Here it is! My newest acquisition.. A 1973 Pinzgauer 710M

Image

I have been wanting one of these for years and finally found one. The reason I have wanted one primarily is obvious, because it's Massive and its AIRCOOLED!

The name for it is "Pinzgauer" (named for the breed of a thoroughbred European Horse) and it is one heavy duty, super engineered well built animal! The Pinzgauer is made by SDP in Austria (Steyr Daimler-puch) and it has one hell of a lot of similarities of a VW. The vehicle was primarily made for the Swiss Army, but many other European Military units use them- they are still in use today in Europe. The engine is an inline 4 cylinder 2.5 liter beast that makes a TON of down low torque. Here are some of the specs for the vehicle for those interested in knowing more about it.

MECHANICAL FEATURES

Four wheel drive with independent suspension and coil springs.
Central drive shaft is protected by a central pipe and not exposed.
Gear reduction 2:1 wheel hubs to gain ground clearance
Ground clearance 19 inches at lowest point with vehicle empty, 16 inches when loaded.
5 speed full synchro transmission made by ZF in Germany (Hi/low range for a total of 10 speeds forward and two reverse)
Vehicle capacity is 10 soldiers with rear seats in upright position.
The rear seats fold down flat to make an aluminum truck bed for cargo.
The cloth tops, roll bars, and stays remove quickly to make vehicle into a pickup.
The front window folds down. The door windows remove.
Max cargo weight is 1.1 tons, amazing for a 4300 lb weight vehicle. and can tow a whopping ELEVEN THOUSAND POUNDS!
Three hydraulic levers on dashboard enable four wheel drive and differential locks at the drivers demand
Twin batteries are installed in a slide out plastic tray in an outside metal box.
The second outside metal box on the left side contains the tool kit
The shovel is mounted below the tool box.
A jerry can frame is mounted on the right side.
The axe is mounted below the passengers legs.
Two rifle mounts attach to the passenger grab bar.
A battery disconnect switch has a removable key for maintenance.
The light switch allows 4 military blackout (masked) light positions, or 2 normal positions.
Blackout masked headlight is mounted in front grill.
A metal screen with door is mounted behind the driver to keep flying objects from hitting the driver.
Head bumper and knee bumper pads are installed.
Vehicle is undercoated, and all box tubing in frame is interior coated with wax.

GEARING AND SPEEDS

Five speed full synchromesh 5.33:1 TO 1:1
Reduction hi-low gear box full synchromesh .88:1 OR 1.69:1
Axle drive has spiral bevel gears to bevel differential 2.846:1
2.266:1 reduction spur gear hubs on each wheel.
Hydraulic actuated differential locks on all axles can be engaged or disengaged while driving.
High Low transfer case gives 2 Mph max speed in lowest range
Highest speed in high range 62 Mph with stock tires.

SUSPENSION

Independent axles with no leading or trailing swing arms.
Progressive acting coil springs single front and dual rear (710M,K), leaf springs rear (712M,K)
Additional hollow rubber overload springs inside of coil springs.
Spring elongation 200 mm max.
Single double acting shock absorber at each wheel.
Single woven steel wire rebound strap at each wheel.

ENGINE Image

2.499 Liter 4 cylinder air cooled in line gasoline engine.
Bore 92 mm
Stroke 94 mm
Compression ratio 7.5:1, horsepower 87 DIN, torque 177 Nm.
Octane requirement 87
Five bearing crankshaft
Twin Zenith or Solex 36 NDIX dual carburetors derived from Porsche
Gas consumption 15 mpg on flat highway.
Oil capacity 7 liters, 6.5 at oil changes
Pushrod design of engine is similar to that of a Porsche, but is horizontal inline.


On the highway top speed at the present is about 65 MPH, after that the gearing just runs you out of RPM and you take the rsik of overhating one of the reduction gear boxes in the outboard ends of the axles.. It is street legal and it does get some serious attention on the highway!

So.....Just what the hell is Jake gonna do with this monster??? DRIVE IT! In the mean time I have located a couple of core engines that I want to grab and tear into to see just what can be done to add a little more spice to the beast.. First in order is a set of 100mm Nickies, Charles has already agreed to make me a set! (3 liter baby!)

But right now I'm converting the ignition over to civilian arrangement (not quite so waterproof but easier to work with- I don't plan on driving it submerged anytime soon)and changing all the gear lubes in the tranny, diffs and reduction boxes and then build a console for a full set of gauges and thats about it for a good long while- I have too many "projects" so I'm just gonna run this one till she drops or until I break something.

And yes, it will literally go anywhere, I have already had it on two wheels and torn down a few trees climbing the side of the mountain with it.. I'll try to get some in action pics tomorrow and post them!

BTW- It looks like the 3 Liter TIV would bolt in pretty easily- Oh no! :shock: [/img]

Here is a front view of the beast..
Image

And yes it does have a *911 style* axial cooling fan to keep the engine cool.... BUT the air from the front of the vehicle is force fed directly into the fan, just like the VW Gol. The fan is 3" larger than a 911 fan and is driven at a very high ratio compared to a 911.

Image

Here is the driver's foot well area.. You can see the gearshift and the high and low range selector for the tranny..

Hell, I like this beast better than either of my Porsches!

Check out this 1972 factory Pinzgauer video... Its cool

:shock:

Sweet............it's an Offroader! :P

Edit: taking a closer look I can see some design differences I like over the US spec M813/92* 5 ton trucks, like the reduction hubs adding ground clearance (like a Hummer) the thoughtful compartments for equipment, and just the overall lighter weight of the Pinz. By way of comparison the unladen weight of a current model Army/Marine 5 ton truck (larger version of the "Deuce and a Half" or "6 BY" to old timers) is just over 22,000 lbs.

WAY COOL TOY............er,..........SERIOUS WORK TRUCK JAKE!!!

In-Action pics please!!!

My dad has two customers with the samestyle Pinz that we maintain/repair at our shop. One of the main Pinz parts importers lives here in Idaho. I have a small baja test run behind my shop and the Pinz is fun to play with. They turn SHARP.

Yeah, the turning radius is unbelievable..

Brent and I looked at it today and it looks like with enough work a Bus could be modified to fit on this drivetrain... That would be the ultimate Westy!!! The Bus is actually both wider and longer than the Pinz!

A guy that lives somewhere close to me has one. I see him driving it around on weekends and some weekday afternoons.

Similar to the unimog which is another ultimate 4 x 4

Haha, that truck makes all other cars look good :lol:

The 911 fan is kinda funny too for you to be driving that on an aircooled 4-cylinder :wink:

Is the fan made from some sort of plastic Jake?
Does it also has the alternator inside?

Nice buy! Couldn't you fit some straight axles like they do with older T1 busses? That would give better gearing with an uprated engine :roll:

Tnx,
Walter

Wally, The fan is nylon and the alternator is not housed inside the shroud like a 911..

Straight axles would waste all that wonderful ground clearance that I bought it for.. just wait till you see how rough it is at the "bottom" of the hill.... I damn near flipped it yesterday morning just climbing up the back side of the hill.... I should have locked the diffs first before trying that one...

Well, with this set-up, you don't have to worry about the left bank of cylinders getting too hot haha! :lol:

Ah, gotcha! Didn't think of that...

Hehe, learning to drive the thing huh :lol:

BTW: Those valve covers look a lot like those of a VW/NSU K70

Have fun with it, but don't kill yourself rolling it!

Greetings,
Walter

jesus the germans are very crafty people. Jake you have got to develope the 911 fan for the t4 engine. I wonder if Sandeep saw this already, how is his experiment going.

YEAH, BABY, IWAS RIGHT ON!!!! :D

Nice ride Jake, guy here at work has two and I am trying to get hin to sell one! :wink: Let us know how it drives and how is the fuel economy.

Are you going to stick a Massive Type IV into it! LOL :lol:
