The splined plate is made from  part 675 in this dwg I think but
    I could   be wrong.   You might want to get one and find out. I'll
    see if I can get one when I   come   back from Reno if you can wait.
    I think Tracy adds a short cylinder  to act   as   a pilot in the
    eshaft.  I know it is not a stock manual transmission   clutch
    spline. The 2.85:1 planetary gear set is part number 582 and the sun
    gear   is   612. Ring gear is 592.

      The 675 center shaft appears to be the only thing that the forward
     planet
      can ride on. So without seeing it, the back side of it must have the
     female
      splines. The brown part you drew shows the end removed but I am
    not  sure why   sense I have never seen Tracy's unit on the bench.

      Discussion has been made about creating a lighter psru. It
    would'nt  bother   me to begin to work on getting this done. If all
    it is' is getting  lighter   smaller bearing assemblies for front
    and rear, then we just need to  create a   new housing to hold it all.

      Where do I go to get the parts? Is Makco the place? I have a lot
    of   transmission shops nearby, that is why it only cost me $75 to
rebuild
     my MPV
      Ford transmission clutch basket assembly. I have a 6 pinion planet
     set saved
      on my ebay page. I just don't know about the rest of it.

      Ed Carver

     Here's some ebay items for the center shaft:








      Hi Ed;
     There are several versions of that C6/E4OD/4R100 center shaft.
     At least 1 version has a center pilot extension on the splined end.

     The ones I have seen have a large bored cavity in the non-splined end
     (red in the image)
     I don't believe there is enough material to add a sun gear,
     although I have not checked the specific sun gear part you are
    considering.

     I'm guessing Tracy has his shafts custom made with the correct spline.

     Cheers
     Cary

     Not custom made. Some part from some automatic.

     Paul Lamar


    I'm gonna search for the correct part. A few clues as to where would
help.
    I'm not sure what the part looks like. I could use a spline count,
    diameter,
    and other  features of the part.

    Ed Carver

    The spline is 1 inch OD with 31 teeth. It is most likely 675 and it
mates
    with 555 or 554 in the Makco jpg. If you print this jpg and take it to
an
    auto tx shop
    they can probably verify. Part 61 in the Slauson E4OD jpg.
    The male part is part number 420 in the Slauson E4OD jpg.
    Each company has a different numbering system. Sometimes the parts
    are shown stand alone and some times they are shown snapped ringed to a
    mating
    part. Just so you can be confused.


    Paul Lamar


    It appears from the makco chart that 580 and 590 join at the base of
675.
    What puzzles me is the image of the brown part of the damper plate
assm.
   in
    your rhino rendering showing internal splines, with no pilot shaft. I
   guess
    this means Tracy cut the splined extension off, thereby opening it for
the
    shaft from the planet with pilot extension.

    It is confusing if you hav'nt seen one before. I'll visit the trans
shop
   on
    monday, or go to PYP for a one day e40d trans class, and just take the
    whole
    thing apart.

    Ed Carver

    Well I just did not draw it in. It is on every part that Tracy shipped.
    It pilots in the end of the e-shaft. It would be great if you can find
    one. I have two of Tracy's boxes in the hangar. One belongs to Milo
    and the other is in the RV4. I would rather not take them apart.

    Paul Lamar


   I visited Freddies trans shop here in Sun Valley, and was shown all of
the
   e40d/4r100 #675 center shaft part numbers for these trans. Non of them
have
   splines in the inner bore. Must be another trans. I asked the parts
expert
   there and he could recall there being anything like I described on any
   trans
   of any make.

   This part is supposed to be the receiver for the primary planet gear
shaft.
   As you have drawn it, the planet shaft passes through it and pilots in
the
   e-shaft, not the other way around. The 675 part looks like it could
extend
   from the flex plate, on into the back of the planet in the reduction
unit.
   That is how it appears in the parts schematic. However, there appears to
be
   a reversal of the shafts on the current design.

   Ed Carver


   This is Tracy's design. He is not using it the same way it is
   used in the transmission. The parts chosen just happen to fit his needs
   for an input shaft.

   Did the mechanic you showed the E4OD pdf to deny it was a dwg
   of the E4OD parts?

   Paul Lamar


 The fellow handled the parts cashe for a large trans shop. He has the same
 catalog  as shown in the pdf, but also has images of all of the same part
as
 modified over the years. We both looked at the 4 different versions of the
 part, he claimed non of them were broached for splines. He would have
gladly
 sold me any of the designs of the part. We looked at other possible
 contenders within the trans, non of them have the wide base, although one
 did have internal splines. I asked him if any of the E40D transmissions
were
 used in the 70s, He said 89 up. Perhaps it is an earlier ford trans part.

 I am wondering if I am not on the same page with you on this. Part 675 has
a
 splined end. Your rhino drawing of the brown part that is to be drilled
for
 rivits, shows the splined end removed. One of the jpgs also shows the end
of
 it cut off, making room for the shaft that extends from the planet assm.

 Maybe we can get the part, and have it broached ourselves. It is a common
 spline. I could start searching through transmission parts schematics for
 the actual part.

 Ed Carver

 The one that gets drilled for rivets has  a drum attached.
 Jean Proudhome sent me the picture. The drum must be cut off.
 It does not look like it is in the 5R110W pdf.
 It looks like part 554 in the Makco E4OD pdf.

 Paul The part i ordered was from Slauson page 2-10 on his catalogue part
no
 EED61A drum forward, and the eshaft part 420 on his catalogue page
2-10,The
 inside diameter of the big side drum they have spline but it have to come
 off,when i cut the drum flush and  i did,t let a little ridge but  i will
 have to let one if i locate the spline plate behind the damper plate for
 aligment same as shown on Tracy one, it cost me $29.03 from Slauson so
it's
 not expensive the only problem is hard to machine only with very small cut
 the pce is semi temper

Hello Paul,

I have an as yet unassembled psru.  Would it help to have photos of each
component part?

William Hagood

That will  help.

Paul Lamar


It would help a lot. I think I have it sorted out. If you can, take out the
snap ring that holds the ring gear onto the hub. I would really like to see
how the whole assembly strings together until it fits on the flex plate. So
if you can photograph it all put together, but without the housing and prop
shaft. I would like to know what the sun gear bearings ride on.

Thanks for the help William!

Ed Carver

It will be awhile Ed. Im at Reno.
