system and what grease to use. Also to use or not to use spindle oil. I will be ordering the H&W spindle repair kit. You can get open or sealed bearings. I have not decided what I am going to order as of yet. What have you done for spindle bearings and spindle lube in your machines.
