John:
Splitters were used on Power Wagon having dual stubs PTO's to run two PTO sized shafts in the same direction, such as forward: one to a winch and another to a splined output drive for a post hole digger, for example. They were also used to run a frame mounted winch just behind the cab on some old telephone trucks. The driver could raise and lower a fromt boom via cable from the rear winch traveling on a pulley over the headache rack to the boom. The PTO front shaft to the winch could be left engaged in one directon while the rear extension of the same transmission-mounted PTO shaft could be run in two directions thru the splitter box, to wind or unwind the rear winch. A second PTO stub shaft came out the rear of the splitter box to operate the belt pulley or 6B spline drive at the very rear of the old PW.
The rear MU-3 winch on my W300 is bolted to 2" X 2-1/2" angle irons that in turn bolt to the bottom inside of the frame rails. I installed square "beveled washers" (not the correct name, but they are tapered washers, shaped like thin wedges) between the slopped inside bottom of the frame rail and the angle iron. The amount or anggle of the "bevel" on the washers should match the slope at the top inside frame rail, so when the washers was placed on the frame rail the results as a level (flat) surface on which to mount the bottom of the angle irons. These bevel washers provide a "professional" touch to the installation. Your large regional nuts and bolt distributor should have these in stock.
The sides of the drum on my rear MU-3 are about one inch higher than the top of the frame rails, buy my utility bed sits higher than that so I have plenty of clearance. Yours should work back there too, especially with a dump box that sits high off the frame rails. Good luck!
