With all the posts about lower gears, I would like to share the approach I am taking with my 45 Truggy project. This past weekend, I finally completed the overhaul and assembly of my doubler setup. Shown below is a pic of my SM465, NP203 and NP205. The NP205 has been modified for twin stick operation and incorporation of an electronic VSS.

The assembly is long -- 37" total, but I doubt many would question its strength.

With 5.89 gears in the diffs, the crawl ratio will be about 155:1 My tires are 42" TSLs

Did I mention this is a real fun project:) :) :)

COOL!!!! looks awesome!

Looks awesome! Plenty bombproof too...

Where did the adpater for the NP203-Np205 come from? I am thinking of a similar setup with a NP203/NP205 behind my NV4500 in my FJ55 crawler project(a bit down the road, timewise)

Medusa,
THAT THING IS GOING TO BE SO COOL!!!!

HURRY UP ON THAT THING!!! :D :D

you are building the dreams of thousands of us!!

That is an Off Road Design, GEN-II adapter.

are you going to use a vortec ??

That is so freaking cool!

I think that is THE option, rether than using a Cruiser T-Case...203/205 is an AWESOME alternative.

Hey man, how much $$$ do you have in adapters? I am very interested in the cost of these only since the other items range so much in price.

I have a total of $1350 invested in all of the gearboxes combined. That figure includes $750 for the ORD 203-205 adapter and $50 for the 465-203 adapter that I purchased from a salvage yard.

In answer to Land Crusher, Yes -- the gear boxes are now sitting behind a 5.7L Vortec:bounce: :bounce: :bounce:

OK

37" from Bellhousing to Output Flange?

That is not bad at ALL...I need to see how long my Atlas/465 is...

hey jack!
looks great!!!!! can't wait to see your rig(s)! think you'll have the 45 truggy done for the 45 run? should be around my B-day, the last weekend in august and we're thinking about doing it at lake alpine, southeast of sacramanto on highway 4.
keep up the great work!;)

Come on! 293/465 adapter in the junkyard! That is the most elusive find ever!

I bet the average person will get theirs at AA!

The funny thing was that I found the adapter (in a scrap pile), but never was able to locate a 203 that was originally mated to a 465. I finally gave up and just bought a 10-spline input gear ($40) and swapped that during the rebuild.

That is because they only adapted them in '74 Blazers I think...very elusive!

Did you happen to see how much it would have cost from AA?

IF YOU HAVEN'T ALREADY /CHECK OUT

they got 3.6:1 gears for the 203
that really makes the doubler a crawl box

Jack, where'd you get the 10-spline input gear? I got a new one at Drivetrain Specialists in Las Vegas, but it was well over $40, IIRC.

BTW,
NICE DRIVETRAIN JACK!

Wowee!

Wazzup Morgan? To answer your question, I have a friend who owns a transmission shop and he gives me good deals on parts. I think I really got a good one on the input gear.;)

Not much here.

I look at that drivetrain and "the gears start turning". I start daydreaming about putting an NP205 behind my 203, then going to a rear 14-bolt and front 60, then finding some sort of monstrous diesel to put in front of the SM465, running 38x14.5 swampers, then it just gets ugly. :)

Hm...

Morgan

I looked FOREVER to find a CHEAP SM465/NP203 adapter and finally ended up getting one for $75 from a tranny shop north of me, Beaverbrook Trans. They were the only shop that seemed to know what I was talking about, and the owner says he does a lot of engine and tranny conversions in 4x4s, if I remember correctly.

It actually scared me when I asked for the adapter and he said, "oh, sure, I've got one". I was thinking, "He'll probably send me a coolant overflow container or something...." Most of the yards I called would say "It's a what? And it goes where? Whaddaya mean transfer case? With bolts? Made of metal? Hmmmm.... Ya don't say."

I got the gear from Drivetrain Direct for $75 or $100 I think, although I have since decided I don't really like doing business with them....

i loved the FJ40 you built!!
is it still runnning?

and these new utes, should be AWESOME!!

any updates to the site yet?
last time i chekced it, there was just how youd bought them and planned to restore them both!

The updates to my site are just starting to appear. I have the section on frame modifications for the Truggy completed. More will follow. Sorry, but I am slow.

Just when I thought you couldn't possibly top your FJ40, Jack, you drop this drivetrain in front of us...sigh! Looks FANTASTIC, I can't wait to see how your project turns out! Love your shop, too, looks more like an operating room! :)

Joining this BBB has been like a glass of hemlock, just when you think you're perfectly content someone else shares a project that you *must* do to your Cruiser...sigh!

thats COOL! buildiung a truck and doing a site is TOO muhc for me

hell, just keeping one going and building another gets on top of me!!

Medusa,
Looks awesome & heavy.:D Gonna be killer for wheeling& strength though.
What is the url for your website? Would love to check out your progress. Brad.

whenever he responds, just below his response, next to his sig, or below it there is a WWW button

just click on that and go to his page!! ;)
