well before rattle snake season gets into full swing I guess I had better go get this thing. besides the battery box cover the other thing I saw was missing was the bull dog, oh well I guess trucks 5 miles from home wont always be perfect !

A friend of mine has a Mack A-54 trans in his is a Du-plex. I cannot remember engine size. Is your trans one box or 2 (divorced) ? If split boxes it could have a 3 way auxiliary.Tin looks good on yours.Pretty sure A-54 was the heaviest gas job. A-55 was biggest diesel powered either 672 Mack or Cummins 672.Good luck. Joe D.

Joe: the aux is divorced and either a 3 or 4 speed aux.

Mike: how many A54 do you have, and do you have a battery compartment cover that can be copied? and yes its a big gas pot all I found was a thermodyne tag on the valve cover. mustta been a fuel hog it looks like it had 3 tanks 2 saddle mount 1 cab

I would think the aux. trans is a 3 speed not a 4 speed unless changed by previous owner. I had a spec sheet for a Mack A-51 and it was offered with a du-plex,mono shift or 5X3 main and 3 speed Brown Lipe or Spicer aux. This is not saying other trans. were not avaible just spec. sheet I had. There was a man in Penna. that had some A-Model parts I do not know if he still deals with it. His name is John Chalmers. It looks to me as A-Model Macks are getting some interest after all these years. From your picture the tin looks great after sitting out all those years.In Pa. it would have quite a bit of rust and bullet holes from target practice.Good Luck on the save. Joe D.

Mike: might have to take you up on the batt. cover will get in touch once I get this thing home, might have to add to the shopping list. Just thinking about other old trucks and don't ever remember other single screw trucks with a factory double frame. was this a common mack thing? Mike also do you know the starting serial number was for the A series or were they by year ? this one is 1620 and does the S stand single axle ? again thanks for all the help guys!!!!

S is for tandem. SX is for heavy tandem. X usually meant single axle double frame. could have started out as a tandem and someone made a single out of it. A models are one of my favorites and like others said seem to be gaining interest.
