A while back I had a thread going and was told that a 3:1 gearset was in the works for the 205. Any news?

It's not happening, due to gear and case dimensions. Best bet is a 203/205 doubler. Use WMS' 3.1:1 203 gearset if super low gearing is desired.

A local old timer up here who used to run Baja has a 205 that he will not part with that is one of seven using a 3 to 1 gearset. His brother built them for his"crew," but he died 3 years ago and there are no blueprints to be found. The first 6 very Chevy's, and his is a Ford 205. It IS possible, And I think someone is working on it. Who is it?

I would love to know!!! I could sell alot of those.....

Quite a while back I spoke with Mr. Obrian of Obrian 4x4 somewhere in CA. He stated he was in the process of makine a new 3 speed tcase and that he was looking at doing lower gears for the 205. I think he is the same one that made the insain lower gear set for the Spicer 18 transfer case.

O'Brians has a 4.86 for the 18...

Honestly, I guess I'm not as concerned about the lower gears as I am about strength. But I would of course, like to know I can get my crawl on in the future. I think it is just silly trying to put that low of a gear and that much stress on a case as small as an 18, 20, or a 300.

Does anybody know if O'Brian, or Obrian or however he spells it has a web site or a phone number. I would like to contack him and find out the status on what he is doing.

Thanks

I can tell you for sure that Tera Low 4:1 gears in Dana 300 are not up the task when used in a 5.0L CJ7 NV4500 4:56 geared ARB F&R 36x12.50x15 TSL and small rocks in Australia.

Tore the teeth right off the gears, we then twisted the rear output shaft off trying to finish the obstacle in Hi range

More pics of the destroyed gears can be seen at

Why the fawk is it so difficult for people to make a lower set? They do it for most other t-cases and those all suck. the 205's only downfall is the 1.91 low. Seems to me they could make ass loads of cash if they just whipped something up that would work.

Apparently there isn't enough clearance in the case nor a way toeasily modify the case to fit the different gears

hahahaha:D

Perhaps that is why noone is doing it

and think of the t-case adapter market.
it would go to hell in a handbasket is the NP205 was worth having.

Oh it's worth having..you just need a bigger motor :)

By the time you paid for the gears, and case mods, you would be 80% to the price of an Atlas II I would think. If it were even possible to do without lowering the strength of the 205.

I have a 205, and i would seriously consider low gears for it of they were available. the reason that they are not, is because you can only get about 3:1 to fit in the case, and you would have to mill some of the steel out of the case to get those to fit, thereby weakening the case. There is NO room in there for bigger gears, sorry...

If you have enought wheel base, do a 203 doubler with the 205. This gets you almost 4:1, strength of a 205 all for ALOT less than the Atlas. :smokin:

do you ever work?

Hell, the only reason I'm on here this early today is cause i already ripped out an old kitchen, and put the new one in already. I figured that was enough work for one day.

My interest in the 205 is basically due to simplicity. My project rig is stuck at the lack of a transfer case option. I dropped a 4.3 and a TH3530 into a Suzuki Sidekick. It now sits on a pair of 35 splined Dana 60's and 38x14.50 SX's. I just cannot decide on a T-case. I want an Atlas, but feel that they are $$$ as well as a little overhyped. I was then considering a 208, 241 and the venerable 205. I just got down to doing some measuring and sadly, the 205 is not an option. It would invade the framerail by 2 inches:( . So, that leaves me with the Toyota T-case, which I already have, but I am unsure of their strength. That, and I gotta cough up $450 just to bolt the damn thing on!:mad:

I will be using the Toy double cases - 4.3L, TH350, Dana 60's and 42's :D


Ask Camo - he runs something similar too.....

just a thought......but couldn't you instead of making the gears bigger, make the intermidiate gear smaller that would have the same effect and there's no worry about a smaller gear not fitting right? ......dunno if it'll work but it's worth the thought and maybe working it out on paper...............:question:

I think the reason they don't consider this is it would compromise strength

Hey if you get anything out of Obrian post it up for the rest of us.

As far as reducing the intermediate gear won't work. Reduce the gear thus reducing the diameter then bad or no contact with your other gears. Only two ways to make the other gears contact increase their diameter (can't case isn't big enough) or move them (simple enough to see the problem here). Good thinking but won't work.

Have you ever even SEEN the inside of a tcase??? I am assuming not...

If you were to make the idler gear smaller, then the drive gears for the front and rear HAVE to be bigger, or else they won't mesh. And you will go no where.

Good thought, but that's just not how it works. Apparently 3:1 is all you can fit...

I will be using the Toy double cases - 4.3L, TH350, Dana 60's and 42's

WHEN???

mnstrfx,
these jeep people prefer to spend thousands on 1 off stuff when the actual solution is on the shelf.
it is one of those jeep things, they dont really get it.
