jakebrake86 Posted December 28, 2012 Author Share Posted December 28, 2012 My 8ll is going to need a rebuild soon... How would a 5 and a 4 hold up in a tri axle dump truck? I've heard they don't handle torque very well, but then again people ran them for years.

Maddog13407 Posted December 28, 2012 Share Posted December 28, 2012 thats a straight 5 with a 4 speed auxillary. a 5 and 4 quadbox would never stand that torque. those are the shiniest ''All Steel'' wheels i have ever seen on the front axle also haha Quote Link to comment https://www.bigmacktrucks.com/topic/29049-96-rd-with-a-5x4-yes-please/#findComment-153629 Share on other sites More sharing options...

Would it hold up? I'm thinking the aux would go in place of the swing bearing.

Green Dash Posted December 28, 2012 Share Posted December 28, 2012 One of the operators manuals in the BMT Wiki section shows the option of a Spicer 4 speed to go behind the 1076/1078 transmissions. I think it was the R & U manual. Quote Jim Link to comment https://www.bigmacktrucks.com/topic/29049-96-rd-with-a-5x4-yes-please/#findComment-153666 Share on other sites More sharing options...
burnin oil Posted December 28, 2012 Share Posted December 28, 2012 The biggest Spicer aux box I am aware of was rated at 1250 ftlbs of torque. Big sucker with twin counter shafts. You see them for sale occasionally on ebay. They seem to be mostly used by oil field trucks. Being from Houston I bet that was the case.

terry Posted December 29, 2012 Share Posted December 29, 2012 I have seen a steel fendered RD with a mack 5 speed and a 4 spd twin countershaft aux. behind it, also think it was an ex oilfield truck.

Coalbucket Posted December 29, 2012 Share Posted December 29, 2012 (edited) Look at that winch on picture number 12. Yes this was an oilfield truck and yes it's a 5-speed MaxiTorque with a Spicer 4-Speed auxilliary. The 4-speed is in there primarily for the "Power Tower", a top mounted PTO on the Spicer 4-spd behind the rear window that can run full horsepower. Specs I've seen, they are rated at input torque of 10,000 lb-ft, not very much when you look at peak engine torque times transmission ratio of the main box. But if you are careful with it you won't hurt it.
