NP205 Questions

[tonkota]

Is this a good case for a Pig? What about the center output? Is that ok? Could it be changed to an offset output?

Next question:

WTF is a doubler? Do they just bolt two t-cases together? Could I bolt the 205 infront of the 3 spd case? That would make the 3 spd case voulnerable to breaking right?

 

[usmcruiser]

I dont know if it is a good candidat for a pig I can only assume that it is. Strong, potental for twin stick. I dont think it can be changed to an offset output, but I am no expert.

Doubler.

205s have a few great features:
super sturdy
easy to convert to twinn stick
adaptable for doubler setups
easy to locate
fairly cheap
good parts availability
bad points:
weight
only avail in 2:1 low range (wagner machine is working on 3:1s)
can not change output to offset

i think you would be better off with a split case. plenty strong, geared low and proper outputs.
the 205s can be doubled up behind the grb (gear reduction box) from a 203 t-case by using one of a handful of doubler adapter kits available. do a search on pirate and you'll find lots of info in the general and chevy forums.

Yep yep,

weight, it is iron and currently the factory strongest case. LOL

reports say it can be converted to offset output, with np200 pieces, I havent had time to play yet so i do not know for sure.

 

[orangefj45]

yeah, i've heard rumors about the 200 outputs being compatible but have not seen one in person or pics of one done.

Thanks for the information guys. I bought a SM465 and it came with a 205 case. The doubler stuff looks too pricey for my budget wheeling!! Wow though.

203-205 doublers
Source your own parts, and do it yourself! cheap cheap
i think i can sleep walk through these now.

OR let me know what your looking for??? LOL

I have a ton of 205s and was suppose to be sent three np200s but none have
shown up yet for me to play with. I would like to just to see if it works, but i read
and have been told it can.

on the 465 to 205, pull them apart check the wear on the output, collar and input before using.

weight depending on adapter they are right around 150-175, read somewhere that one weighs 190 but i never had one that weighed that much yet.

Sorry if this is common knowledge but I am not familliar with american drivelines. Which american t-case, if any, is offset to the right like the cruiser t-cases? I like the idea of the NP200 parts for NP205 conversion to offset, but do you think it would weaken the t-case at all?

cheaper than the jed's machine adapter?! where are you gonna get the adapter itself? how about the shaft?

i think some of the early jeep stuff was offset, but those cases are not very strong at all. don't quote me on that either. not sure.

The Dana 18 used in old Scouts and Jeeps was offset and Twin sticked from the factory. This is also a cast iron gear case so strenght shouldn't be an issue, but I remeber correctly the low range ratio was 2.46:1.


here is a link to check out!

[orangefj45]

it's not the case that's weak, the gears suck.

 

[HI^C]

d18 have case problems, but all the guts fit into a d20 case. I have seen them take a pretty good beating and not break, but they are smaller inputs and outputs then the np205


Np200 is also a offset rear, funny looking, alot of people that take these out just throw them away, that is why i was getting them for next to nothing. but they are not here.

 

[Niner]

Jeep quadra trac was also offset but a POS full time chain junk.

http://www.novak-adapt.com/knowledge/model_18.htm 2.26:1 low

not a great case, but stronger than a stock 40 case for sure....internals are largely interchangable with the D20 cases too. believe there is a 4:1, check the link....


IMO, wagons and doublers are a poor idea....lotsa gearing and lotsa weight = lotsa potential breakge, particularly if you play in the rocks. Enuf people are breaking stock rear shafts in 40's....

see http://www.marlincrawler.com for doubler needs...also, the tech links cover some other options including the 203/205 and others.

My opinion, the 205 is one hella strong case, but is also heavy as hell, long, etc...there are other better choices out there, but it all depends on where you plan to go design-wise with the rig...

 

[Niner]

Hey Woody thats the same link I found

 

[orangefj45]

i had a larger dana case a couple of months ago, could have sworn it was a 24 or 28. not the one in the 4wd aerostars but a cast iron case. it had centered and offset rear outputs.

I thought some of the duece and a halfs had t-cases like that to drive the tandom rear axles?

 

[orangefj45]

yeah. those are the bigger rockwell cases. most of them are air shifted.

the dana i had was almost the same size as a 205.

"cheaper than the jed's machine adapter?! where are you gonna get the adapter itself? how about the shaft?"

YEP and YEP.

but that is not really what i was talking about but you could. I am just saying find all the other parts on you own, dont go through a mickey mouse company to purchase parts from. OR like i just witness on the famous MORON'S of (e) BAY pay five times the value for one single piece, or over twice what something just sold for less then three days ago. DONT BE LAZY, source your own stuff. TO keep costs down. If time and $$$ are not a factor then by all means spend the money, and i might be the one selling you the parts, LOL bid more $$$!

Jedi s i had to use in a rush job (1.5week doubler), little rough for a finished piece, thinner plates then i am used to, WMS is 3/4", shaft was rough and needed to be finished as well. still using the alum bearing retainer which i cannot stand! but a most still are. I do like steel rather then bling$broke or light crap.

These things are not rocket science, soon as i get time to sit with my cad whore to finish up my plates i will be doing my own. ( whenever that is) I can get shafts done right now.

dana? did it look like a big triangle? sounds like the smaller rockwell t case in early chevys (married and divorced). they did make a divorced dana 20, married and divorced dana 21 ( single speed case) dont know of any larger dana cases? What side drop? d28 is alumn case chain

205 to lc case (approx)

1.5" longer
1" wider
1" taller
5 to 20 times stronger, LOL
30 lbs more? havent weighed a lc case

currently there is no case close, and everyone is trying to imitate parts.
$ to $ it doesnt make sense to do anything else. Gearing is something
to be desired, but thats really it.
