These are 6061 aluminum plate adapters for mating a 10-spline 4wd SM465 granny gear transmission to a 73-older 10-spline input Land Cruiser transfer case. They use 8 torx flathead screws to attach to the tranny, and studs to mount up your t-case. YES, STUDS! No more trying to fish a long fine-spline bolt down a 5" hole and hope you don't crossthread!!

There are three 5-1/2" long studs and two 2" long studs, all 1/2-13 sized. You WILL need to drill out the 5 holes on the t-case for these to fit...I drilled mine at 1/2" and it's tight...I'm gonna experiment a bit, but personally, 33/64th's is my recommendation.

WHAT you say, DRILL your t-case?? Interestingly, of the 5 holes I drilled out, only 2 of them actually removed any alum from the t-case, and that was SO minimal...the stock holes aren't a perfect size anyways, so taking a tiny amount of additional material is no major deal.

NO LONGER AVAIL!!!!

This is designed to work with the Advance Adapters t-case crossmember, tho personally, I'd create your own custom one....also, it DOES required you either A> drill/tap the tranmission output shaft for a bolt, or B> have a stud tig-welded onto that shaft. Additionally, a t-case saver like the old Amway unit is HIGHLY recommended, as is a WELL built skid plate.

http://www.ih8mud.com/tech/woody/sm465.html is the writeup for my install when I still ran the Classic Cruisers plate....directions are the same. Also, see treerootCO's writeup, linked off the home page at http://www.ih8mud.com

Again, kits include the 6061 plate, 8 torx bolts, and 5 studs. Shipping to the lower 48 included in the price as well!

Oooo pretty ;)
 
sweet...i may be in the market if this last fix on my crappy adapter doesn't work. just need to sell some parts off the 76
 
I've got a friend locally who works for a machine shop...

I just purchased 4.5 acres of land and am putting up a building prior to the house...and he wants a corner....hhhhhmmmmmm....this could be a NICE deal!! lol

(Guy build 4-cyl motors, 1" bore each, 30,000rpm.....amazing....)

You lucky dog, I would love a couple acres and of course a larger shop.
 
Woodie, post up rear and front pic when you assemble one, I am interested in the clocking on the t case with these
 
clocking is unfortunately impossible...believe me, we both looked at it. If you look at the bottom plate in the above photo, you'll see the recess where the back bearings of the tranny recess into the plate, two steps. The hole there is threaded for the bottom-most short stud for the t-case, and it's already stepped into a ~5/16" recess and not thru the full 3/4" plate. Clocking the t-case up AT ALL puts this threaded portion into the next deeper recess, leaving only 5/16" or so of material to thread the stud into....IMO, way to little.

Unless you've got another idea....
 
Opinion on plate adapter

They definitely look very nice, Woody!!!

Ever think about having the bottom squared off, leaving large enough corners to tap the plate on its vertical axis, so you could use it as your rear crossmember.
(Like guys running a 203 doubler can use the adapter (between the tranny and the 203 reduction box) as their crossmember).

This would also make it possible to incorporate your crossmember into your skidplate, or vice-versa depending on perspective.
 
I have a 2wd sm465. Will this adapter work if I find a different output shaft?
 
you need the 4wd 10-spline output shaft....its common to exchange the stocker with one that's already been tapped for the retaining bolt.

I "think" that once the shaft changes, all SM465's are the same, but ya might confirm that elsewhere....

-----------------------------
BTW: I just removed my tcase last night (Wed), I've been running the non-shaped prototype of the plate since early 2004. Zero issues, bolts still tight, I used standard grade 8 nuts and grade 8 splitlocks on the 5 studs, etc....I had a small leak since I opted to use the stock gasket between the plate and the adapter, and it was used and had a small tear....

Apparrently, it's plenty strong tho...I've not only busted 2 rear pinions this year (and with my rear 4-link, there is no axle wrap to cause it) but I also busted the front nosecone output SHAFT...not the alum cone itself, but the shaft...looks JUST like a busted pinion...nose cone is unharmed...

For those doing the Orion behind the plate and springing for the 6061 machined alum t-case nose cone, I'd spend the extra $$ to have your shafts cryo'd for the strength gains.....
 
Damnit woody i wish you'd come out with this earlier. :D

I had a nice SM465 but sold it because all the 465 adaptors were $500 plus, and SG's 420 adapter was $90.
 
SG had a damn nice adapter...with some luck, it will be available again early in 2005...with some minor adjustments...
 
<checks calendar....>

no word yet ;) will keep ya posted tho...
