m5040 Posted February 7, 2008 Share Posted February 7, 2008 My R686ST was converted to a single axle dump, the numbers on the right rear axle tube (as best as I can make out) are FA49343P13 D23C. It has 6 whole/stud axle flanges. Can anyone shed light on its weight capacity? And what years it might have been made? It has stamped brake shoe tables if that matters.Thanks in advance for helping Quote Link to comment https://www.bigmacktrucks.com/topic/3392-rear-axle-weight-capacity-and-vintage-anyone-know/ Share on other sites More sharing options...

vanscottbuilders Posted February 8, 2008 Share Posted February 8, 2008 I think Thaddeus is correct at 23,000 lbs. and the stamped brake shoes make it fairly new.Probably post 1970.Send the info and a donation to the Mack Museum, and I'm sure they will confirm it.Paul Van Scott Quote Link to comment https://www.bigmacktrucks.com/topic/3392-rear-axle-weight-capacity-and-vintage-anyone-know/#findComment-16849 Share on other sites More sharing options...
