Outbehindthebarn Posted January 27, 2014 Share Posted January 27, 2014 I have been looking at buying an r model and was wondering about the steering box placement. Can anyone tell me why some have the box mounted at a quirky angle on the inner frame rail, and others have a more traditional looking box mounted on the outside of the frame rail?

doubleclutchinweasel Posted February 1, 2014 Share Posted February 1, 2014 I have been looking at buying an r model and was wondering about the steering box placement. Can anyone tell me why some have the box mounted at a quirky angle on the inner frame rail, and others have a more traditional looking box mounted on the outside of the frame rail?Well...I'll take a shot! I'm sure somebody will let me know if I'm out to lunch.The original R model came out in 1965, built on the same frame as the F models, which came out in 1962. Look at a cabover F model, & the steering box looks pretty normal.When Mack put the R & U models on that same frame, they just changed the steering tube & left everything else the same for commonality's sake.As far as the outside placement, I have no clue. Maybe a western Mack thing? Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Dirtymilkman Posted February 1, 2014 Share Posted February 1, 2014 20,000 lbs front axles have twin steering gear, one on each side. Lighter axles just have one. It all depends how the truck was spec'd Quote Link to comment https://www.bigmacktrucks.com/topic/34430-r-model-steering-boxes/#findComment-229795 Share on other sites More sharing options...
ducky698 Posted February 18, 2014 Share Posted February 18, 2014 Hi All, from what I have worked out the R series had spread rails at front requiring steering box to sit inside the rails, the mack westerns had straight rails requiring the box to be on the outside.Grant 2 Quote Link to comment https://www.bigmacktrucks.com/topic/34430-r-model-steering-boxes/#findComment-233273 Share on other sites More sharing options...
Maddog13407 Posted February 20, 2014 Share Posted February 20, 2014 I have seen R models with splayed frame rails with both straight shot steering shaft to box connections and have seen the one with weird quirky angle you are referring to, don't really know the reason.

doubleclutchinweasel Posted February 20, 2014 Share Posted February 20, 2014 Again, i'm pretty sure the odd-angle boxes are shared with F-models...Personally, I've never seen a straight one..not in person, anyway.
