In con-nection with the reclaiming of GE-57s, the axles havebeen inclosed with a cast-steel shield made in twohalves, one section being electrically welded to the topand the other to the bottom half of the motor frame, thejoint between the two halves being machined with anoffset so as to make it dust tight. This arrangementas well as the practice of reboring the frames has givenvery satisfactory results and has been the means ofconsiderably reducing the cost of maintenance. Theshield is shown in the two small illustrations in the Ha RECLAIMING GE-57S—SPOOL GUIDE FOR BORING BAR RECLAIMING GE-57S—REBORING THE AXLE BEARINGS January 15, 1916] ELECTRIC RAILWAY JOURNAL 133
