M985A2 HEMTT w/M989 HEMAT build
Posted by HeavyArty on Monday, January 31, 2022 9:15 PM

I started on another project I have been wanting to do for a while. I am building an M985A2 HEMTT w/M989 HEMAT (Heavy Expanded Mobility Ammo Trailer).

This combo was used by MLRS Bns as ammo carriers. They held eight MLRS rocket pods; four on the truck, four on the trailer. This was the configuration we used in 1-39 FA (MLRS), 3ID during the invasion of Iraq in '03, which is how I will depict it. They have since been replaced by the M1120 LHS as ammo trucks in MLRS Bns.

 

The main differences in the truck that make it an M985 is that the rear crane has an added block and tackle that increases the capacity from 4500 lbs to 5400 lbs. There are also added foot holders and tie downs in the bed to secure the MLRS pods.

M985A2 1

 

I am using most of the parts from the Trumpeter M983A2 tractor (# 01055 with the M870A1 trailer), frame rails from the Trumpeter M1120, and the load bed and crane from the Italeri M977 kit.

So far, I have the frame done. I had to add about 3/16 of an inch to the rear of the M1120 frame (under the crane mount, so unseen) so it would equal the length of the Italeri M977 frame. All other parts of the frame lined up.

I modified some areas to match the real deal as opposed to how the model companies think they are. First, I tilted the transfer case rearward so it lines up w/the engine. I also changed the first and last axle to have a non-geared central part. Only the two inner ones are geared so the prop shaft can continue on and power the outside set of axles. I also had to lengthen the prop shafts between everything now that the angles were changed.

Here are some more pics that show the mods. I also added all the torsion bars to the axles as well. The kit only includes the two from the frame to the rear axles.

IMG_1884

For the non-geared axles, I cut off the kit part and added two non-geared centers from the Meng M911 kit. I had ordered a sprue that contains the load axle to build my M920 a few years ago and Meng sent me two of them by mistake. Each had one non-geared axle for the rear of the truck. I cut the covers off these axles and added them to the M985 axles.

Front. The M983 in the set w/M870A1 has been updated with a new sprue that also contains the front air brake parts that were missing from the earlier M983A2 tractor kit.

The basic M983 kit also contains the steering gear boxes and all the linkages. These allow the steering to be positionable and are very nice.

That’s all for now. More to come later.

HeavyArty, this is a project that I can sink my teeth into!  The HEMTT truck are made right here in my hometown of Oshkosh, WI along with the MRAP and others.  They're always test driving them around our town so it's great to get some up close looks at them.  I've always wanted to build a model of each of the vehicles that the Oshkosh Corp. makes for the armed services.  I've slowly started colecting the various kits and hope to get started soon.  I'll be following your build closely.

That's super cool Gino! Neat to have all the extra information to superdetail the kit- I'm lucky to finish one right outta the box. Looking forward to more!

I currently have the m983 and patriot launcher waiting for paint when the weather warms up. I'm gonna tag along to see how you paint the interior.

Work on the M985 continues. I basically have the rolling chassis done. I added the fuel tank, BII box next to it, and battery box on the opposite side from the M1120 sprue. They are more detailed than what comes in the M983A2 kit.
IMG_1923
IMG_1912
IMG_1922

On the rear, I added the stabilizing legs for the crane. I extended them by cutting off the outer leg sections and adding the telescoping square tubes out of square stock styrene.
IMG_1913
IMG_1914

I also added some additional details to the rear crane. The actual crane boom has three sections that telescope out to give it more reach. Italeri molds it with the second section fully in, and the third section extended. To make the full three sections workable, I followed Michael “165thspc” Koenig’s recent article on “Detailing that Italeri HEMTT Crane”.

I added the second section and filled in the underside gap. I added holes on the mount and a square section of tubing as a rest for the upper crane. I also added new, longer actuating levers on the control panel. Next up is adding some hydraulic lines.
IMG_1915
IMG_1916
IMG_1917

I have also completed the cargo bed. I added the foot holds for the rocket pods from 45 degree angle iron styrene, and added the tie-down loops from styrene rod.
IMG_1919
IMG_1918

I also completed the engine cover with radiator, which will be added after the engine is painted, and the muffler assembly.
IMG_1920
IMG_1921

Next up is the cab. It is very detailed in and out.

I have added all the hydraulic hoses on the crane. There are quite a few. I used 0.20 styrene rod for the fixed ones, and thin wire for the movable ones.
IMG_1925
IMG_1924

I also finished the construction on the cab interior.
IMG_1927
IMG_1926

The truck is pretty much done with construction. I need to start painting it next. The subassemblies need to be painted, then assembled, and interior decals and details added. For now, I will set it aside though.

I have moved on to the trailer. A while ago, someone on Armorama (sorry, I can’t remember who it was) was selling a started M985 w/M989 HEMAT and M26 launch pods. It went too fast and I missed it at the time. I was able to buy the M989 and launch pods from the guy who bought it at the time, thanks Brett.

I have taken the started trailer and added to it. It was only the load bed, tongue and light details started, along w/the sides of the bed (I removed the sides).
IMG_1928

I added the frame underneath from C-channel styrene. I also added a left over spare trailer tire mount from the M983 kit. The trailer spare sits on the work platform on the truck.
IMG_1929

I will be using modified springs left over from a HEMTT and rods for the suspension. The tires will be the Def Model tires for the PATRIOT trailer. They look right to me and are the correct size. I will be using pieces cut from the container in the M915 kit for the sides of the bed. They have the correct corrugated look and are the exact length needed.
IMG_1930

More to come in a couple weeks. I’ll be on vacation next week; going to meet my new grand daughter (GD#2).

Hello Gino!

Congratulations on the granddaughter (more important) and the model (still very cool, too!). As the various kit show this truck isn't as easy to model as some might think.

One thing that amazed me for years was how crappy the Italeri HEMTT was and how none of the reviewers ever mentioned it...

And now for years there is the newer version of HEMTT with air ride - does anybody make a model of that variant?

Thanks for sharing, good luck with your build and have a nice day

Thanks Pawel.  The HEMTT is fun to model and can be super-detailed if you want to.  It leaves a lot to be improved.  

Pawel

That is the A4 version and unfortunately, has not been offered in kit form. 

However, you can piece one together from parts at Shapeways.  It is mainly a different engine compartment layout...

https://www.shapeways.com/product/MBGBHJNG8/1-35-scale-hemtt-a4-piggy-back?optionId=67304373&li=marketplace

...and the new pneumatic suspension units, x4.

https://www.shapeways.com/product/A8DYSRFNT/1-35-scale-hemtt-a4-suspension-kit-ad-130?optionId=119151122&li=marketplace

The cab is also longer and would need an extension at the back, like I did on my M1074A1 PLS.

Work on the M989 HEMAT continues.

I added the NATO tail lights to the rear and a few more reflectors (2 clear ones to the rear and two more on the front).

 

I also completed the suspension. My original plan to use HEMTT springs didn’t work out as they were too short and didn’t give the right spacing between the wheels. Meng came to the rescue again. On the two M911 sprues, there were springs for the front axle. I used both sets to make up the HEMAT suspension, along with some scratch-building of the mounts and styrene tubing for the axles.
IMG_1932
IMG_1931

On the topside, I added the footholds for the rocket pods and some tie-down rings from a 3D printed set from Shapeways.

IMG_1933

I also built the side panels out of the side pieces from the 40’ container in the Trumpeter M915 kit. The ones on the left show the inside details and the ones on the right show the outside details.
IMG_1934

Next up is to assemble the side pieces (one side down for loading) and finish the hinge and latch details on them. Then it is onto the tongue, hitch, and landing leg.

This one is getting close to being built and moving on to painting.

I have finished building the HEMAT.

I added the side panels and the hinges for them, along with pins holding them together and four tiedown loops for a canvas on each panel from thin wire, bent into an upside down J.

IMG_1936
IMG_1937
IMG_1938

 

Here it is with the one side taped on to show the side panels down.
IMG_1940

Then I moved onto the front with the BII box cover on top of the tongue and the landing leg. The leg is a couple different sizes of square tubing and sheet and rod styrene and a left over piece of PE runner for a holder for the handle arm. I also made the lunette ring out of thick solder, wrapped around a paint brush handle to get a good round shape.

I also built the MLRS rocket pods, all eight of them. I added the transport feet from thick styrene bar. This is only four.
IMG_1941
IMG_1951

You may see that one of the above has a device used to connect the hoist hook to. I built this from a piece of sheet styrene, a piece of angle iron, and a couple hooks from the Dragon kit LLM hoist. The issue with this is that the plastic pods are not balanced and dip in the front when suspended.
IMG_1943

To fix this, I added 8 grams of lead fishing weight, flattened out, to the underside rear of the pod.
IMG_1946

Pretty closely balanced; good enough for government work.
IMG_1945

Here is a mockup of how it will look.

Next up is the paint booth.

I added a few more details to the stabilizing legs for the crane tonight. I had a couple of base plates left over from a PE set and added them, along with scratch-built pin supports to attach them to the legs.

I have completed the cab interior painting and detailing. I mostly used the kit decals for the cab, which there are a lot of. I added a couple waring and general placards, but only a few. The kit is very detailed inside the cab.

IMG_1961
IMG_1958

The only thing I added is a resin SINCGARS ASIP radio mount and handset. The kit comes with a radio mount, but I am not sure what radio it is supposed to be. It kind of looks like a SINCGARS mount, but not really. That is why I switched it. The speaker box comes in the kit. I fully wired the radio parts as well w/ 0.015 fuse wire.
IMG_1959
IMG_1960

The kit also included placards for the driver’s door and a serial number that goes inside both doors. Here are the completed door interiors.
IMG_1962

I also completed the engine. I added some wires/hoses to give it some extra details. Most of it will not be seen, but I know it is all there. You mainly only see the back side of the engine since I left the side access covers closed on this one.
IMG_1964
IMG_1963

Next up is overall paint color. Hopefully I will get them into the paint booth this week.
