The cold chisel trick was the first thing I tried, and when I broke the cold chisel, I started looking for another way to get it off, The second thing I tried, was my jury rigged press, but it didn't budge it. That's when I mounted it in the lathe, and tried cutting it off. I DID get it off last night. There was a gear behind the race, and since it was already damaged, I had a brainfart, and welded a fairly hefty mount to it, took it back to the farmers shop, and mounted a 6"dia hydraulic cylinder to the mount. I pressed on the end of the shaft, while applying heat with a rosebud... The Hydraulic pump was straining pretty hard, so I figure I had well over 60 tons on it when the race popped loose. Of course, popped doesn't do justice to what happened when the race came off. I then brought it back to my shop, cleaned up the journal, welded it up, and turned it back to dimension. Handed it back to the owner, took a handful of meds, and passed out. The new parts should be in by 2:00 this afternoon, so I'll see if I'm a Saint, or Satan soon :) -- -Mark Ne M'oubliez ---Family Motto Hope for the best, plan for the worst ---Personal Motto ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
