Removes and installs tapered roller bearing OEM #45700009 (MCS 577074) at base of steering stem. Used to install & remove the lower fork stem bearing at the base of the triple tree without damage to the fork stem. Removal process requires cutting the outer sheet metal cage (that holds the rollers) of the tapered bearing; this will separate the bearing rollers and cage from the race. Now the race can be pulled. A bearing driver adapter is included and used to install the new bearing. Tool can be used when steering stops are installed. Durable black oxide finish with laser engraved logo
