REO to LDS Transplant

[Tavish]

Wondering if anyone has removed their REO engine and put in a LDS? Looking for any pointers or issues that may have come up. I have a 1952 Studebaker M35 and that 331 is just not a happy engine. As much as I want to keep it in there, I'm thinking that it's time to repower. Is my thinking correct that the LDS should pretty much be a bolt in process without tons of modifications like with a CAT or Cummins repower?

The multi-fuel uses an SAE bell housing so if you're REO engine uses an SAE the same diameter then that's a go .

So then it's just a matter of the input shaft in the transmission, is it the same transmission ?

I don't know, but if it is then that's a go, if not you might be able to use the clutch setup off of the REO and make it work, so if all that bolts together then your front motor mounts that's no big deal, if they don't just bolt right up you can pretty easily make something to come off the frame or crossmember and hold the front of that engine up .

Then add diesel .

If you don't like that engine and you have access to a multi-fuel, then pull that thing out and get after it, it'll go in there one way or the other

Cant give you an absolute answer to you question (obviously) but since no one had responded yet I thought I'd give you something to think about .

Yes, correct...! It has been done countless times, and not only by the military.

Extensive M108 repairs, part 2

Here's the thread on the first time around. http://www.steelsoldiers.com/deuce/33686-extensive-m108-repairs.html?highlight=m108+repairs So, after finding out the gasser engine had a bad rear seal, and a bad head gasket, I moved up the timeline on installing a Multifuel. So truck is getting...

Now, if you were planning to use one of the 5-ton 465LDS engines, your first step would be some modifications to the engine itself - before it can go into a Deuce engine compartment.

will a 5 ton lds intall to a deuce

i understand the engine will go right in.The question i have will the clutch and pressure plate from the 5 ton mate right up to the deuce transmission? anything else i should know if i do this swap. how does the lds preform in a deuce?

Different transmission guts, the gasser is direct 5th, the multi is 16% OD.

Same case, either will fit.

 

[gringeltaube]

...... the multi is 16% OD.

It's more than that....

1/0.79 = 1.266 That would be almost 27%

 

[G744]

Nope, the 3053 has a .85:1 OD.

So I was off a %.

 

[gringeltaube]

Nope, the 3053 has a .85:1 OD.

Sorry but who ever told you that has never been inside a 3053 and actually counted teeth...
Also the TMs do have mistakes, but regarding the speed ratios of both, 3052 and 3053 transmissions, the info is accurate and correct.

 

[G744]

Agree-disagree.

I've measured RPM in & out.

I can't tell what transmission you have...
AFAIK .85 OD did exist - in the civilian world and way back in time when dinosaurs were alive...)
But fact is that the military has never put anything other than the 0.79 version behind the Multifuel.

Maybe you're thinking about a 5-ton...

No, this is about the M35 and we are talking about the Spicer transmissions for the Deuce, here.

If the OP ends up swapping his "Gold Comet" with a Multi he will have to replace his 3052 (5th direct) with something else, with at least 25% OD.
Easiest would be the Spicer 3053 (or 3053A) and they all have the very same gears (as shown in post #7).


So, let's get back to the original topic, please...

And the rear mounts are in a different spot.
