For all that have trouble getting the sight glass removed on a Wayne 60 this tool works every time. One or two good hits on the end of the connecting rod with your trusty hand sledge and that baby is loose without damaging the bezel. The connecting rod is out of a Cummins 855 diesel engine. Any diesel shop will have junk ones. I cut the slots by hand but I don't recommend it. Take it to a machine shop. If you only would use it once then you would be better off buying one of the tools offered in the catalogs but if you restore pumps you would make good use of this. You can't believe how good it works. I need to find the right size con rod for a Wayne 70 and make up one.Thanks for the help in getting the picture on.
