Tracy,
I picked up the resurfaced assembly today, and the machinist told me that one end to the other of the gear box contact surface was .027 off.
I removed the original automatic transmission gear box from the bellhousing and replaced it with my new mounting plate. So everything was centered as the original transmission gear box. All the mounting bolt holes were match drilled. With the extra long shaft, .027 will give quite difference at both ends of the shaft.
I don't see anything else to check?

Input shaft
Buly, got your input shaft today and checked it out. The thrust bearing rollers & races look a little stressed but the roller cage has been completely trashed. I do not think the .005" out of flatness on your bellhousing would explain this and the odd wear pattern on the plate. The marks and discoloration (heat) on the bearing and shaft look as if there is misalignment between the E-shaft and the gear drive. When you built the plate & bellhousing adapter for the drive, how did you verify concentricity? This is much harder to do than verifying the parallelism of the bellhousing and plate but is absolutely vital. There is no question that the drive would have soon failed if you had continued to run it. Glad this showed up before flight.
Tracy (Happy to hear that Dave L. is safe! Good flying. )
