CHALLENGE

This Supertec DL 47118 spindle spun freely by hand when it arrived at Northland Tool, but was noisy.  After completing a full breakdown and evaluation, we recorded that the #1 and #2 bearings had very little grease left and some contamination. Lastly, the front cover and shaft nut were both heavily rusted and the rear bearings felt rough when spun by hand.
