I personally like the 3053a. I bought one for my '96 Ram to replace the sick auto, and went with the Spicer over the NV4500 because of price and strength. I have heard that the Spicer isn't great shifting, but I got a chance to drive a Deuce 500 miles and other than the odd shift pattern (which doesn't take long to get used to), it shifted quite well. I wouldn't hesitate to run one in anything they fit in.

Spicer 3053a to a Chevy Bellhousing

http://www.jpmagazine.com/techarticles/drivetrain/154_0509_spicer_3053a_transmission/index.html
The 3053A Spicer 5 speed comes with a SAE bell housing and therefore would'nt the 4bt just bolt up? No junky adapters necessary? If so would be a great alternative to the expensive NV4500. I plan on putting this in my newly purchased M715, what you guys think?
Here is a link about how to hook up the spicer 3053a to a GM/Chevy truck bellhousing. Since some of the 4BTs came with a GM/Chevy 4 speed this might help you. Also Cummins does list a SAE 3 Flywheel housing in their parts catalog.

only if .... and ONLY if your 4BT already has the SAE #3 flywheel housing.
If the engine doesn't come with it, you have to buy one.

I thought the Spicer 3053a from a military application comes with a #2 to #3 SAE adapter ring? The clutch housing on the transmission is a #3, but the flywheel housing on the multifuel engine is a #2, so they use a simple ring adapter.

Therefore, if your engine has either a #3 or a #2 flywheel housing the 3053a will bolt on (without and with the adapter, respectively).

please correct me if I am wrong.

"i dont care for the fact it has been completely discontinued and you have to 100% rely on aftermarket parts.

id rather run a weaker tranny that at least i can get another one easily....

thats kind of funny, the 3053 series is rated to 23k pounds, quite a bit more than just about any truck here weighs, also remember that the first deuces were introduced in the 40's, and quite a few are still running around still in service (i pass one everytime i go on base that still carries troops and supplies around base) and if you for some unknown reason break one, buy 4 more for the price of one nv4500. nuf said when i get back to the states this bub is running a 3053a.

3053a or 3052

My 4bt came with a sae#3 flywheel housing.
The 3052 bolts right up,so would the 3053a.
I used a 13" clutch,no problem.
I mated a dana 300 t-case to it,with only two custom parts.
The adapter plate (3/4" thick).
The bull gear bored out and resplined .
The 4bt-3052-d300 came out 3/4" shorter than the amc 304-t19-d20 that i
took out.

I would be very interested in pics of the adapter, I have a sae3 adapter on my 4BT and a sae3 3053 spicer but not sure whether to use it or not. I am in England and can find virtually nothing about it so don't know what flywheel and clutch to buy over here but seeing a tcase adapter might give me the needed push to dig a little deeper .

flywheel

The flywheel that i used is cummins#3908569.
I will take a picture of the t-case adaptor and try to get it posted.
I don't have pictures before the installation though.
I do have the drawing that I made with all the measurements,and the machinist phone number that made it for me.
I bought the clutch from south bend clutch in indiana.
My flywheel housing is cummins#3903282 .

So on a slightly different tack: does all this mean that you could use a 3053 on a B3.3 since they already have SAE housings, and not have to use a Phoenix adapter??

Tanks for the info, did yours look like this from the front? Which particular clutch from south bend did you use? did you have to redrill the flywheel?

But....do they have the right size SAE housing?
And what about finding a clutch disk for that small of a flywheel that fits over a 1-1/2 x 10 input shaft? I really doubt it. Also, there is some pretty good drag from a trans that big.....whatever mileage gains you get from swapping to a B3.3 may be lost due to efficiency losses through the transmission.
