Santerre, yes, the six bolt rims with the spokes. In the case of this Howe pumper, the trans has normal band brake drum on the back .
A short driveshaft to the transfer case drives the pump, which disengages the rear end at the same time , as you say.
This results in the odometer clocking miles while pumping, so there are actually a lot less than the indicated 5620 miles showing!
I would think this truck, if sold for over the road use, would have had a two speed rear end pretty much standard equipment?
