SM465 Rebuild ?

Hello !
I spend most of my time in the Jeep board, but I have a GM based question and I thought this was the place to go.

I am in the process of building a Jeep with a GM drivetrain.
The first think I want to do is to rebuild my SM465. I want to gather the correct tools for the job.
I know that I need a long puller and a bearing splitter to take the transmission apart.

My question is
What is the best size splitter to get, and what is the best size puller to get. Is a 2 jaw better or will a 3 jaw work?

And it anyone would have a link to a place where I could get said tools on the net that would be great.
Thanks very much for any help.

Re: SM465 Rebuild ?

Piggyback on Olin18's questions:

I have a 1977 NP205 transfer case mated to what I think is an SM465 4-speed. If any of you have any tips for upgrades to this tranny, please let us know. I have heard rumors of upgraded synchros and such, but dont have any specifics. I will be rebuilding both soon, and can use any tips anyone has.

Thanks,
Paul

Re: SM465 Rebuild ?

The SM465/NP205 is probably one of the best trans/xcase combo ever offered. I have no question that the SM465 will hold up to anything I throw at it. There is no need at all to upgrade. Just replace any worn parts. The only reason I am even rebuilding mine is because it has a TON of miles on it.
I am just having trouble finding the information on the size of splitter I need, and the reach of the puller.
Thanks again.

Re: SM465 Rebuild ?

I rebuilt a SM465 and NP205 combo last summer. For the SM465 all that I used was a modified 2 jaw puller and press. The puller was modified to pull the shaft bearings out of the case. Once the bearings are off, you can remove the gear sets from the transmission case. After the gear sets are out of the case you can use a press to disassemble and reassemble the gears. Other than that I just used hammer and brass drift. If you have any other questions about the rebuild just ask.

The 2 jaw puller with modified ends:


I got my rebuild kit from Novak Conversions . Here is a kit that is suppose to help fix 3rd gear hop out.
