Thanks Jeff, will stick with the red assembly lube I'm using then. Plan to run mt 90 in it, kind of expensive stuff, but doesn't take a whole lot. Getting close, got the front output shaft endplay set up last night, want to install the rear output assembly and make sure the intermediate gear is going to drop in ok before I start sealing everything up.

Fwiw the offset keeps the transfer case from popping out of gear.

Those ain't offsets on the rear output shaft, the teeth measure about .030 thinner on the worn side, and fairly even on both sides of the teeth. Picture is of a brandy new aa heavy duty output shaft with no wear yet. No offsets there.

Fwiw, I guess aa is not making them to Dana spec then.

Bummer

jb conversions, very faint to see but they have the tits, but could be an old photo, a call would be needed to confirm







Looks like all the aftermarket shafts are missing the tits.




Here is a tear down and you can see them here.




I sure hope your case does not pop out of gear.

Nice pics Craig. I actually found a new Dana front output shaft that has the tits. I'm twin sticking it, and have installed heavy duty detent springs, so hopefully it won't be popping out.

I've been considering a twin-stick conversion for some time but I haven't yet come across the "perfect" method of dealing with the shiftrails and interlock pills. I'm curious as to how you plan to set this up. This video here: http://www.youtube.com/watch?v=pgfon99zc5c Looks interesting.

Hi lou, I'm not too hardcore so probably not going to be doing any front wheel digs. I'm basically going for easier shifting, and a little more flexibility, like having 2 low without having to unlock the hubs. If I don't like the twins, the original will go right back in. Not running humongous tires, so not too worried about breaking things.

We're on the same page greg. My primary interest is in a 2 low rear as you said. I'd also like to make shifting from low to high with my automatic trans easier. Oft times I find it easier to shut the engine off and shift as I roll slowly. Otherwise I always seem to either rattle teeth in the transfer case or against the parking pawl. I'll keep and eye on your project. I like your detail.

For the d20.

( if you are going to do the entire overhaul, you will want a "master" kit which includes a new intermediate shaft...for that you need to specify which diameter shaft the case has in it now. That is easily "measured" by looking at the end of the shaft now where it protrudes from the case and taking a nominal od. Since that one if original is a very early unit, it could have a 1-1/8" intermediate shaft. Otherwise it will be 1-1/4" so it's a pretty easy eyeball deal. )

I have a 1972 and the output shafts where the yokes are have 10 splines. I believe I measured the right spot of the intermediate shaft where I can see it on the front of the case. It measured 1-3/16" if it was the correct spot.

I probably don't have the right spot.

Can someone produce a picture of the actual transfer case showing where I am supposed to measure?

Thank you

Just an fyi:
looking back over the this post, I noticed that grease was used for assembly. While that is not a big issue, the issue is grease contains soap and could cause foaming. I had this issue with my case and found that I just needed to change the oil. My issue was the oil was coming out the vent tube more then it should.

That's not really grease, it's redline assembly lube made for engines, had some laying around so decided to use it. Also just to add fuel to the what lube to use in the d300 transfer case fire, attached the specs from the 1980 Scout Dana 300 manual sae20-30. Sounds like engine oil to me.

I believe the 30 is a reference to quantity as in ounces of the 20w oil.

All good stuff. Not sure whats in assy lube. I know Jeff uses something that was red is color. Well at least saw something he used years ago. I talked with the guy that put my NP205 reduction box together and he said he used grease.

I just posted it just in case you had vent tube puking issues. Knowing the fix was just a an oil change away.

Default Re: Dana/Spicer Transfer Case Guapo

Have question about the t19 bull gear supplied with Dana 300 tera low kit. The splined hub on terra low bull gear is .070" shorter than the stock Dana 300 splined gear hub. When installed on the t19 output shaft, the stock gear hub extends past the splines on the output shaft, so when the retaining nut and washer are tightened onto the output shaft, the gear is compressed onto the shaft. The tera low bull gear hub is shorter, so it looks like the retaining washer and nut will hit the splines on the t19 output shaft before the gear is compressed. Has anyone dealt with this, or have any input/advice?

Haven't noticed that before unless it is purposely done to move the gear inline with the rest of the teralo gears. Regardless the way it is will affect the way the rear output is engaged. I would say a phone call to the manufacturer would clear things up. Possibly all that is needed will be a spacer behind the teralo bull gear to get things lined up.
