Allison Behind the Multifuel

[bottleworks]

An Allison MT-647 freshly rebuild soon to behind the multi-fuel. Stay tuned.

Does that transmission have the overdrive in it?

I just did 240 miles straight through in my 915a1 with an allison. It was a real treat. I hope yours makes driving as much of a pleasure as the a1 does.

This should be interesting!

The MT series transmissions do not have an overdrive.

 

[ODdave]

lil overkill for a multi isnt it? how much did you get the trans for?

 

[shannondeese]

I was going to put an Allison RDS 2500 behind the multi but backed out due using the trans in another project. I still think about it and maybe one of these days I'll make it back to the project.

Keep us posted. Thanks

Hey Shannon, whats the latest on your Cummins swap? Werent you working on an Allison/Cummins combo with Howard's parts?

If it is true that the trans doesn't have an overdrive, it's going to slow your top speed down quite a bit.

I accually like shifting gears and wouldn't install a auto if somebody gave me one. To each his own I guess.

Yes, the MT 647 is direct drive in 4th gear. The MT 647 has the same specs as the 643. The 647 is just a bit beefer for transit use. I will be mounting larger tires once the trans is installed. This should equal out the gearing difference. I only drive the truck locally anyways.

I paid $280 for a surplus lot that included the transmission and about $280 worth of steel and aluminum. In the end, I should have zero in the trans. At first, I was going to use a B400 (w/ retarter) trans, but this deal was too good to pass up.

The trans is the easiest part to acquire. It's all the other bits and parts that will be the PITA.

bottleworks, that is a great deal, what other parts you will need to make it work with a Deuce ?

Is the transfer going to have to be moved back ?

Please keep posting as it develops.

Thanks,

[mudguppy]

yeah, you're going to have to move the transfer rearward.

take lots of pics.

It's closer to what isn't needed. It will need SAE #1 to #2 bell housing adapter, crankshaft spacer, flex plates, starter ring gear, oil to coolant cooler, piping for associated cooler, drive shafts, Allison shifter, TV valve linkage, 5 ton MF bell housing w/ true #1 SAE pattern, and a lot more.

To power the winch, it will be converted to full hydro. This trans has a PTO provision. There will be a hydro pump running off that PTO. That alone adds a lot of additional parts and cost.

This project will progress as fast as money and time allows.

let me know if you need help spec'ing the pump and motor.

How did this ever turn out?

The truck is very low on my "To Do List". I haven't touched it. In time, I'll get around to it. I have been gathering parts here and there. Once I've got all the main bits rounded up, then something might happen.

Guess you found out already that the 5ton bellhousing bolt pattern is SAE#2. See http://www.steelsoldiers.com/deuce/14719-ldt-bellhousing-sae-size.html#post144267
Not clear though, how you would run that behind the MF in a Deuce?
