Quoted from dasvis:
Nice write up, thanks
Thanks. I have a correction in instructions that need attention. If you decided to use this replacement pivot please be advised as follows:
Be aware that Stern was not all that precise on how parts were located on the play field. Position the replacement pivot with the one hole that I highlighted as being the only hole that matches the original pivot. When you proceed to line up the replacement pivot, try as much as you can to align the replacement on the same angle as the original.
When I was doing my repair yesterday on my Nine Ball, I filled to two original holes and drilled two new holes. However, I lined the pivot shaft to be perpendicular to the cutout in the play field instead of matching the original imprecise alignment from the factory. The result was that I now had to relocate the coil bracket (drill 3 new holes). I felt this was my only option because I did not want to realign the new pivot which would have met plugging the new two holes I had drilled and drilling another two holes.
