CHALLENGE

This Umbra S.30.084 spindle rotated freely when it arrived at Northland Tool, but the bearings felt worn when spun by hand.  After performing a full breakdown and evaluation, we noted that the front bearing felt very worn.  The grippers had a few broken fingers so no incoming pull force was taken.  Lastly, the field passed our incoming motor analyzer test.  No dimensional deviations were noted for this repair.
