Oh man TrackSpeeder, you are RIGHT THERE with the suggestion (see below)...
**********************************************
I talked to the parts guy 40 miles up the coast about this binding of the Input Shaft- He sold me the billet one, so he
has some interest in what I am doing, ha. I described to him what the problem was, as I put the Front Pump on, as
the bolts got tightened the Input Shaft LOCKED, and I mean
LOCKED in place, I couldn't take it out, not even
with Vice Grips and a soft hammer
I also described how I minimized the stack,
only putting in the essentials, NO frictions/steels/plates, and NO Overdrive Cylinder.
Basically none of the parts not having to do with "axial" movement and the axial tolerance.
Mike suggested looking at the Center Support Bearing. He said there was a small chance that it could be mis-matched, he's seen
that happen before (the hub and overdrive shaft are made as a matched set.) In
very rare cases, the mis-match can cause a
bind, but he said it was a very rare thing in 37 years of doing transmissions...

I had two Overdrive Stub Shafts, one I bought and one that I got in the original tranny purchase (wasn't sure if I could trust it.)
The new one is on the left, I mic'd them and measured them, checked/compared their bearing land positions and they were spot
on. Still, I did see that there was a (non-critical) chamfer on both stubs (burned area, poss. heat treated) and that chamfer was
smaller on the new stub shaft. This should not matter but maybe there was some magical thing I did not see here and I swapped
out the compliment Support Hub as well (gotta get another new gasket for it now
)
(In the above picture I noticed I had the Torrington still on the new stub, it was transferred over to the old stub shaft for the fit test)

Again, another mock up to check...
...I put the Front Pump on and started tightening the bolts- and ALREADY, the Input Shaft was locked in place!!!
But, maybe I needed to SEAT the Pump down real good, forcing it to align proper- so I torqued it to spec. NOPE

...........................................* SPECIAL NOTE TO THOSE THINKING OF DOING THEIR OWN E4OD *...........................................
You will find a lot of posts showing teardown/rebuild/reassembly of the E4OD's. What I am trying to depict (and this is true, real
**** happening here,) is how much toil you will undoubtedly encounter. Stuff is gonna hit the fan, you will get balls-deep in this
project, have a lot of money invested, and suddenly you will be faced with what seems like an impossible problem with NO SOLUTION
and no one with a big red cape is gonna come down and save you. It's gonna SUCK some times. But guess what, IT'S A MACHINE, it
will be made right, and making it right will NOT happen unless you keep trying. I think that's called learning... ...keep going, ask, try.

I tried Mike's suggestion, I pinned my hopes on it-
didn't work. Sitting there, I look over at the pile of discarded parts and the OLD Front
Pump jumps out at me. At the start of the build, it was an E9 (1989) so I dismissed it, now I realize it can be modified to work fairly well
though not as well as an F5 or F8. It was dirty/rusted/painted, but I wiped it off and started the mock up.

This time IT WORKED!!! (TrackSpeeder was pretty much onto this one...
)

Still, I CANNOT TURN the Input Shaft by hand (don't really expect to) but it slides right out.
I put the original Input Shaft in (longer/used)

And it slid out so easy that I think it would fall out if I tipped the transmission over

(Two fingers, blur shot, no resistance)
I put a Vice-Grip on the OLD Input Shaft and could almost turn it, kinda, I could get a little click out of the guts behind the Center Support.
WITHOUT the Front Pump on, I CAN turn the Input Shaft by hand, just a note.
The new Billet Shaft is "tighter" but can still be slid out, so I am not over concerned about it so far. I just hope another Front Pump will act
like the old one.

(Everything behind the Center Support is fully installed, as it has NO relevance to the stuff in front of the Center Support, as far as binding
the Input is concerned.) Here's a look at the stuff I had left out during this mock up (saves a ton of time, reduces the number of questionable
items.)

*I find it kinda weird that my just tightening down the Front Pump that I cannot turn the Input Shaft, any thoughts? comments?
So I am on the hunt for another Front Pump, and the vendor who supplied me the tweaked F5 will get no mention in the build list, my loss is
his loss.
I plan to swap over the Boost Kit and other goodies I put into the F5.
Wish me luck.
Best regards,
George
