I'm guessing by the lack of response the New Mil-Spec Mack tractor went no place . . .

In the commercial that is posted on the Mack website does it looks like they have the MP8 mated with an SST transmission?

A few Years before they introduced the Granite military trucks (just before they discontinued the RB chassis) they were working on an electric/diesel hybrid vehicle for the US Air Force. I think they later had one they were building for the US Army.

I have personally seen some of the GU813E chassis (no pictures though) and the engines are void of emissions control items.

Looked back at the video and saw that it isn't an MP8, it's an E-Tech, with the SST bolted to it.

Very, they not only bought the heavy haul tractor they took 3 other truck as well . . .

Is back in the Military

Lots of engine power and Low gear ratio's they are set to walk the line with pride as they once did

Sweet, So Mack has got plenty of variant's set up and stand at the ready to make any truck into what ever truck they need . . . 4 truck's becomes 8 truck's or 12 trucks

The armored line haul tractor uses an export version of the MP8 engine that has no emissions aftertreatment. I beleive this vehicle was supposed to be part of an open competition to replace the armys line haul fleet, but the competition was pushed out due to budgeting issues by the army. There are some other military vehicles like troop carriers, and wreckers, etc that have been sold in europe, south america and in support of the war in iraq/afghanistan. They look like some pretty neat trucks...wonder if the military group has any other new projects going on? Anybody hear anything?

[B61TENDT711]

Yes they got some new iron up for testing, AM-General is doing a Joint venture set of Rigs.

New Rig's:

To me it looks like a blend of AM-Generals Humvee and IHC/OshKosh's M-rap

So, if all goes well it be AM-G & Mack supplying the military its Rig's and that is one tough pair to beat

I've been told by my Detroit Diesel Rep. that the Military is still using the 8V-92's in all of there big haul tractors like the Oshkosh with the Allison Trans. I'm told the new ones being built are over 500 Hp. & the reason for them still using this combo ? The parts all interchange and the motor is compact & light. I don't know, what do you guys think ??.

BULLHUSK

[james j neiweem]

Are they still building Detroit 2 cycles? I thought they were long gone.

[bullhusk]

From what Detroit Diesel tells me, YES there's A company building the motors an parts for the 71-53 & 92's under Detroit's name. As you know Uncle Sam has 10's of thounds of 2 cycle motors still in service & because of there parts diversity they still like to use them. BULLHUSK

[B61TENDT711]

2 things way they still use them.

1. They cheap, not good not bad just plan $ wise cheap.

2. If it ain't broke don't fix it, why R & D a new Prime mover if the old ones are still dong the work . . .

Mike

[bullhusk]

Agreed,

I love em the 71's & 92's call me crazy but I'll run a silver 92 for as long as I want to, granted I'll have to keep my eye on the bottom end, maybe 250 to 300,000 do rods & mains something you did dot have to do on the 71's but if you have a 3406 A or B or a 335 cummins you would have to do the same thing no ?

The military likes standards. The 8V92 was the original specification for the M1070 HET (Heavy Equipment Transporter) as well as the HEMTT and the PLS. Today they are supplied with Cummins engines and I also believe some of their truck also come with (Or did come with) CAT's.

I don't think they like to upgrade engines on older trucks because of cost, labor and training. A grunt who knows how to turn a wrench on an 8V92 is valuable and keeping things consistent is important to them.

As far as 2-cycles go? so many have been made and are still in service that parts for them will be available all the way to 2040. I dont know if that is true but I remember readin it a while back that DD will keep the 2 strokers going as long as people are running them. But with enviro regs the death of 2 cycles could come allot sooner.

One of the bonuses of the military equipment is that they don't meet enviromental regulations. Add to that the lack of electronic engine controls and the ease with which they can be reoriented for rotation and you have a pretty versatile combination. Don't they also start easier too?

Here's a recent press release from Mack

United States Marine Corps Taps Mack

GREENSBORO, NC, (October 21, 2010) – The Mack Military Group within Mack Trucks, Inc. was recently awarded a contract in support of the United States Marine Corps (USMC) Buffalo A1 Mine Resistant Ambush Protected (MRAP) vehicle. The contract calls for remanufactured engines and new transfer cases to be used in Buffalo MRAP repair and reset efforts.

“At the heart of every Buffalo A1 is a Mack truck,” said Ryan Werling, director of defense sales and programs for the Mack Military Group. “Nearly the entire powertrain, electronic architecture, and cab interior are derived from our rugged vehicles and are a true testament to the durability of our products. With the Marine Corps being a major owner and user of Buffalo A1s, we are committed to supporting them in any way we can.”

Deliveries will start later this year and continue through the first quarter of 2011. The total value of the contract is approximately $1.3 million.

Well you beat me to it rhasler I was going to mention the buffalo...oh well. The Air Force has ordered several of the Hybrid Granites and the Army has ordered several huge orders of Vision/pinnacle tractors. Maybe an order for the armoured line haul Granites is next.

Its quite amazing to look at such a huge trucks, looking at the history of mack trucks in the military. It is just amazing.

We are currently running an order for the US Army. There are only a few trucks on the order. I don't know the plans for them.

We also just built a few more trucks for Iraq.

Mack has not produced a true military spec truck since the 10-ton M123 tractor and sister M125 cargo truck.

Mack produced approximately 4,000 10-ton M123 prime-movers and 550 of the M125 cargo body version.

Owing to the truck’s impressive ability, and for lack of finding anything better, the army used its M123’s for decades. Of the two most produced variations, the original M123s were built from 1955-1957, while later versions from 1965-1969 were powered by Cummins V-8 diesels.

The earlier M123s were unique in that Mack decided to use LeRoi (famous for air compressors) model T-H844 V-8 gasoline engines. Because the LeRoi-powered units made a distinctive muscular throbbing sound owing to their unusual cylinder head design, soldiers knew by the sound what truck was coming around the corner. The truck’s tall 14:00-24 tires also gave the Mack a massive appearance unlike any other M-series military truck.

• M123 FSN 2320-395-1875. Dual rear winches. LeRoi T-H844 V8 Gas engine.
• M123E2 FSN 2320-879-6177. Dual rear winches, Cummins V8-300 diesel.
  
• M123C FSN 2320-294-9552. Single rear winch. Cummins V8-300 diesel.
  
• M123D FSN 2320-542-2509. Dual rear winches. Cummins V8-300 diesel.
  
• M123A1C FSN 2320-226-6081. Single rear winch, 36,000lb lift crane. Cummins V8-300 diesel.

By 1973, the U.S. Army’s 10-ton Mack M123 fleet was aging. A new and larger replacement was desired. After testing two prototypes from Kenworth (XM523 and XM523E1), the army tried the International Harvester XM523E2 (based on their model 8066 off-highway truck) as an interim solution, but encountered excessive maintenance problems. It was removed from service after just 5 years.

Mack then put forth several proposals including the 25-ton F-897ST.

Engine: 375hp ENDT866 V-8
Transmission: 12-speed TRTXL107
Wheelbase: 178 inches
Tires: 14.00x24
Curb Weight: 32,970 pounds
GVW: 102,000 pounds
Winch: Braden 60,000 pound mounted behind cab

The army also tested a 6x6 F-8976SX (as sold to the Moroccan military) and a 6x6 DM-8976SX, both equipped with the same ENDT866 powertrains.

Although the U.S. Army was completely satisfied with the cross-country ability of the manual transmission-equipped 10-ton M123 while pulling M-60 tank ladened trailers, the army felt their test drivers could not shift gears fast enough in the prototype 25-ton Mack tractors under the same conditions. A decision was made to transition to automatic transmissions. However, rather than having Mack resubmit proposals with Allison automatic transmissions, the army gave the business to Oshkosh with their Allison CLBT-750 equipped 25-ton 8x6 M911 (commercial known as the model J-2065).
