Cockroach,
The parts I received parts. Their ID is .15mm under sized. When I press them together I measuree 125 lbf. So your 113 lbf was a good calculation.

Cockroach,
Thanks again for the posts. I plan to dig through my work and find the source of my error the next time I have a spare minute.
This has been fun. It has been a while since I have worked on a problem like this. Reminds me of school.
At my place of work we had some press fits that...
Still tinkering.
Does anyone see something that I am missing?

Cockroach,
I have just found the time to return to this problem and I am still not calculating a reasonable answer. Although it is better then what I was calculating since, Thanks to you, I realized that I should be using the yield strength.
Could you possibly point me in the right direction...
Cockroach,
Thanks for the time you spent on working this out. I am currently reviewing my work to figure out where I went wrong.
Your answer is more appropriate than what I was calculating.
Thanks again!,

Thanks Pud for the fast reply:)
I will research what you pointed out about the isochronous creep curves.
I should have also mentioned that the hub will be submerged in gasoline.
Would you suggest a specific elastomer?
Thanks!

If I have a hub made of Celcon M140, with an OD 14.00 mm, and an E of 2500 Mpa
A shaft made of Aluminum T6 6061, OD 9.2mm, ID 7.36mm, Length 10.00 mm
I need to figure out the interference needed to accomplish the following:
A press fit...
