ranchhopper Posted August 8, 2017 Share Posted August 8, 2017 I was really surprised to see this for auction 123s are rare to begin with but a mack 123 is a rare bird indeed. I wish I had the means to move it these are almost ten feet wide though and driving them can be a challenge.https://gsaauctions.gov/gsaauctions/aucitsrh/?sl=71QSCI17417013 Quote Link to comment Share on other sites More sharing options...

HeavyGunner Posted August 8, 2017 Share Posted August 8, 2017 Wow that things pretty neat. I'm assuming it has all Mack running gear? Any clues what engine other than diesel v8?

57 bcr Posted August 8, 2017 Share Posted August 8, 2017 One of those sat out at Maggio's in Rockford for years. Don't know what ever happened to it. It was rough from just being left outside for a long time. Always wondered "why a 903 ?". But after learning how many 903's the government had in operation at the time,It answered my question!

ranchhopper Posted August 12, 2017 Author Share Posted August 12, 2017 They used 903s in some of the ten tons and in boats. Quote Link to comment Share on other sites More sharing options...
41chevy Posted August 12, 2017 Share Posted August 12, 2017 They used 903s in some of the ten tons and in boats. The Bradley, Marine AA7Va1 the MLRS and M-41 run them too.

terry Posted August 12, 2017 Share Posted August 12, 2017 (edited) I ran a rough terrain crane in Viet Nam, had the 903 in the carrier, and a 220 in the crane, we had to change the 903 once, that was a real job! terry Also seen alot of the 10 ton trucks with the 903 engine.

ranchhopper Posted August 12, 2017 Author Share Posted August 12, 2017 They sell lots of 903 parts on government surplus sites all new in the box they just sold off a pallet of exhaust manifolds brand new for pennies on the dollar. Quote Link to comment Share on other sites More sharing options...
BillyT Posted August 16, 2017 Share Posted August 16, 2017 I can't see the photo of the truck but the GM made "deuce and a Halfs" I saw at Ft Benning had 2 cycle Detroit's and I'm assuming Allison automatics. There was a noticeable pause between shifts and the driveline would "ring" as the shift was completed! They all did it, so I don't think it was wear. I was in a quartermaster company so I never got to see under one! Quote Link to comment Share on other sites More sharing options...
