Dredging an old thread back up as I'm trying to find some background on underdrive versions. Just stumbled across an older used underdrive to possibly buy. From pictures the attachment of the inner shaft to the planetary gear is different than other versions I have seen. The inner shaft is welded to the gear rather than a splined interface (attahced pic of example of unit like this disassembled on bench). I emailed Ashcroft and Dave wasn't sure this was a solution they had used or if it had been modified after sale at some point. Anyone seen something similar?
