WANT TO BUY Dana Spicer 5831 Aux Transmission

[Don Wilson jr]

Needing a Spicer 5831 auxiliary transmission with the .73 Overdrive, to bolt behind my Allison Ht 740 Transmission. This is a 3 speed gear box with a direct, low and overdrive also known as a Brownie box. I know that these are really getting hard to find. This needed for my Mack R model that I am restoring into a giant Pickup truck. Please let me know if you have one or know where I might find one. Contact Don (859)525-6798 or email donwilson5201@gmail.com

How are you planning on mounting it?

The box is almost 2 feet long then you add the length of the drive shaft and work to get it mounted and the shifter working it becomes a project.

I was going to do the same thing but decided to convert my MT643 to a MT653, this added an additional granny gear, and change the rear axle gear ratio to effectively give me a .80 overdrive.

Actually the new gears came with a rear frame clip I bought for the air ride suspension.

I have considered the length of the gear box and the drive line modifications. This is pretty standard stuff for me. I am the Plant Supervisor for a Fire Truck manufacture, and Dirive line modifications are performed daily in our shop. Of coarse this project is me at home but can fabricate anything that I need at work. My biggest problem at this point is locating a Gear box. No having much luck at this point!. Any help locating one would be great.

Thanks Don

I know where there are three 8341's and a 7041.

I think the Plant Supervisor should talk to the Purchasing Manager and go to work with a really big lunchbox one day.....

How about a couple pics of your R project?

I read what I wrote in my post. It sounds a little arrogant. I really did not mean it to come out that way. I think one thing and write another. I am definitely not that way. In the future I will proof read a little closer!. About your question about pictures, I do have pictures showing what I started with, and where I am now. I have not figured out yet how to post them! As soon as I get it worked out, I will post some of them.

Thanks Don

No worries. I was thinking of the old Johnny Cash "One Piece at a Time" tune where he built a Cadillac by taking parts home.

Based in the information I gave been able to find the Spicer Auxiliary Transmission Model Number means

First two digits max torque times 10

Third digit is the number of gears

Last digit is the case

1 cast

0 aluminum

I hope this helps.
