yep, looks like the adaptor is on the way. There is a bearing in the adaptor, so I wonder if it needs to be a sealed type? It appears that there is some oil drain passages in the casting.
Is there a seal that keeps the atf out of the tailshaft adaptor?
Negative on the gasket between the klune and the tailshaft.
Klune is an advocate of your favorite stuff - rtv. They recommend that between the sections of the unit as well at the output flange. Their preference is for the black stuff though.
I did use the gasket I had on the output flange, however.
If you can measure the bearing journal on the output shaft, for me, I can get the od and figure out what bearing it takes.
Here's the shot of the adapter housing I sent you last night.
The output shaft od is 1.374" where the bearing rides. So the bearing id must be 1.375"??? That is a smaller id than the similar area on both the dodge motorhome and the IH pickall output shafts, so the bearings are not the same like I originally thought.
Looks like the klune input coupling is od ground to mate with the seal you can see inside that Jeep housing shot. I can't quite make out the seal number in that pic, maybe you can with jen's eyes??
No freakin' way I'll use rtv shit on anything as you know, I can't believe those folks do that! They must have never tried to pick all the residue out of a slushbox tranny that failed because of rtv snakes crawlin' around inside and then clogging the filter!!
But even more important...we don't want the end of the klune input coupling to "bottom" on the inner race of the tranny output shaft bearing seen in that pic. That output shaft has to have a bit of floating endplay when in operation so that internally heat expansion does not bind anything and most especially place a tremendous load against the rear of the clutch drum in the area where the drum support on the original transmission is scruud up. That in turn would destroy the case in short order and take out the sprag.
So it appears to me...there should be a proper gasket to serve as a "shim" between the tailhousing adapter and the klune case right there at the interface. This is the same issue with the sii oem tailhousing adapter when fitting up the d20 in stock form, that is why rtv should never be used there, only the correct thickness gasket. Other wise the bull gear bottoms in the output gear and ends up "friction welding" the two parts together (in addition to screeching like a banshee).
We'll have to do some calcs on that gasket thickness and then fab one...no big deal, I have most any thickness gasket paper on hand.
On Monday, I'll be over by archer bros. In eugene. I know he'll have a proper amc/Jeep parts breakout for that bearing and seal by amc or chrysler p/n. Once I have that we can do all the crossing! They used to keep a klune in stock for this app so I'll pick his brain about that.
Man I wish we had all the parts for this in one location for a trial fit since it's a first for both of us...but we'll make it happen anyway. I keep procrastinating about sticking the conversion planetary system in the case...guess it's time to go ahead and do it! But if we had the bearing and seal installed in the Jeep housing, and then snugged the klune up to it and then stuck the planetary assembly down in the case, making the calc for any end play allowance would be dirt simple for determining gasket thickness.
The output shaft bearing should not be a "sealed" bearing at all. It is lubed from atf throwoff on the wet side of that seal, same as found in a Scout II with the "special" bearing. In that respect, it's no different than any other variant of a 727, atf inside the trans.
If the front of the klune is not vented separately where it sticks into the rear of the Jeep adapter, then we'll most likely blow a light coat of some sort of "preservative" on all surfaces since no doubt over time some corrosion could form due to condensation. Or...we could vent that area also. We can use something like "boeshield" which I have on hand, or crc sp 400, you prolly have that stuff on the bearing bench!
