Rear Bearings Retainer

I’m trying to put a dana 18 behind my t14 but bearing retainer is to big do they make a difference retainer for 18 and 20

 

Apparently there are two different sized Dana 18 3 5/8” and 4” is there a an adapter for the smaller d18 ?

 

You will need a big hole (4inch) case. So that the rear output bearing of the T-14 will fit the transfer case bearing bore. A lot of the early dana 18's were small hole cases(had a 3 and 5/32 bearing bore hole). And all the t-14 trans had a 4 inch output bearing.
here is some more info:https://www.thecj2apage.com/forums/forum_posts.asp?TID=43134&OB=DESC

 

The odd part is this is replacing a T86 which uses the large hole case. Did you change the transfer case too?

 

The transfer case is the same

 

No the t86 the transfer case holds the bearing in no retainer

 

Yes, It is odd. if you removed a T-86 the t-14 should bolt up where it was,I would think. study the link I posted above, maybe there is some info in there that will help..

 

The transfer case index's on the transmission of either the T86 or T14. Are you sure it is a T86 and not a T84? Just not sure why you would have a small hole case.
Some-ting funny going on. You show you have a 1966 with a 225 V6. From Novak. https://www.novak-adapt.com/knowledge/transfer-cases/model-18/

Final Civilian, 1966-1971
The "large case" version of the Dana 18 was the most improved version of all. It was only found behind the Buick V6 engine with its T86 and T14 transmissions. The case casting used was that from the Dana 18's progenitor, the Dana Spicer Model 20. This case featured a 4" locating bore and a single stick shifter and new front output cap. The front output assembly did not provision for a shifter mounting point, as the shifter was anchored to a transmission bracket. The internals were essentially identical with the standard Dana 18. This version is best thought of as Dana 18 guts in a Dana 20 shell. Individuals can build a "Super 18" by copying this version.

 

It’s a t86 has the d18 with 3 5/32 hole the bearing is held in by the transfer case no retainer

 

The twin stick transfer case may have been a converted single stick but there is just no way for the T86
to work with the small hole. It may have been a T84 or T90 transmission that you are replacing.

 

This is a picture of a T86 rear output.

 

Don’t know how to upload pictures on side of case says t86AA

 

Your transmission should look like the picture I posted. You can see the tapered section that goes to the transfer case and mounts flush.
What did your T14 come out of?

 

Mine does not look like that I’m standing right next to the transmission it’s a t86AA

 

No I rebuilt the t86 it has t86 gears

 

The top may have been swapped on to a T90. That picture is mine from a 1967 T86.

 

The top is a t90 but the case says t86AA I promise you it has t86 gears I bought the t86 rebuilt kit which has needle bearings in the reverse cluster gear and smaller bearings for the output shaft

 

In the end none of this matters as you will need a large hole transfer case in order to use the T14. Your Jeep started life as a 1959 and there is no telling
what has been done since. Mine is '61 converted to V6.

 

x2, and remember the T-14 has an odd transfer case drive gear with smaller spines, if I remember correctly they have 10 spines, not the standard 6 spline like everything else. This will need to have the correct gear set in the rest of your transfer case to match it.
