I did not know there were (2) different FDT hydraulic lift pump drive pulleys. All the IPLs, 990339 square tank, 990367 & 990468 round tanks, I have only show P/N, 157231. Unless, the wider pulley was installed on the 12HP models from the factory and is P/N 157484.

The parts manual for the B110 shows different part numbers for the 10 hp engine and 12 hp engine for the pulley.  The 12 hp is 1.00 thick.  Is the thickness the only difference?

Yes. The 10HP is 1/2" thick and the 12HP is 1" thick. I used 1/2" long driveshaft spacers to space the pulley away for the flywheel when installing a 16HP. I think the 1/2" pulley is Simplicity P/N 157231. Is the 1" pulley P/N 157484?
