Thanks JFP, I am going to make something using the leftover 2" exhaust pipe that I used for my puller.
My next decision is whether to pull the outer seal off the bearing. I am leaning towards removing it.
The options that I see are:
1) Leave the seal in place and hope for the best. This would probably be fine for the time I will own the car, given my age and the kilometrage that I do each year. What I don't like about this option is that the original problem with the bearing is not addressed. There is the possibility of a low mileage failure as seen occasionally when the Boxster was new and eventually the grease will be washed out of the bearing and a later failure is a possibility. The original bearing was still functioning at 144587 Km (89842 mi) but the lack of lubrication that I saw when I removed the seal worries me.
2) Leave the seal in place and then remove the seal the next time that the clutch is changed. Again this would probably be fine for me, the clutch that will be on the car when the engine is reinstalled will likely outlast me.
3) Remove the seal and make the bearing oil lubricated from the beginning. The only downside to this is the possibility that little pieces of metal or plastic that are present in the oil might find their way into the bearing. Oil filters that I have inspected since I bought the car have always been clean. What I like about this option is that it solves the underlying problem with this bearing, i.e. - over time the grease is washed out of the bearing and it is under lubricated.
For my peace of mind option 3 is likely the best, I like the idea of the new bearing running in a nice warm oil bath.
There is a fourth option...
4) I am over thinking this!
