This clam shell you mention, is it one of the adapter plates for the press? If I were to rent a larger press, would the bearings go right on? Will the same press do the removal as well? Will one of the bench top presses work? How long of a stroke will it neeed? Maybe you can insert a picture of a good press to use and I will see if the rental shop has one. Thanks.
As far as the transmission goes, It would be great to know how to rebuild one correctly since they are notorious for howling. I'll keep looking into that. Worst case, I just get a core to experiment on.
