well jack answered my question here after re-reading this thread.
the upper was never dealt with. With the pi pump,
i would go with jack for rebuild.
i may go with a one piece shaft. get rid of that sleeve.
but press a piece of stock over shaft to hold shaft up/,, shaft supported all the way up into main bearing cap.
thinking of using stainless for bushing and shaft
.
No, a one-piece shaft would not work. You'll note even on the Olds conversion, Olds engineers used a two-piece drive.
No, as previously mentioned, don't put stainless in there anywhere. A longer cast iron bushing in the top of the pump is the best bearing material.
Rikki, if you want to add some value to the re-design, use a big block Mopar bronze bushing in the hole in the block where the driveshaft goes through to mate with the distributor.
If anyone is interested, I still have a couple of the re-designed Packard pumps and they work fine on a newly rebuilt engine.
Another FWIW, I bought a pallet-load of Packard V8 parts from a shop in the Chicago area. He had been involved in some oil pump mods and there is a big box full of oil pump bodies, shafts, gears, pickups and vacuum pumps.
Since the popularity of the Olds conversion, I wonder if anyone will ever want any of those parts.
