I am scrapping out a 1974 Fleetstar that has a CAT 3208 which threw a rod thruogh the side of the block many years ago. I bought the tandem axle dump truck for the dump body and hoist. I want to save the transmission for the future in case the manual transmission in my Ford L8000 ever gives out, it also has a CAT 3208. Can anyone help me identify what this Allison transmission is exactly?
Probably a 653, might be a smaller one.
It matches with pictures of MT653s, all the bumps on the case in the same places and the bolt on back section.
So I was able to download a MT643, MT653DR brocure. It definitely does look like a 653DR 5 speed. When I clean it up I'll see if I can find a tag of somekind.
Ya MT653, mechanical shift pto. It would have been nice if it was a ‘hot shift pto’
It may even be an older MT650 if its original
Definitely a 5 speed and not a 4
The long bolted in section tells you it is a 5 speed. There were older ones that had 2 digit numbers instead of 3 but I can't remember the nomenclature any more. I am kind of surprised it is not one of those.
The only old one I can remember is the ht 70, which is a bigger trans that that, just a bit smaller than a 750
Birken, your right in 1970 they used the MT 41.
My rig came with an off road trans, the manual valve body version of the ht 70, clbt 4460 in 1965
