PaceMetalFab Posted February 24, 2018 Share Posted February 24, 2018 I have a '93 RD690S and I am trying to determine what size axle I have on this truck. I have looked at the data plates inside the door jambs and there's nothing. The number on the front axle is 3QHF5448 . The VIN for this truck is 2M2P261C1PC014198 Is there a site that let you look up this build info for Mack trucks? Thanks everyone.

j hancock Posted February 25, 2018 Share Posted February 25, 2018 Do you have the FA number off the axle? I have some capacity info using the FA number. Like FAW537C 12,000 lbs, FAW18 18,000 lbs.

PaceMetalFab Posted February 25, 2018 Author Share Posted February 25, 2018 J Hancock, Let me look on the axle. The photo I attached is all I found. I may have overlooked another set of numbers. Quote Link to comment Share on other sites More sharing options...
terry Posted February 25, 2018 Share Posted February 25, 2018 That looks like maybe a 12,000 lb. axle, the 18 or 20,000 axle has kind of a s curve there. terry Quote Link to comment Share on other sites More sharing options...

Vladislav Posted March 4, 2018 Share Posted March 4, 2018 Check out the other side of the axle beam. There should be FA and so on. I'd expect seeing FA W538 14000lb on your truck but this could vary.
