Jay successfully installed the roller bearing using a ball-peen hammer and light, dispersed blows to get the bearing started into the bore. Once the bearing was started, he placed an aluminum slug over the top of the bearing and pounded harder. After a little more hammer work, he carried the assembly over to the hydraulic shop press and squeezed the bearing into its final position. A solid surface was used beneath the entire Lefty case, so as not to punch through the thin wall at the bottom of the bearing bore. The retaining bolt received a drop of blue Loctite before being threaded into its final position.
