2011 Ferris IS3100 Blade spindle assembly rebuild
part number for spindle assembly: 84007984
Ferris has modified these spindles over the years. I have a newer mower that uses the same bearings and all the dimensions are the same except the height of the spacers. Later on they went to a double row ball bearing. They are just as easy to rebuild but the dimensions are metric on those fyi.
