Even the new Boge is limited by cost to being only "so-so" when it comes to precision. Since the bearing is pressed into a "stamped" metal cup it can only be so good.

This pic shows a mount in the lathe and me "touching-off" for depth and width. From here I will center the bore perfectly within the cup and on-axis with the bearing and the shock absorbers threaded shaft. I will also make the bottom a perfect machined "flat" mating surface for the bearing to sit "full-contact" against when pressed into place. As you'll see in some up-coming pics these parts are nowhere near flat nor is the hole even close to being concentric within the mount.

While this is beyond the abilities of most DIY'ers it can pay HUGE dividends in mount/bearing performance and life. This is the "only" way to achieve the kind of life associated with "lifetime guaranteed" parts.

As you can see in this pic the only places the bearing would make contact with its seat is around the outside edge and on the part where paint has been machined off. Anywhere on the seat where green paint remains would have a gap between the bearing mating surface and the painted mount stamped seat.

You can see the 6 protruding dimples in this pic that retain the bearing which can now be seated deeper and with full surface contact with cup floor. The dimples are not removed or compromised in any way with this process as all maching is done below them.

More tomorrow...
