Popular Post OFFROADRESCUE Posted September 29, 2015 Popular Post Share Posted September 29, 2015 Howdy all, So after a couple years of being in the market for a military wrecker I have found this and fell in love, but know little about Mack F900s. This is an F900 6x6 AWD powered by an ENDT866 V8. As far as I know this was built for the military during a contract competition and is 1/5 in existence. I have confirmed the VIN to being military, and it was originally OD green before it was updated for civilian use as a heavy wrecker. It ran when it was parked but has since deteriorated from lack of use and maintenance. Someone had done some troubleshooting in it and removed 5/8 injectors. It only had 18,000 miles on it and was wondering what the general consensus was on this this running again as long as no major mechanical defects are found. Also if anyone know more about this that would be great too!! Thx ahead of time.

Can't go wrong with it, worse came to worse you can re power it or rebuild it. 1 Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/41990-mid-70s-mack-military-wrecker-prototype/#findComment-305540 Share on other sites More sharing options...
Popular Post bbigrig Posted September 29, 2015 Popular Post Share Posted September 29, 2015 That's pretty cool. I'm just wondering what would be the difference from the F800's that were fairly popular for mixers here in Canada in the 70's? Would it be an F900 or an F800 like the 6 wheel drive mixers? The Pelletiers also had a 6 wheel drive F model tractor in the 70's. Great find. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/41990-mid-70s-mack-military-wrecker-prototype/#findComment-305544 Share on other sites More sharing options...

This I assume would be number 4 then with the suffix of 1004Sent from my iPhone using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/41990-mid-70s-mack-military-wrecker-prototype/#findComment-305593 Share on other sites More sharing options...

Freightrain Posted September 30, 2015 Share Posted September 30, 2015 Just noticed the bulldozer blade on the back. Guess that really helps it "dig in" and pull. 1 Quote Larry 1959 B61 Liv'n Large......................
