M108 deuce wrecker gas to multifuel swap

Decided to start a new thread for this instead of continuing the hi jack of Kenny's thread were he did the same. Finally started the swap today. Please chime in with any pointers.

the engine is ready to remove but the sun went down to fast .

Here is a picture of the m108 and the Donar truck.

I see lots of fun coming your way Chuck. I can't wait to see it.

What was the matter with the 331?

 

[cattlerepairman]

Unless you are super pressed for time, I suggest to unbolt and remove the winch as well. You already need to disconnect the winch shaft. The winch sticks up really high and you can easily catch (and break) the engine mounts or smack the oil pan on the darn thing.

M108 is awesome! Any chance the rest of the donor truck is going up for sale? I have an engine and trans that would go right in! I pulled cab to crew cab the triaxle

It runs, smokes a lot,burns fuel like it's going out of style, other than that its fine. the cab needs replacement as well so all things a2 are going into this truck including the air shift axle.

I will be using quite a bit of the Donar. Planning on moving the air shift and I need some of the dog bones as well. I may purchase those however. Another member wants the bed.

I may just do that. The front bumper is coming off as well. The original is tweaked.

Please chime in with any pointers.

A.
Now is the time to rebuild the steering box. They always need rebuilding and it's easy breezy with the engine out.

B.
Now is the time, with the engine out, to do all the miserable stuff like going through the injection pump to replace the hydraulic head o-rings and reseal the booster pump.

C.
If your donor truck has the M44A2 style front engine cross member, it might not be a terrible idea to check it for flatness and if it's good, do the MWO brace. More info here: http://www.steelsoldiers.com/showth...tween-M35A2s&p=1589557&viewfull=1#post1589557

I suppose you have a perfectly good reason not to just put the wrecker bed on the other truck then?

Reenforced frame and lockout bars on the rear springs was my main reason....and the logistics of moving an 8000# body.

As Kenny mentioned, the double frame is the main reason. these are not just a cargo truck with a body on it .

 

[Jeepsinker]

I figured something like that. Had to ask though.

 

[Stretch44875]

Don't know if you saw my M108 swap. I don't remember anything special. Swapped the front crossmember from other truck, and one of the rear mounts. Had to remove a rivet from the spring mount to bolt crossmember in. This is all memory, so I could be wrong. It's the same has repowering a regular M35.

Made a little more progress today. Got the old motor out.

Rocky,my dad, and father in law, all chipped in.

 

[hndrsonj]

Was it still 24V? Want to get rid of the engine/radiator?

 

[Jeepsinker]

You are really after that man's old motor aren't you?

 

[SETOYOTA]

A few more. Yes it's still 24 volt. I have another guy who said he wanted the motor a few months back when he heard about my swap, If that falls through it will be available .

Short high jack then back to the regularly scheduled program. I remember the surprise I got pulling the engine out of my M108. I strung a chain between trees and dropped a chain call. Anyways, I pulled it with the trans attached. As I rolled the truck back Inwas greeted by a winch PTO that had an accessory drive. I seem to end up with lots of rare PTOs.
