Maddog13407 Posted October 5, 2016 Share Posted October 5, 2016 tryin to figure out why a B61 would have a 7.49, that would make it go about 35 mph. 7.49 is a gas job ratio commonly found in B42's Quote Link to comment Share on other sites More sharing options...

steve s. Posted October 5, 2016 Author Share Posted October 5, 2016 The rears are out of a concrete mixer truck. With 22" tires and a double overdrive 7220 quad box, it would run about 52 mph. This was a very common ratio for mixers and dump trucks. Quote Link to comment Share on other sites More sharing options...

Might be interested knowing exact number of teeth in the upper gear set(s) Although for the best I'm looking for something faster. Nearly 6.5. Already looking for a while though.

steve s. Posted October 18, 2016 Author Share Posted October 18, 2016 Vlad, I don't have any way of knowing what the upper set of gears are without taking it apart. The Mack TS 442 manual has that information for front mounted single axle carriers, but it does not list that information for top loaded tandem carriers. Maybe someone else has better information.

Steve Steve, I suppose it's not too easy to find a chat on B-model's carriers with teeth counts on every gear setup. Seems to me much easier to remove the big side cover on the carrier. It allows to cont both bevel wheel and pinion. In my case I have 9.02's and will have to use my original lower sets due to the design. So the upper ones is the only game to play. In very theory your lower sets might be slower than mines. If so I would achive something faster than 7.49 you have now and it seems good. Although IF you will be so eager to spend time removing the covers and count teeth, and IF the cound is good, I will want you to take the diffs apart and send me the gear sets only. So I'm afraid I'm too cantankerous buyer in this case Vlad Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...
