Something a bit different: progress on the M4, High Speed Tractor to go with the Ammo Trailer, 155mm and Mack NO on this fire support mission.
And yes, I cut the roof panels off and framed up the engine compartment sheet metal to better see the added detail in the engine area. There is also an engine access panel behind one of the seat backs in the cab that I opened up for yet another chance to better see the engine.

Open engine access panel seen from inside the cab. I plan on framing up the back of the missing seat back and leaning it against the other seats as though just thrown aside.
The bottom of the radiator on the model has five hose fittings, clearly the center one is for the engine cooling water. The two at the rear are for the engine oil cooler. The two to the front are for the transmission oil cooler. There should be four additional smaller hose lines running, one each, to these fittings. I figure the purpose of this access panel is to reach these bottom radiator fittings for maintenance. You cannot get to them from the rear b/c of the ammo box and fan drive mechanism and the only other recourse would be to lay across the engine and hang upside down to reach them.

Center water hose to radiator is not present in this photo. Also note the tensioning pulley (in O.D.) next to the fan drive pulley. (Missing from the model kit.)

Mike,
I know there isn't a plastic kit available for the Mack NO 6 but is there a kit that can give a good start to scratch building a NO6? I know you utilized the Tamiya Dragon Wagon with tons of scratch building but I thought maybe there would another kit that can be used, like the AFV 5 ton?
Thanks DJ

As far as I am aware the answer to your question is no.
Gino recently pointed out that the Tank Workshop wheels for their M123 are also correct for the Mack and for the post-war White 666 semi-tractor. Also the TW wheel drums are close to correct with just some slight modifications to the rear hubs.
I personally have never seen the drive line on the M123 so I cannot comment on how much it is or is not like the Mack but wasn't the M123 also built by Mack? So there could be great similarities there!
Perhaps Gino can chime in here with an opinion.

They were both built by Mack, but 20 years apart.
The driveline on an M123 has the same type as the M54/M35 in the rear (with geared diffs that have the driveshafts entering from above) and the same type as the M25 Dragon Wagon in the front (a large round diff with shaft entering from the rear).
I have not really looked into it, but I believe the Mack NO has diffs like a CCKW with the driveshafts entering from the front/rear.

I have to correct you on that one Gino, the Mack NO had the geared rear differentials as you describe with the driveshafts running across the top. Sorry cannot put my hands on a photo right now to prove it.
The Mack also had, at least a similar front differential to the Dragon Wagon but the pumpkin was off-center rather than being centered between the wheels.

The 10 ton M123 certainly looks like a slightly bigger Mack NO just with, what I will call, the Army's standard 5 ton cab installed.
By the way, someone on the Shapeways site is offering that top-feed winch in case anyone is interested.

Here we go - here's are photos of the rear differentials from the TM on the Mack NO:
The above images come from the collection of EASY 1 Productions - From the disc entitled "TM 10-1679; 7 1/2 ton 6x6 Prime Mover Mack NO"

Still cannot find a photo of the underside of the 10 ton M123!
I do have a bottom photo of the Mack NO. Somehow David Doyle found a real beauty and published it in his Allied-Axis book on the Mack.

You can sort of see the flat diffs on the M123 above. It has the same exact rear axle/suspension/diff setup as an M35/M54, just more robust.
You can see the large, round front diff above too.
If yopu want to scratch a Mack NO, I recommend getting in touch w/the Mack Truck Museum. I contacted them when I was getting ready to build my M123A1C and they sent me a bunch of pics and very detailed line drawings for it. I could not have built it as detailed as I did without their help.

The Museum's NO6 is soon scheduled to come out of the restoration shop and into the public display.

A very detailed and close-up walk around of the Mack NO recently posted on the "NET-MAQUETTES" web site:
https://www.net-maquettes.com/pictures/mack-no-truck/I believe this is the vehicle that was in the Littlefield Collection but the site does not say.

The 10 ton Vietnam era Mack. This one owned by Mark Austin.
Different from the Mack NO6 but you can clearly see the genetic heritage in the vehicle!

F.Y.I. - Mike Powell over at Easy 1 Productions, just last night told me his current disc covering the Mack NO Tech Manual now has about 200 additional images added from a walk-around he did recently at the Mack Museum in Allentown, PA!
Just sharing.

That is the former Jacques Littlefield Mack!
As to the Net-Maquettes offering: I have to say I hate the video format they have chosen here - slowly zooming thru still photos in a fixed order while giving us little ability to jump to what the viewer may be truly interested in, is a royal waste of everyone's time, especially when the real goal is to provide a "walk-around" reference resource.
For those with some familiarity in the Mack vehicle, who need to focus on specific details, this video moves like molasses in winter.
Please; give me a large display of thumbnail images that I can take in quickly, only clicking on those subjects that I am interested in and/or have need of seeing in more detail. (Like almost everyone else does it!)
Perhaps the disc offers both formats - of that I cannot say.
Sorry

Hi Mike
If you don't like the way pics are displayed on Net-Maquettes, just take a look at the original website(s) they're coming from. In the case of the Mack NO, it's svsm.org (once again...)

Hi, Mike and Everyone Else!
I STILL cannot get over that Mack NO6 of yours!!!
Question, regarding your M4 Artillery Tractor:
Is that an after-market "Canvas" Tarp over the Ammo Bin, or did you "fabricate" it on your own..?
Thanks,
-Dennis

That canvas is an after market item that originally came from Scale-Link in the UK. However I am not sure they are still in business any more.

I tried searching for Scale-Link on line with no success. Thought they might be out of business. Sorry.
Yes, better hurry, only 2 left in stock!
Thanks Frenchy
