A tool developed by Mark Brooadhurst to facilitate the installation of the drive side and rear wheel bearings.

The bearing is slid into place and secured by the O-ring. This allows the bearing to be seated perfectly in the preheated bearing seat. This is a particularly good strategy for the drive-side crankshaft bearing, helping to avoid any acrobatic maneuvers. 

In addition, if necessary, you can easily apply sealant to the bearings before installation.

CAUTION: Under no circumstances shouldthis tool be used as a striking mandrel.
