As I read in my 1962 Factory Service manual, in the ENGINE section, under "DISTRIBUTOR DRIVE SHAFT BUSHINGS". It says as follows: __________________________________________________________ "INSTALLATION OF DISTRIBUTOR DRIVE SHAFT BUSHINGS" (1) Slide a new bushing over the burnishing end of Tool C-3053 and insert the tool bushing into the bore, as shown in Figure 35. (2) Drive the bushing and tool into position, using a soft hammer. (3) As the burnisher is pulled through the bushing by tightening the puller nut, the bushing is expanded tight in the block and burnished to the correct size, as shown in figure 36. DO NOT REAM THIS BUSHING. _____________________________________________________________ As for where to get this C-3053 tool, I haven't a clue. Perhaps Warren Anderson can tell us as he indicates that he burnishes them when he replaces them.

What did you use to burnish the bearing, and is there any down side to not doing the burnishing? Bill Huff I pull the distributor, and check for excessive side play in the shaft and pull it out and see if the shaft shows wear just below the gear and if so, replace the shaft at the same time the bushing is replaced and burnished.
