Inner Bearing Cavity Here is a view of the socket for the inner bearing. You can get an idea of the depth of the cavity by comparing with the diameter. This feature changed over time. The parts book shows a change from replaceable bushings to vulcanized ones starting with 911 chassis number 307-325 and 912 chassis number 354-938 at the end of the 1967 model year. I suspect the dimensions of this cavity changed at that time. Notice, there are some imperfections in the socket left over from welding the body together. I ground these down with my air driven cut-off wheel and a dremmel so the bronze bearing would have a flatter surface to mate against. Then sprayed it with a zinc rich primer. |
