Does it have pins to keep it concentric? Good idea making a jig to keep it aligned when machining!
You ended up running that bearing?
Where there's a will there's a way!
Ill have to measure my stuff when I get back. will be interesting to see how they compare!
I'm not really sure. I probably wouldn't run it. It's just another bearing to spin that will never be loaded up.
Wyell just have to see how it all fits together.
Does the machinist have everything he needs to check the concentricity?
I'm would put a lot of emphasis on this. It will kind of...
That makes sense. That is because the transmission output shaft typically supports the input gear of the transfer case. When you have that adapter shaft you have to support it on both ends.
The RF1A has it's own bearings on both sides of the input so this bearing becomes unnecessary.
Maybe you should trim that shaft yourself?
Just use an angle grinder... You can use clay to make sure you get it nice and tight.
Have you looked for a seal that will fit where that bearing rode? Or are you really going to try to run that bearing in there?
Engine sounds good!
Yea I'm not sure about mixing the two. I know that my toy box likes a hair under one qt of fluid before it starts to weep out of the shifter. I have more case volume than a typical ToyBox because of the tail housing it mates to.
There are a bunch of potential issues with this. The level might...
So a few things I'm unsure of...
The RF1A case has a bearing on both sides of the gear set, and the output shaft of the 4500 does not require a support so I don't think you will be needing that bearing in the adapter between the two.
However there will need to be a seal between the two boxes...
This is an interesting prospect.
I don't know if you would need to heat treat the aluminum for this. I would farm that job out to someone who can weld this properly.
I would imagine that AA makes only a few patterns of 4500 tail housings. Maybe you can get one that is not machined on the...
You can always run that 4 speed for a few years.
I would still call AA and see why they pulled the rf1a adapter and try to grab one of they have it.
The most important part of the ToyBox is the output and the transfer case side adapter plate anyways.
You can probably sell that left over...
Just to clarify:
So if this above makes sense you can see that the input shaft is part of the input gear, but the output shaft is actually separate from the low range drive gear that rides on it.
The input is available in both 21 and 23spline in both 2.3 and 4.7 flavors new off the shelf...
