Your comment about lateral wear caused me some concern so I researched the subject and found an IPB and sectional view of my pump. Nowhere in the unit is a discrete bearing per se. Apparently the cast iron casting is the race for the geared shaft.
The PDF indicated that misalignment of the shaft could cause premature seal wear. I consider V belt drive equivalent to misalignment. The sales info states that the pump is made to be mounted directly to the engine with suitable couplings to keep any pressure off the input shaft other than radial drive pressure.
However, there is no time line on the the "premature wear" comment. I don't see this thing getting 50 hours of useage in it's life time. Considering the alternatives and all I think I will go ahead and pursue the original plan.
If that fails then Plan B is in effect which means I will use the engine out of the old mower. I will build a bracket to mount the engine in it's normal vertical shaft position and mount the pump under it. Not room to do that with the engine in the mower frame. This I will just slide in my little trailer and bolt her down with battery when splitting time is here. I'll add a hitch to the rear of the trailer and just tow the splitter/cylinder section behind the trailer and tow it all with a ZT lawnmower to the splitting site.
