When we moved the knee mill (2J head) in to our lab the fuse case for the X-axis feed was busted. We replaced that, threw in a fuse, and it worked for a while. The handle did need to move slightly over center to stop the motor.
The other day the fuse popped, although not the one in the feed case. There is a box with a large transformer on the back of the column, it has a small fuse on the transformer that powers this drive and the DRO. Replaced the fuse, blew again. Moved the table a bit, changed the speed, replaced the fuse, blew again. Ok, seems I need to take it apart.
I don't know if this is a 6F or 8F, and (it wasn't me) a lot of the unit has been painted over. Reading other threads on here it sound like the common failure points are oil in the motor and oil in the electronics. We have plenty of electronics cleaner and denatured alcohol.
1) Are there any places I shouldn't open because oil will come pouring out if I do?
2) Are there any particularly good places to start?
3) If I do drain the oil out, what is the appropriate oil to replace it with? Is this something I should go ahead and do anyways?
I don't mind digging in and seeing what I find, but I'm wary opening something that's supposed to be full of oil without asking questions first. Pictures attached.
