t-case cone seal

[bryanjeep]

HI, I sprung another leak at the tailhousing of my t case i think. I know how to take out the driveshaft, but is it hard to take that housing off? Is it only going to be removing the bolts? What kind of sealant do I use?

 

[PASmokeater]

all it is is the bolts and a gasket. Spray some PB Blaster on it, let it sit for a night then have at it. There are tons of oils out there, and I to am curious as to what the guys will recomend. We will have to see together.

Remove the 3 bolts holding the tailshaft housing on, then pry it off carefully. Pry the seal out, don't worry about ruining it. Clean it up and you'll find some numbers on the metal part of the seal. The parts store can cross reference these numbers. Best to take the tailshaft housing and the yoke with you to make sure the seal is right the first time.

I slip the new seal in the freezer for a few minutes, then install it with a little RTV silicone around the surface the contacts the tailshaft housing. Use RTV when reinstalling the tailshaft housing.

How much do you think this part is? Is it a normally stoicked item? What RTV would you recommend on that one?

 

[Snitty]

its a simple seal... stuff like that is always cheap... as far as rtv, i'm not sure really... i always use red stuff

Try O' Riely's for the seal. I find that the ultra bond works better for sealant. If they don't have the seal e-mail me. I know someone in Kenner that will have it. If you need help let me know.

Why does the t case take ATF instead of gear oil?

 

[Snitty]

i think it has to do with the style of gearing in it... or the chain perhaps

What is this seal called?

 

[Bounty__Hunter]

Transfer case tailshaft seal.

Clean up the old seal after removal, there will be a stamped number in the metal they can use to get you the correct part. My local Napa had it in stock, most auto stores should.

 

[bryanjeep]

Is that seal callled the oil pump housing seal?

 

[Bounty__Hunter]

No.

Why does the t case take ATF instead of gear oil?

In the early 80´s, I had the same guestion, back in the days of surface mail. I wrote New Process (Dodge/Chrsyler) with the same question. They sent me a really nice tech., history book and several letters.
The gist of it was, due to the mandated, fleet mileage goals. They changed to ATF, because it caused less drag, i.e. better mileage.
Used to be permissable, to change back to GO (gear oil) 90, if the customer complained about noise in the geat box.
Most newer transfers, are designed to work with ATF, don´t know if the change back to GO 80-90 is still permissable, or advisable. Probably wouldn´t hurt a straight gear and chain type box (command trac), might mess with a box with clutches (selec trak). Don´t really know for sure. Maybe it´s time for an E-mail to NP.

one other thing to point out...if you have a slip joint eliminator kit on you might want to take some clear silicone sealant and put a single fingers worth onto the out put shaft before you slip the yoke back on to seal the splines.
I had a small bit leak from my slip yoke elim kit along the spline when I had my jeep at a steep incline.

Thanks for the tip, UJ, I'll have to remember that when I do my homebrew SYE.
