m54 repower

[atilathehun]

I am thinking of repowering my m54 it has the multi fuel with the direct drive in it now the motor is tired and the trans is not far behind it. I would really like to put an auto in this truck but i would like the new trans to bolt to the old input flange on the transfer case can this be done? What motor and trans are a good match for a heavy truck like this all thoughts are welcome or should i just save for a newer m35a3.

If you do, I would maybe want your old tired LDS to rebuild for my 109...

Not sure on a tranny, I'm not very well versed in autos. I'd go with a cummins ISX

i will keep u in mind ferroequiologist

Cummins 6bt or International 466( the mechanical version) then mate it to an Allison tranny.

6.2 V8 Diesel would be a good choice too.. well just need 3 or 4 of them. Really I would go for a NHC-250.. you can get the engines for 1000 bucks or so and its military so you all good.

Direct drive huh.......................so you have the "wrong" transmission in yours too??????? Guess we need to listen to the experts and install the right one


Save your $$$ for a 800 series and sell the M54 as a whole to someone who would appreciate it for what she is

Reminds me West. i need a OD trans to go with that LDS when i come out..

CRAP you keep making me pick up more and more lol

I am going to save some $$$$ for a m35 with a shelter on it that way i dont need a cdl and i can run regular plates on her now the ? a2 or a3. An a3 would be nice by the time i have the money for an a3 the a2's will be gone What things should i do to park the m54 for an extended time pull the battery's of course and put stable in the fuel and oil or is there more

She would make a good static display for a legion or vets home when i get another truck she my get donated for that task if know one wants her. But i aint ready to sell her yet

Hijack.................

You know I wish someone.....I know DD is really busy.........would give a good telling of why some have the Direct....and then some have the OD. My 5 ton trucks are of both flavors. Why?????????????????

Let me do some digging. I do know the OD trans was for the ENDT-673 becuse of its power band, it was better suited for this gearing as the Multi was suited for that gearing(direct drive). Remember, these trucks were not designed for constant highway use like we all use them. I am sure that the motor pool experts found that the OD trans would go nice in the multi and I am sure that some were done on that level. Both my M52 and M54 are direct drive transmissions.

Wesfolk, consider your self lucky for that you dont need to be on the search for a OD trans like I am for my M54. The reason I posted that was because some one on another thread about atilida's truck said that I had the wrong transmission in my M52 and that I should be able to do 60 mph.

oh yesterday i went out and started her it was colder yesterday she started right up and ran fine for 2 hours up and down the road when i got done i opened the hood and watched things looked in the radiator with it running no bubbles or oil but around the head gaskets there was oil blowby coming out between the head and block so i think i am looking at a head gasket change do the studs stretch over time on this engine. As for doing 60 in a truck this heavy they have bigger stones than me if someone pulls out in front of a 5 ton or duce with that much steam behind it they are done for. I can deal with the tranns for now i just want the truck mechanicaly sound i have had it a month and pulled it home 2 times now.
