aceshooter Posted July 17, 2013 Share Posted July 17, 2013 I need to know if Mack ever made a ten wheel dump truck with all wheel drive (6x6) with a maxidyne engine? In the 70's or 80's. and what is the model #? Quote Link to comment Share on other sites More sharing options...

j hancock Posted July 18, 2013 Share Posted July 18, 2013 Like I said, a DM6856 is a Maxidyne powered DM with six wheel drive.DMM could be six or eight wheel drive.Jim Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

jeffmackb Posted July 19, 2013 Share Posted July 19, 2013 Yes, they built quiet a few 6x6. The Australian Defence Force had Mack Trucks Australia build them about 940 RM-6866RS trucks starting in about 1983.These trucks were Six Wheelers, the four rear wheels were dual wheels.

jeffmackb Posted July 20, 2013 Share Posted July 20, 2013 The second 'M' in 'DMM' designates a setback front axle arrangement.In 'RM' and 'FM' it is the setback front axle. But not in 'DM', because a 'DM', is a 'DM'. It needs a second 'M' to designate the setback front axle arrangement.You can have an 'RM' that is only a 6x4 or a 4x2 e.g. RM-685RS or an RM-685RTAs Jim has pointed out, It is the fourth number that designates all wheel drive e.g. RM-6856RS would be a 6x6, RM-6854RT would be a 4x4. 1 Quote Link to comment Share on other sites More sharing options...
