Look what fordman300 made for me. Is this cool or what????? Its for an NP435. Thanks Cory! Ck. is in the mail.

Hey Cory, can u make an output shaft for a NP205 that won't break?

You can get a 1410 yoke for an NP205 from Spicer. I had to have Cory make this one because nobody makes a 1350 or a 1410 for an NP435 transmission.

i have 2 sitting here that are welded and have a bushing in place of the inner roller bearings. don't guarantee them but they are stronger than stock. i started making one out of billet but it got pushed off the priority list. i also contemplated making one out of a dana 80 pinion shaft but haven't came up with a junk one to try that on. if anyone has one let me know im still interested in that deal. The lower numerical number aka higher gear the better need the bigger diameter pinion gear.

I was talking to a machinist last night about this and he said if I bring him one, he'll see about making one from hardened steel. Now when you said a bushing instead of the roller bearing are you talking about the big bearing behind the yoke? Also I've heard that the oil slot on the rear output shaft is a weak area. When a new shaft is made, does this feature need to be there?

Also, does anyone have a picture of the profab 205 kit with their output shaft?

Here is a parts diagram for a NP205

Alan, I just installed the 205 profab kit, the only usable stock parts are the case a couple of bearings and bearing caps everything else comes from profab and nothing in the kit resembles the 205 stock parts. All gears are straight cut and about 2 1/2" wide, the input shaft is about 2" longer and everything just does fit into the case. The oil slots are weak points but most of mine broke at the small diameter behind the spline, if you are going to have one made this area needs to be larger and go to a 35 spline, instead of slots drill (3) oiling holes about 1/8" in size. As for the 435 trannies a 1410 yoke is available I have one on my tranny it came off of an f-600 with the large shaft. Walt

Walter, I was curious about the profab kit because from what I've heard, if a 205 is gonna break, it will be the rear output shaft that breaks. So I'm thinking why pay for the profab kit if I can just get a stronger output shaft, but I'm curious as to what is different about theirs to make it stronger.

Alan

Alan,
have you changed out the rear bearing retainer???f
It is a big help on these cases

I had a quick question regarding a 1410 series slip yoke. I just had a new intermediate driveshaft made and bought a new slip yoke to accomodate 1350 series joints. Would I be able to get a 1410 series slip yoke to spline up on the driveshaft I just had made, or would a 1410 series slip yoke require different splines??

Alan, Profabs output shaft looks nothing like the stock version, it is made totally different and will no way work with stock 205 parts, the diameters are larger it has the larger 35 spline, an intermediate support ball bearing and support bracket that takes place of the inspection plate. Profabs shafts are made of 4140 alloy, yes your main problem is going to be the stock output shaft, stock helical gears and shifting collar splines are also weak, the helical gears are the cause of breaking bearing retainers they are trying to push the bearing out the back of the case, the input shaft will do the same, I make a billet aluminum bearing retainer to solve the bearing push problem, the profab also eliminates the high side of the transfer, all gears are replaced with straight cut and are 2 1/2” thick, this is a massive kit and well engineered. Walt

The profab kit is a bullet proof piece. You can get a 1480 rear yoke for it to.

i weld up the oil slots completely and replace the needles bearings inside the output shaft with a bronze bushing. im almost positive i could make an output strong enough, out of a dana 80 pinion, to make the weak link the input shaft. but for a married case i don't know how to make that any stronger.

Cory

I am going to be taking out the drive shaft of an F600 next week and I will take out the yoke also of the transmission. To see if it is the same thing. Are you sure it is the same diameter and spline count as a 435 from a 3/4 Ton?

Digger the output shaft is larger in diameter than a pickup NP435. The input is also larger and longer, like we talked about a bit ago. The thing that did not cross my mind is the input shaft can be changed to the input from the pickup version with the only expense being a new gasket for the nosepiece. Just pull the 4 small bolts on the nosepiece and if i remember correctly the input just pops right out. So just put the shaft and nosepiece from your pickup version in the f600 version and then fab a support an it is done.

Does the 205 profab kit give you a choice of ratio's? I can't find anything on their website about it.

So then is there or is there not a 1410 or a 1350 yoke available for my NP435 with out having to change out shafts? I looked through 65 pages of Spicer yokes and could not find anything that would fit my transmission.

No there isn't a choice of ratios. 1.96 only.

Alan

Jarrod,
No the 205 kit has one ratio and one speed.

Travis

Has anyone ever run a Dana 24 t-case?

geesh: this thread sure got the shit hijacked out of it. No wonder we can't keep any thing strait.

Jarrod,

Yes they have a slightly faster ratio i think like a 1.8 something.

Travis

I ran a Dana 24 several years ago, went thru about one a year. I put a 205 in and installed the replacement output shaft that is drilled instead slotted and never broke it. The Dana 24 is a pint size version of the 205 and considerbly weaker, but would be cheap if you could find them. I think I still have one. The secret to long lasting puller drivelines is DEEP gears and of course don't bounce.

i was wondering where you get that rear bearing retainer or do you need to have it made? thanks

Thats very cool digger i can see your going to be a very tuff competitor this year. You gonna be in for Julesburg, CO May 17th?

Digger, Sorry if I confused you on the yokes. No it is not the same as a 3/4 ton 435, like I said earlier and Travis said the output shaft is larger and the input is 1 3/8" in dia. as for yokes you can have any yoke you want, if they don't sell it make it, what ever spline you have take and machine the center out of it saving the spline and leaving approximately .375 - .500 of material thickness, put a 3/16" chamfer on both ends, buy or find used the size (u-joint) yoke you want, machine the center so that your first machined part is a press fit, chamfer both ends 3/16", press the two parts together and tig weld using Ni 99 rod or 308 s.s. Let air cool. I have them on a few trucks including mine and they work just fine. What I did with the tranny was I took the f600 435 inerts because I wanted the large shafts and put them in the 3/4 ton case, the bolt pattern was different between the two cases, I had to machine a little off of the nosepiece so it would fit into the 3/4 ton case, change pilot bearing to fit the large input shaft, and make a 3/4" spacer.

Walt

Alan,
We were breaking the stock 205output shafts about every other pull. We let some people talk us into putting a big shaft and bearing ratainer on the case. Weput 2 pulls on the parts and broke the transfer case, frontend and rear end. After that episode we spent the money on the Profab kit and have never looked back.
