Are you interested in selling it? I might have another lead on one as well, just checking with the guy.I think i have a SAE 2 to SAE 3 ring adapter sitting in my garage.
Sergio.
Sorry for the late response, but looks like I have found one.Yes, i don't think i have any use for it.
Just the housing Adapter so I can bolt up the #3 compressor housing to my #2 Detroit housing. Here's adapter ring on my #3 Allison 1000 housing.2-3 adapter changes the "A" dimension on flywheel . Or was it originally engineered that way ?
Lol, true never have to worry about that coming off.Man, I believe that adapter plate needs some more bolt holes. LOL. They must have been afraid it was going to fall off.
That's a nice adapter.When I found out what they wanted for one, I made one by hand. I started with a 3/16 thick stainless steel disc 20" diameter. (material I had left from another project) I laid out the 24 3/8 bolt holes and drilled them. Next I roughed out the center hole by drilling many 1/4" holes next to each other in a circle and cutting between them with a saber saw. I mounted the disc (now a ring) on the #2 housing on the engine and doweled it in place. (now the fun part) I mounted a lathe tool bit to the flex plate along with a long handle to turn the crankshaft. After several hours of turning the crankshaft and slowly inching the tool bit out into the ring (with lots of measuring I got the center hole in the ring to the correct size. Once this was all done I pressed thread inserts (PEMS) into the inner set of bolt holes. I had to make a centering piece to locate the torque converter and once again lots of careful measuring, turning and bolt hole drilling. I haven't had a chance to run the assembly yet, but everything should be concentric within a few thousandths.
Lathe tool bit is to the left of the larger "C" clamp

Before the thread insert were pressed in. Note the 3 small dowel pin holes.

Does the Allison 1000 have a rear mount? If it does there's nothing wrong with adding a crossmember for support. I know when I bought my engine it just had the 2 rear housing mount with the Allison 545.There was a guy on Ebay trying to sell cracked ones from multi-fuel military trucks for $250 and I knew I could do it myself for little more than my time and I wanted the thin style, so I went for it.
Do you have an opinion about mounting an Allison 1000 off the back without a rear mount. I'm set up with one front mount and the two on the flywheel housing? That is all the Allison 643 had.
There's plenty of flex on the rear trans mount, so I would not worry about frame flex.It does have a rear mount, but I worry about adding bending stresses due to frame flex.
I've heard of suspending the rear of a trans with springs on a class 8 truck. (just to take some of the weight, but nothing rigid)
