Hello,

 I have searched this part as used locally - to no avail. I need to buy a
 new one.

 Is this the right one, the same as used on RD-1C ?
 http://www.ctpowertrain.com/servlet/the-239/C6-E4OD-4R100-NEW/Detail
 I think this rear unit was 3.17, not 2.85 as in RD-1C (front?)

 I know that this part code topic is discussed before - just that I moved
 and don't have access to newsletter archives just now. Please bear with
 me :)

 Cheers,
 Petri

 That looks like the rear planet carrier.
 That rear planet carrier will give you 3.17 for the same
 direction in and out. Ring gear held stationary.

 What I think you want is the front planet carrier. 2.85:1 same
 rotation direction for in and out. Ring gear held stationary.

 Petri, Search words "planet set"  on e-bay will bring up a some with free
 shipping.  You want Ford F250/F350 super duty truck or any E4OD with six
 pinions in the planetary. Make sure to get the sun gear and ring gear with
 the planetary as a matched set. There is contact info for "performance
 parts"
 available in the see other items link. I see them as low as $37.50 from
 this
 vender. The front planetary is 2.85 to 1, rear is 3.17, transfer case is
 2.72 to 1.   If you need the mainshaft or a hub just send a "note to
 seller"
 or you could get the entire gear set and shafts also listed from the same
 vendor. JEGS speed parts has listed the 6 pinion E4OD at about $126 new a
 few months ago.

Thanks Paul and George.

I bit of resent the idea of destructing a perfectly usable planet... :)
but it seems there is no other way. [Remember Alderaan ;]

Actually, what I need is planet bearing dimensions.
They cannot be measured until all six shrunk-pressed shafts are drilled
loose. I need to know those dimensions, because in scientific text,
"sofar, it has worked ok" just won't do. (yes, this is intended to be my
thesis work...)

After done, there is a fighting chance to estimate probable power/rpm
limits of this part - Which forms the basis for all the subsequent work
with my PSRU study. Namely, if it seems that E4OD 6-pinion can be made
to work eg. 1000 hours on 99.99% probability at 500 hp cruise, there is
no need to mess around with custom parts fabrication... which would be a
great relief to anyone trying to make a PSRU for +300 hp engine.

Cheers,
Petri


I have a front pinion carrier right here. Shaft diameter is .455" or
about 11.56 mm. The pinion shaft circle dia. is 2.97" + .455"

Here are some ideas for you. Needle bearings are a lot cheaper
and a lot lighter than ball. It is all about load path.

What 3D program are you using? I can send some of these dwg's in
.stp, .igs or .dxf format.
