  1. Thanks for the information. I measured from the back of my Allison to the rear end. This is going to require two Very short! drive line connections. Will need to talk to my drive shaft guy to see if it is even possible. From the Transmission mounting flange to the center line of the rear end is only 57". Subtracting 33" for the length of the Auxiliary, this only leaves 24" for two drive lines. This is going to be a tough one. Does anyone have any thoughs on this.
  2. Wanting to install a Spicer 8341 in a 1976 R model Mack. Does anyone know, how long from center of yoke to center of yoke a Spicer 8341 is. Need overall length to determine if I have enough room for one. Thanks Don
  3. I had ask for help in a earlier post, locating a Spicer 5831A gear box. I have had a lot of response helping me locate one and others have given suggestion on the installation. I would like to Thank everyone for that. But It has been pointed out to me by several, that the 5831 may be a little small going behind a old 300 Mack engine, and that a 8000 series Spicer would be closer in line with the torque. NOW! the question is does anyone know where I might find something like a 8341 which is a 4 speed. I am not sure which model number was used for the 3 speed and would be interested in either one. I would like to still have the .73 Overdrive but again have been told that they are very rare. .84 will work. Any help would be appreciated. Thanks Don
  4. 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
  5. 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
  6. 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
  7. I have a 1976 R Model that has sensors on the front and rear brakes. Question, are these ware sensors or ?. Thanks Don
  8. I have a R model that was originally a Fire truck that was built in the Mack factory. What does anyone know about front disc brakes that are hydraulic powered by air. It is a factory installed option that is a Kelsey hayes system. Are parts still available for this type of brake system.
