My '68 M715 Build Progress Page

I always knew there was a setup to do that but I had never seen one before...thanks for posting!

Seeing as it appears to be a hodpodge of both 24v and 12v items, I highly doubt it was built that way. More than likely it was a swap somewhere in it's life after it left the military. All the trucks in the military have used a standardized 24 volt system since 1952, these are known as M-series vehicles and where an upgrade of the electrical systems compared to the old 6 volt systems in WWII vehicles. By standardizing the electrical systems in all M-series trucks it makes supply and service easier for the military.

AMC was not involved in the 230 at all. Kaiser Jeep owned Jeep until 1970 or so...AFTER the 230 came and went.
Kaiser did use the civilian version of the 230 from 1963 to 1965 in the Universal series and the Full Size Jeeps. Then they redesigned it and used it from in the M715 family, correctly called the G890 series, from 1966 (prototypes) to 1969 (Possibly early 1970).

There were no other engines or transmissions used in the stock M715 trucks other than the modified for the military truck 230's.

There has been talk over the decades here at the Zone about the different input shafts needed to swap other engines in and mate to the stock trans and the T18 vs T98 diffewrences as well. We have been told uin years past the the 304 and 360 AMC have been mated to the T98 by swapping input shafts, bellhousings and adding a spacer...so I knew it has been done...just had never seen one.

I am extremely confident that someone did this with your truck...found the components and swapped the stock setup to a less troublesome, more common engine.

Its not a bad thing...would have been interesting if such a thing had been done factory...maybe they would have lived longer...

To me, the 230 is just another of the "Wow...what is that?" things about the M715 that make it desirable to some people....like me for example...but nothing wrong with yours...I love seeing all the variety and possibilities...THAT is a big reason we ever got started right there!!

I agree with the above. I also have no problem with the original 230. It did what it was designed to do. Unfortunately, today so many out there (not me) want power steering, hydra-boost power brakes, lots of torque and so forth. Nothing is wrong with that. It is just not what I remember and I like the truck stock. I love the whine of the transfer case. That is what I remember from my days in 1969 and 1970.

Its all personality!!

One more thing...the transfer case was stuck in 4WD after a short test run: front axel was engaged and transfer case in low gear. Wouldn't disengage.

I discovered that in order to disengage the transfer case and front axel, I need to drive in reverse for a short distance. I guess that "unbinds" the gears [takes the load off... so to speak].

Who knew. I call these idiosyncrasies, "special features".

Things that make me go "hmmm".

I found out the same thing when I was in the army. It can be cantankerous if on dry pavement. BTW, I found it out in 1969!

Yep many 4WD do that. Just have to back up and they'll pop right out for you. Even my old M151 use to do that on occasion.

That’s funny... RIP little Rattle

[ColoradoSpringsRob]

Can you tell us what shocks you used, and where you bought them? Glad that snake lived long enough to see a M715. His life was complete.

Looks good Brian! Keep that truck rolling.
