Sealing d35 pig to beam?

[atvkid4eva]

hey guys, i was wondering what the best sealant was to seal the d35 chunk to the beam? and whats the best technique for doing so as far as letting the sealant dry some before being applied? thanks -Bobby

What i do is put rtv blue goo on myne and just try to be careful putting it up and not smearing it all over hell.tighten the bolts and let it sit 3-4 hours before adding oil or running it.worked for me!

ok, i was just wondering if there is a certain color rtv that works better than others...and ive heard that your supposed to let it set up some before applying the two surfaces?

man i put a new dana 28 in myne 2 days ago and evenly put a thick paste of rtv blue around the outer edge of the d28.(make sure u clean both surfaces real good with some small grit sand paper or use a wire wheel)i waited about 5-10 minutes then slapped it in there.i tightened the bolts criss cross makin sure not to smash all the rtv on one side also.I waited 2-3 hours man and put gear oil in it and ran it straight around 45 miles and came back home and checked it again and the fluid was fine as well as the seal.

I used red high temp rtv on mine. Be sure you don't smear the hell out of it. And put about a 1/4 bead all around.

Let it tack up a bit then plop it on there. It's really better if you have 2 people. one to hold the chunk up to the beam while the other is on the other side to thread the bolts in and snug them up.

I've always used the Black RTV. It's supposedly made specifically for differentials (gear oil immersion). Ford I know used red stuff though, so it probably doesn't matter a whole lot which one you use.

Everything I've seen from ford is usually black.

We use the gray a lot at work. Works very very well. I have never in my life waited before assembling for it to set up, or have waited to add the oil to it. Never had a problem.

My D35 had red RTV on it originally. I do recall the 8.8's RTV was black though.

X2 on the red. I've got several axles for spares, all were red when I broke them down.

Really as long as the package specs look like it will handle oil and at least somewhat temps (though really not alot) it'll be fine.

Just about any RTV will be good for a diff seal.

X2 I've never , EVER waited for silicone to set up. Never , EVER waited to add the oil. Never EVER had a leak --- EVER !-- because of it.

X2 on the Ford grey silicone- originally designed for 7.3 diesel, and we call it "diesel grey" . That stuff will seal just about anything. I've even smeared it on the outside of whatever leaking on some of my beaters. It works.

just remember the rvt different colors are different strengths

The only reason I wait for it to tack up a little is to keep it from smearing all over the place. Just for the surface to get a little tacky, not anywhere near setup.

It only takes 5-10 minutes for it to get this way.

got it done tonight...i used the ultra black...seems to have worked great...my buddy owns a mech. shop and he said they always use the black or the greay on diffs...it is recommended for areas that come in contact with oil residue..

Exactly. It is actually a chore to remove a diff cover that has been installed with 7.3 RTV. Excellent stuff.

Every time I've nstalled a TTB diff chunk in an axle "Banjo"
I've had the "Banjo" either resting on a tire or a workbench.

I've applied the RTV to the BEAM as a "bead"
and as a thin film to the diff chunk itself.

I always lower the chunk onto the beam using atleast
four (home made) guide bolts.
