mongothetrucker Posted November 20, 2012 Share Posted November 20, 2012 Hey, I have a Facebook group for Mack Fire trucks and a question has come up. I was always told the B model numbers were odd for diesel and even for gas. There is a B-85 that they tell me is gas. It also says Thermodyne on the hood, which I always thought was the open chamber, direct injection diesel. Anyone offer some clarification? I tried researching, but I have not found anything.

I tried researching, but I have not found anything.B model fire trucks were all odd numbered.Don't ask me why.The Thermodyne also reffered to the overhead valve Mack gas engines,the flatheads were Magnadynes. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/28446-b-model-designations/#findComment-147026 Share on other sites More sharing options...

mike69mackman Posted November 20, 2012 Share Posted November 20, 2012 Let me toss a question in the ring. I see b models with different designations even though most look the same. How do you tell the difference ? I know some of the cab designs changed a bit but is that it?

How do you tell the difference ? I know some of the cab designs changed a bit but is that it?Actually the cabs didn't have anything to do with the model,because most models had different cab options,sleeper,standard,concave,etc.The desiginations had to do with GVW rating,application& engine used.

Maddog13407 Posted November 21, 2012 Share Posted November 21, 2012 what engine was in a B405 and 505? jw. also while were talkin about it i notice my B475 never had any b models emblems on the hood but i believe Mack made a regular B47 model. wonder why they didnt put an emblem on the hood? they just fulled the two holes with small phillips screws.

Maddog13407 Posted November 21, 2012 Share Posted November 21, 2012 bet thats a rare breed of emblem to run across. this one looks to never had any emblems on the hood. also pics from the factory and in the Mack B model firetruck book show no hood emblems. kinda odd since Mack made up emblems for every other little thing , B422, B421, B615, etc. Quote Link to comment https://www.bigmacktrucks.com/topic/28446-b-model-designations/#findComment-147231 Share on other sites More sharing options...
