Quick question,

I have been contemplating doing the married 205 to a divorced 205 doubler. I currently have an SM465 trans with a married 205, this case will get the front output hacked off for the Hi/Lo range portion.

I will route this to a divorced Dodge 205.

Now, I have seen it done two ways, one with a small driveshaft, between the two cases, and one with a partial CV knuckle and u-joints.

I know the CV knuckle and U joints will give me the shortest combination possible.

The question I have is, If I removed the rear out put yoke from the married case, this should be 32 spline, and then removed the input yoke from the divorced case which should also be 32 spline, then had a 32 spline female coupler machined to the same dimensions as the OD on the yokes couldn't I mount the cases closer together?

This will eliminate any u-joint failure between the two cases, and still allow me to mount the second case damn near flat.

Is there any downfalls to this set up?

I know if the output and input shafts are not perfectly true to one another it is going to accelerate bearing and seal wear, but other than that any other issues?

you could use a GM 32 spline input *(short or long) and build an adapter to bolt the two cases together....

Search for 205/205 doubler or something to that effect. There are pics on this site that show a custom built adapter to mount a 205 to a 205.

Thats is the intention but I figured instead of hacking something together I could just get a slick OD with 32 spline innards. That way I could keep the mounting brackets simnple and still retain use of the seals on both cases.

I have checked for an adapter and it's not necessary as I am using a married 205 already bolted to my SM465, the second case will run a crossmemeber style braket.

I am mainly looking at the coupling between the two cases.

[foghornleghorn voice] I say... I say... pay attention son..... [/foghornleghorn voice]

I don't give a shit what trans you're trying to use.... I'm talking about marrying the two 205's together.

he wants to do it fugly

I dont see the issue...

remove the seal retainer from the front 205's rear output, cut off the threads from the shaft, install a Chevy 32 spline short input into a divorced case, build a tube type adapter with a lathe to accept the bearing snap ring to locate the adapter with bolt holes to bolt it together to the front and rear case... shouldnt take but about 6 hours to design and fabricate.

Pay attention I am pretty good at that as well as searching, but reading comprehension owns you :flipoff2:

I am not looking to join the two cases together, I am looking for an alternate method of coupling the out put of one shaft to the input of the other.

I am thinking something along this line,

Grump, is this what you are describing?

Do you see any issues with coupling the shafts this way, other than misalignment being a possible issue, accelerating seala nd or bearing wear?

That is the only issue I can think of off hand, was hoping maybe someone else had tried this or can think of any thing else that might be it's downfall.

issue is you have 2 shafts, that need to be aligned, floating around = boom
either do it nice with a proper adapter, or do it ghetto junk with a driveshaft between the case
you cant do it with dry coupling like in that diagram

Sweet that's what I needed to know.

GM offered a 32 spline input. its a female input. it will slide over the 32 spline output shaft on the other 205 case. No intermediate coupler needed.

dude, you keep up w/the tech and they're going to change your name to "grumpy 'n smart ol fart" or some such... :D

I think my signature line fixes all of that... nobody will mistake me for smart, just mean.

works for me.

Which is why I was telling thick-headed jr. to marry the two cases. If he doesn't positively afix both cases together, he's going to do nothing but destroy shit as one case torques or flex differently that the other. That's the only way to use the style of coupler he wanted to use (or the method Grumpy suggested) without fawking shit up.

I might have to do this type of doubler, just to see how it works.
