SM465 -> D300

Ok, either I'm going nuts, or this is *VERY* possible on a low budget.

I just got back to school today, and I had an email from a friend who has my.. (well 1/2 of it is mine so far) SM465.

It's the 4wd, 32 spline output version.
He had finally measured the output shaft for me.

1.5" diamiter after the shaft necks down.

Great I think.. and over to the D300 thats currently in peices in my living room.

I don't have a micrometer.. so I folded a peice of paper to 1.5" across.
Go to slide it in the input.. and there's no way it's going in there.
Hrmm.
SO I fold it to a 1.25" wide peice.
Slide it in.
It fits.. but only in the grooves.. so.. that means the outside diamiter of the splines in a D300 are 1.25"...

I'm going to go re-measure the SM465 again.. but even if it's 1.25" OD.. then I should be able to get it resplined by someone like OTT, and have it fit perfectly into the D300.. right???

Or was there another reason people suggested this was a bad idea?

Re: SM465 -> D300

Somewhere, someone has done a SM465 to D300. I was bored so I did a google search. Here's some of the things that I found. Looks like the Toy Ota guys have been all over it.

jeeptech.com

4wheeloffroad.com

jeepaholics.com

ih8mud.com

Looks like there are adapters and the SM465 has different versions with more than one size output shaft.

Good Luck

Re: SM465 -> D300

They all reference to an adapter though

I'm thinking.. that because the 208 has a similar bolt pattern as the 300 (5 of 6 bolts match up) a little drilling of the adapter that came with the tranny..

and then respline the shaft (was 1.5" respline to 23 spline 1.25" ) and it should mate up.. cheap and effective..

no?

Re: SM465 -> D300

If it has a 32 spline output, it's a post 80 version and they are way too long for adapting to a D300. Novak doesn't even make an adapter for this tranny without swapping out the rear mainshaft because of length issues. The pic shows an early 4WD 10 spline, above a 2WD 35 spline, above a late 4WD 32 spline for illustration.


Not trying to rain on your parade, just trying to help.

PS, have to credit the pic to Novak's sight. If you do or don't use their stuff, they have great info on the sight.

Novak Adapters has some very good info on the SM465 and D300. Here's the link

http://www.novak-adapt.com/knowledge...ge_gateway.htm

It's just more info you can use. Hopefully it can be of some use for you. They do mention the 1.25" shaft on the D300. I didn't read the SM465 info.

Good luck

Re: SM465 -> D300

Well i've done some measuring...
The 350>SM465>12" 208adapter>D300 is SHORTER then my 4.2L, AX15, NP231.

There's also the possibility of getting the 208 adapter shortened.. it wouldn't be THAT hard.. just take a jig, plasma cutter, and welder.

I'm looking at them right now. and The SM465 necks down to 1.5", the D300 is 1.25" 23 spline input.

So theoretically, I should be able to get the output of the SM465 resplined (under $100 around here) to 1.25" 23 spline.

I could also get it splined the entire length for now.. so I can use the 208 adapter.. and then eventually when I get the other adapter fabbed up (cut down) I could just take a zipdisk to the mainshaft and shorten it to the required length.

Also, the NP231 bolts to whatever a D300 bolts to.. so theoretically I could keep the NP231 until I want to swap the front axle.

I'm going ot get out the tape measure some more.. but I also.. (if I remember from the rough measurements I first took) think that I can slide the 350 forward enough so that I can mount the 350>465>208adapter to the NP231 without actually moving the np231 at all.. which would alow meto use the same driveshafts until I get my new ones made for the D300.

Lemmie get the trans/case/adpater.. and jeep together... with a tape measure.. and I'll try to get pictures ( if the camera works)

Re: SM465 -> D300

Just some thoughts on your project. Keep in mind that most output shafts are heat rolled splines, which are different and much stronger than cut splines like axle shafts etc... have. Most machine shops don't have the ability to put in anything but cut splines in a shaft, and I worry slightly about the durability of a cut spline output shaft. My other thought is, moving the engine forward may make the project easier, but keep in mind engines are usually positioned for best weight transfer, and load bearing. Just because moving it forward is the easiest method, doesn't make it the best. Don't get me wrong, I think your project is cool, and I applaud your ingenuity. Just trying to throw out some thoughts on the subject. [img]images/graemlins/40BEER.gif[/img]

Re: SM465 -> D300

Hrm.
Forgot about weight.

I'll see where it ends up, but I doubt I'd go moving it 6+ inches.

The D300 is heavier then the NP231.. and the SM465 is heavier then the AX15..

OTT Industries has the capability to re-spline axle shafts and tranny/case shafts.. properly..

Re: SM465 -> D300

Cool, sounds like you have it worked out pretty well. I dropped the big $$$ for the Novak adapter last year and am happy with it, but always looking for cheaper, practical solutions. Besides, I have a spare 2WD 465 in my shed, and who knows where it will end up. [img]images/graemlins/grin.gif[/img]

Re: SM465 -> D300

Thats what I think I'm going to like about my new driveterrain [img]images/graemlins/laugh.gif[/img]

SBC>SM465>D300

$500>$50>$100

Craps so cheap and common.. i pitty the fool in my club who thinks adapting a Toy 22R, to an SM465 to a D300 is a good idea.

I mean heck.. if I were to drive to the states.. run Tellico.. granade my tranny... I'd just have to drive to a junkyard.. .and grab one of their 400 trannys lying around.
