Apart from the monster steering gearbox it doesn't look any different from my DM686. What are the axle ratings on a dm800?

I have sent a info request to the Mack museum back in February but haven't heard back looks like the steer is at least 20k and the drivers are at least 55k 9:10 ratio

18K front axle w/old style grease-lubricated wheel bearings. 23K front would have 12 lugs.

55K bogie. Should be a stamped # on the axle 'bowl' SWS 68C or SWS-681C (C if s-cam brakes; W if wedge brakes). 65K bogie would be SWS-592C(W) & would have fewer but thicker spring leaves.
