I would assume one could clock this t-case, if so would I need to buy a new gasket or just make one? I really need to try to improve on my crappy front d-shaft angle.

 

I think you can, but i think that you need a clocking ring machined up in order to do it.

 

What is involved in making a clocking ring? The ones I have seen look like 3/8" flat steel laser cut to fit the t-case pattern.

 

Best be carefull about clocking it because the 208 in pump feed for lubing, not splash like gear Tases that are clocked.

 

Yeah diddo on the pump fed lubrication on the 208's, and yeah the few i've seen made for 205's are just a 3/8-1/2" laser cut steel ring with the approaite holes drilled in it.

 

Since I've never had an NP-208 on a truck before here is a good question for you guys. I am leaking a lil bit of fluid out of the output shaft for the front diff, also you can hear the chain inside of it. I'd imagine that the thing is about ready to die, which I really don't feel like replacing since I just got the truck running. What can I do to fix it up for a while, until I get a good lead on a 205 case and some more shafts?

 

208,s dont have a pump. As far as clocking goes, the bolt holes are all evenly spaced apart, so you could knock out the alignment dowel in the adapter then spin it wherever you want it. I considered this once, but even clocking it down one bolt hole would cause it to hang down pretty low. If a person was careful, and took their time, they could possibly drill a seperate set of holes so the case wouldnt hang quite so low. Drilling 6 new holes might cause some weakening of the aluminum adapter (there are some cast steel ones in the shorter length, but they arent as plentiful as the aluminum ones) I would say your current case is scrap if you can hear the chain. Normally the 208 cracks at the bottom front, right where there is a kind of angle iron looking chunk that protrudes from the case for no apparent reason. There are some 208's that have extra webbing in this area, but ultimately they will crack there too if subjected to lots of torque (like a 420 stroker windsor with a healthy stall converter puts out) I would recommend you find a Borg-Warner 1345 to replace your 208- its a direct bolt in, from the splines and bolt pattern to the driveshafts(unless you have a bronco, then it has a different rear yoke) The 1345 has a stronger case, a wider chain and a lower low range 2.61 vs 2.74. The 1345 was used in 3/4 ton fords in the early to mid 80's. The good thing about the 208 is that they are easy to change and plentiful- around here anyway, but so are 205's

 

And also, if you do change to a 205, your front driveshaft angle will get worse, because the planetary assembly in the 208 or 1345 positions the yokes further back than the will.

 

208s do have a pump. Granted it's not much of one but it does its job.

BW's didn't come out till the mid 80's and were used up through till 96 in the half tons from what i know.

Yeah the front shaft if switching to a 205 will be shortened about 4" depending on the adapters, likewise with the rear, only lenghtened.

 

I still must disagree, the BW cases have a pump, but the NP208 does not. I have had many of them apart and have a plastic crate containing the internal parts from 4 of them I have broken and I dont remember ever seeing a pump.
