Back (more or less) to the main topic:

I was lucky enough for find one of the old Eduard etch sets on eBay. It is intended for the old Italeri Fuel Truck kit. Tonight's progress was to add the Oshkosh marked mud flaps from that set to my LHS vehicle.

I also installed the rear cable guide fairlead that comes with the new Voyager HEMTT etch set for the semi-tractor.

Michael, what you're actually seeing on that axle, is the tire being pulled in that direction. On all trucks/trailers that have multiple non-steer axles, they tires will be "drug"/"pulled" during a turn, especially while it has a load on it. Depending on which way the vehicle is turning/backing, you'll notice the non-steer axle/tires... I don't know how to word it.. Maybe offset?

You can see it here for example.
Sorry I'll have to post the picture when I have a better signal.

But Dustin the point here is that this is a "steering" axle.

My appologies. I misread that.

No problem!

Sorry for taking us off topic. Seems like whatever thread of yours that I frequent, we always seem to leave your topic and just start talking trucks in general. Lol

Hey, I want to learn about the MK23 as much as anyone, so for my part, I'm good with these alternate topics!

Something we might all be interested in regarding the Mk 23:

I tried something last night - since I cannot access the Oshkosh Defense website directly without clearance, I tried the Pierce Fire Equipment site. (Pierce is one of the Oshkosh fire equipment divisions.) It seems the TAK-4 suspension/rear steering system is also used on many of their heavy fire trucks.

Good score! That certainly helps with the modifications.

Any idea how it works? Lol

Is the left box receiving hydraulic pressure from hoses coming from the right box?

Taylor, that was my question also. It must be a hydraulic connection similar to the two steering gear boxes on the HEMTT.

The Pierce literature says it is mechanical/hydraulic with no electronics.

Something of possible HEMTT interest: - Early add-on cab air conditioning unit.

Nope, that is how it was designed to mount. It is a similar system to what was mounted in the first generation up-armored HMMWVs w/ASK.



It was the inside part of the below Red Dot system.

Gino:
Good find pic

OK, In the future I will refrain from freelancing and editorializing on designs I don't yet understand.

No excuse but the two wide open square A/C air outlets in the HEMTT blowing directly towards the windshield did not seem to make sense and made me think the unit had been installed improperly.

Fantastic reference photos you found there Gino.

Mike! You and Gino ARE AMAZING what with all your reference material and detailed builds!

Gino, to your knowledge, does anyone offer that Red Dot Corporation add-on A/C system in 1/35th?

Pro Art did.

They is still one available on eBay though.

So sad about Pro-Art.

Now that you have sort of shown me what to search for it looks like Pro-Art also made the AIRCO/Red Dot Corp units available separately and in four different mounting styles!

Yup, I didn't see any of that set on eBay though. Good luck finding it.

The exterior compressor box wouldn't be too hard to scratch. I bought a set of HO train fan covers that would fit the bill perfectly (still haven't built one yet). The inner box doesn't look too hard either.

Agreed, I was thinking the same thing - a couple of HO diesel hood fans might work.

Sidebar update on the Mk 23 truck:

Recently ordered two kits of the 23 at the same time to save on shipping but only received one - that in itself is a kick in the pants and the wallet!

Having now looked at the one kit I can share that on the MK 23 only the front axle steers! However, the TAK-4 rear non-steering suspension units are constructed using the same parts (more of less) as the forward steering unit and it should not be too difficult at all to modify the rear axles to add the steering equipment.

A single kit will give you three axle suspension units, two steering gearboxes, (both needed for the front axle,) two simple differentials and one pass-through differential.

Two kits will give you more than enough parts to build either the four axle 8x8 Mk 23 LHS steering & suspension OR the electric hybrid 8x8 HEMTT A3!

Just an F.Y.I. - Overall this model has excellent detail and style. It is a shame to waste the cab and chassis on a conversion. It is going to be extremely difficult to talk myself into building the HEMTT A3 rather than the 16.5 ton, Mk 23 LHS!

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Yup the Mk. 23 is a beautiful kit. It's on my Christmas wish list.

Here you go !

Mike, I will be very happy to watch you take the lead on the 16.5 LHS! Another great build is on the way!
