I think it is stored in a big secret warehouse next to the Claymobile.

BTW...Does the diff of a AGL-4 require GL-4 oil?

The manual trans with the brass blocker rings is the only thing that needs the GL-4 gear lube. If you have an auto trans the diff can take the GL-5 gear lube.

Anyone that wants to order any GL-4 gear lube can do so from Amsoil.com look under the manual trans fluid. When they ask for a referring dealer you can use my number 503903.

Looks like something one could build.

AGL 4 has never surfaced...presumed scrapped
Gamma Goat has never surfaced...presumed scrapped
Dynatrac (CL-91) - many surviviors..

AGL-4
Pronounced AGILE 4 or Articulated Ground Logistical 4 wheel drive transport was a prototype cargo hauler being tested for military and civilian use. The AGL-4 was based primarily on the Corvair Forward Control Loadside uni-body platform. The front or main section of the AGL-4 was self-powered and could be driven without the attached rear section by attaching a small set of dolly wheels to the car section. This allowed the AGL-4 to pick up and drop off loads without having to wait for the rear section to be unloaded. The cab section tilted forward for easy access to the engine for service and repairs.

While the AGL-4 was hauling the loads the rear section also provided drive power allowing the vehicle to traverse steep terrain or travel across loose and slippery soil via the 4 wheel drive and large aggressive treaded tires. The front and rear sections were attached via a common drive but the connection joints allowed for movement in nearly every direction. The two sections could keep all 4 drive wheels on the ground regardless of the dips and twist through it ability to rotate and flex at the connection point.

Unfortunately it would appear that the AGL-4 was ultimately not selected for final design approval but the technical premise was continued to be developed through additional articulated prototypes and eventually lead to the development of the M-561 Gamma Goat and the CL-91

The Gamma Goat:
The M-561 Corvair powered prototype Gamma Goat. This all-terrain vehicle could operate in with just the 2 center wheels for good fuel economy or with all 6 wheels driving for serious all terrain traction. This prototype was powered by an 80HP Corvair motor circa 1960-61 at the MD proving grounds. Eventually the military choose a 3 cylinder diesel motor to power the final product.

The Dynatrac (CL-91):
The CL-91 was a multi-terrain, high mobility tracked vehicle consisting of two or three units connected by articulation joints which permitted displacement of the units up to 30 degrees from the centerline in any plane. A single 80-bhp General Motors Corvair air-cooled engine drove all units.
The CL-91 could travel at up to 50 km/h (30 mph) over snow, mud and muskeg; and, thanks to its relatively lightweight construction and 20-cm (8-in.) freeboard, it could swim at 3 km/h (2 mph) with a 900-kg (2,000 lb.) payload. In deep snow, with a full payload, it could tow 12 ski troops or an 1,100-kg (2,400 lb.) toboggan, and negotiate a 60 per cent grade and a 40 per cent side slope.
Of a total of 63 Dynatracs produced, 57 went to the U.S. Army, two each to the Canadian Army and the British Army. Two were used as test vehicles.

How about the Lockheed TWISTER?

Never surfaced, presumed scrapped...

Maybe calling the AGL-4 a Gama Goat predecessor is assuming too much. The combination of Corvair six-cylinder engine and articulated joint doesn’t necessarily lead from one to the other, especially considering the fact that GM itself was behind the former and Ling-Temco-Vought built the latter. Besides, there was at least one other Corvair-powered articulated multi-wheeler built by yet another firm for the military: the Lockheed Twister.
Like the Gama Goat, only the prototype of the Lockheed Twister used Corvair power, though in this case it used more of everything: eight wheels and dual 164-cu.in. Corvair six-cylinder engines, each running through an Allison TX-200-2B automatic transmission. Oddly, the engines sat beside the transmissions in each unit and transferred power through multiple V-belts; the transmissions then sent power through a front-mounted transfer case, which then sent power back to two differentials.

Built in October 1965 and extensively tested over the next three years by Lockheed, the prototype opened the door for a $3 million contract with the Pentagon for the production of test vehicles. Crismon wrote that the Twister “performed admirably under all circumstances;” it could easily hit 65 MPH, and the coil-sprung suspension allowed 12 inches of vertical wheel travel.

The later, larger (10 tons vs. 5.5 tons) version of the Twister that the Army tested in 1971, the XM-808, dumped the Corvair engines for two 291hp Chrysler 440-cu.in. V-8s. Three prototypes were actually built for the Army, one of which was outfitted to test the Twister’s amphibious capabilities. Crismon wrote that the XM-808 also performed well in tests, but “as a scout vehicle it was overkill, and the maintenance and cost aspects associated with the dual power train arrangements were impractical.”

At least the larger prototype still exists, on display at the Detroit Arsenal in Warren, Michigan. And all was not for naught for Lockheed when the military terminated the project: Much of the technology went into Lockheed’s Dragon Wagon 8×8 cabover truck.

The Twister prototype was scrapped by Lockheed. I know, because I bid on it - I wanted the twin 140 motors. Somebody else bid more than I did. I got to sit in the drivers seat. I have a Twister drivers license. It was not a runner when it went to scrap. For many years, that vehicle held the lap record at the Nevada Test Facility, an off road testing facility near Reno. At least a couple of the engineers on the prototype were Corvair enthusiasts. If you look up the SAE paper on the twister, the author is Ward Brannon, a many year member of Silicon Valley Corsa in San Jose.
The Vought website mentions the Gama Goat and states the Prototype was restored in 2007 after being bought by a tire company owner. It might be on display somewhere.

It's a bummer that the twister was scrapped. Sure would be great to see some pictures of the restored Gamma Goat. It's a real shame that so many military prototypes are scrapped when the projects are abandoned. At least someone managed to save the Corvair Tank.

Seth, regarding the Vought Gamma Goat prototype reference, any idea if that was the Corvair powered prototype or the prototype of the 3-cylinder diesel version?

Nevermind, I found the reference...

Late 1980’s M561 vehicles finally phased out of military inventory. While the production version of the Gama Goat proved to be a highly mobile vehicle, it was beset by mechanical problems, excessive crew cab noise and the need for special driver training due to the vehicles unique handling and steering characteristics (steering was not self centering). The Goat was ultimately replaced by the more conventional M998, 4X4, High Mobility Multipurpose Wheeled Vehicle (HMMWV). Nevertheless, the importance of vehicle articulation and independent suspension with high suspension travel combined with relatively wide, large diameter, low pressure tires did have a positive and lasting effect upon future military vehicle designs.

A number of surplus M561’s were bought and restored by private individuals. There is a real cult following as evidenced by the referenced Gama Goat web site which is the conduit for information for these enthusiasts.

May 1980 Roger Gamaunt sold Corvair powered prototype to author for one dollar and other considerations. Author picked up Prototype Gama Goat in Fawnskin, California and transported it to Reno, Nevada where it was used as a support vehicle in tire traction testing (authors testing company) for several years. The vehicle which had been stripped of all paint when picked up was finally repainted olive drab when it was retired from other duties. A refurbishment was completed in 2007 and the vehicle and all associated documentation await a permanent home in some suitable museum.
