Transfer Case making fluid - Competition Diesel.Com

Mudn_1 · 07-16-2017, 10:36 PM

So...i did a 47re swap on my 95' single cab. I swapped inputs into the transfer case. It now makes fluid quickly. I have since swapped both trans output seal and transfer input shaft seal. There are no leaks between trans and transfer case, but in 90 miles I drained roughly a gallon of fluid out of the t-case from the fill hole. Does anyone have some insight on exactly how to diagnose what is causing this?

My thought would be the head gear isn't the correct one or something of that nature. Any insight on the matter Is appreciated.

I know when I did my 271 swap my input shaft is the correct diameter but is just too short to reach the seal in the output of the trans. Are you using a trans and T case that were originally together? Verify the seal fit tight on the t case input before installing into the trans?

I checked the Seal before I installed. I even checked depth to make sure we were protruding the seal... I just dont get it...

If someone has a DLD for a 47re, I would like to try it?

Did the new input have the pocket bearing/cap in it? When I did my auto swap that was over looked and I was draining several extra quarts of at out of the transfer case to.

I didn't replace it I don't think. So, you are saying I need to replace that bearing?

That one goes inside the housing or inside the input itself?

The input shaft itself on the transfer case. I had to swap mine over when upgrading input shaft on t-case.

Hmmm.. I bet that is it... Do you know the part number needed? or exactly what it is called from transtar?

It's a pilot bearing. Not sure which transfer case you have.

Click on this link, look up your transfer case model, find the exploded view and associated part number for the pilot bearing.

Good deal. That should take care of your problem.

okie18 · 07-19-2017, 09:46 PM

Looks like y'all got it figured it out before I got back lol

Mudn_1 · 07-20-2017, 08:39 AM

I never would have known that stupid bearing was in there. Thanks yall for all the help! I'll get it out this weekend hopefully.

okie18 · 07-20-2017, 10:26 PM

No problem. I chased it for a week before I figured out what it was lol. It's one of those lesson learned things haha
