@Godfather90 , your idea worked beautifully. I tapped an upper alignment pin hole, stuffed in a spacer, and it popped right apart.

I'll draw up some plans on how I think I can get these two to mate.

Man look at all that surface area!

No wonder it was difficult to get it apart...


Glad it worked out!

Now you have th ability to seperate it again in the future as well which is nice.

Nice work Noodle. Hey what’s the tranny that came with your Toybox??

It's an SM465. Rarer old 4x4 10 spline version. Rebuilt by Georg @ Valley Hybrids and for sale. ;)
 
I believe the hold up is the input and the output shaft. Only going by assumption though so don't take my word.

It would be cool if they just made th output side so people could run different transmissions. There are a few RF1A adapters on the market to give a few combos that direction.

There are manufacturers who produce different outputs for the RF1A; maybe they would be interested in hobbing differently with enough interest. They could use existing blanks. It would be several tool paths simpler than the ones they manufacturer now as well.

That adapter plate looks like it's very easy to make. Surprised it's not made anymore.

That's why I was looking at making my own. Its the output shaft that would be a pain to get made custom.
 
Is there a 10 spline output available for the nv4500¿

Yep. I have one coming from AA that will replace the 16 spline one I currently have.
 
Sounds like it should be fairly straight forward then!

I'm excited to see this come together!

Mike

I am too! I just need to mind a machine shop that can help make this adapter plate.

It's not possible to re-work that transmission side of the plate you have?

What's the stickout look like with this 10 spline output?

What do the two tail housing patterns look like?

It might not be as hard as you think...

Let's get some pictures up!

I may be able to modify your adapter plate or help with making a new one. It's going to depend on how much the AA tailhousing sticks out of the NV4500 tailhousing.

I am working on that now. I'm not sure what the stick out on the new output shaft is, but I believe it is quite a bit. Can anyone with a 3-speed case confirm that it is just an input gear, not the whole female shaft like the 4 speed has?

Here are the differences in the patterns. Not really to scale, the toybox is about the same size as the tail housing.

I'm thinking that I am going to need to get a piece made for the upper portion of the tail housing to weld on and have the bolt holes drilled and tapped through to mate them. I could do a completely separate plate, but it would be more length to the drivetrain.

What method do you guys think you would do? What would be easier?

What's the other side of the ToyBox adapter look like? There's also that round pattern tail housing for the 4500 that might be easier to adapt.

Do you still have the original 4500 tail housing?

Just thinking out loud here.

I'd have to get a new tail housing for the NV. The one I have is the long version, so I'd really prefer not to use it.

Here is the other half on the SM side. It's exactly the same as the toybox side.

I want to see what the side mating to the transmission looks like.

Ideally you could rework this part to mate to the 4500 and get the stick out right.

That way the other side of this adapter remains unaltered.

I can go pop it off real quick. I have no idea.
 
Yeah, you have a aftermarket tailhousing on the NV4500. a stock one from a Dodge will be a simple 6 bolt round pattern and much easier to adapt to. Additionally, The GM tailhousings are about 2" longer the Dodge version tailhousings so MAYBE if you use a DODGE tailhousing with a output shaft intended for a GM tailhousing it will stick way out past and give you the room for your adapter.

I think making a new adapter that bolts to both the Marlin SM465 adapter and to the NV4500 tailhousing and leaving both unaltered would be the way to go if you can. The Marlin adapter to the crawlbox seals it and holds bearings, right? I would not want to get into re-engineering that if you don't have to
