Big R Posted May 11, 2021 Author Share Posted May 11, 2021 Thanks for the quick reply. Is it possible it was original equipment on the truck? Is it something fairly easy to get parts for or has it been obsolete for some time?

mrsmackpaul Posted May 12, 2021 Share Posted May 12, 2021 I think they fitted these to some western Macks, dunno about parts but I feel they arent that common and certainly not in Australia Paul Quote Link to comment https://www.bigmacktrucks.com/topic/66681-rear-suspension-identification/#findComment-473747 Share on other sites More sharing options...
mrsmackpaul Posted May 12, 2021 Share Posted May 12, 2021 Looking at the second photo it looks like your chassis has been joined so I very much doubt thats original Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/66681-rear-suspension-identification/#findComment-473748 Share on other sites More sharing options...
Big R Posted May 12, 2021 Author Share Posted May 12, 2021 The frame is in really rough shape actually. Someone has run flat iron trying to stiffen it up, it is a single frame. I thought all the 61 were at least double but not sure. Maybe someone else knows.

topo Posted May 12, 2021 Share Posted May 12, 2021 looks like the same suspension used on a 43 White 666 I can't find any model numbers other then Timken in my books .

Big R Posted May 12, 2021 Author Share Posted May 12, 2021 Thanks for the replies gents! Not a very usable ratio (about 7.1) and the bushings are all shot. Probably cheaper to upgrade than to try to repair this setup.

mrsmackpaul Posted May 13, 2021 Share Posted May 13, 2021 I think its either 5.85 or 5.65 is lowest ratio for these Rockwell took over Timkens qxle division and continued to make these but as a 6 rod I have been told that the centers are interchangeable, I have two center's to replace the 10.22s in my Federal I'll find out when I try to change them if they are Paul Quote Link to comment https://www.bigmacktrucks.com/topic/66681-rear-suspension-identification/#findComment-473809 Share on other sites More sharing options...
Vladislav Posted May 21, 2021 Share Posted May 21, 2021 Definitely Timken bogie and judging by the color of the diffs it could have military origin. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/66681-rear-suspension-identification/#findComment-474155 Share on other sites More sharing options...
