Farmall H Water Pump Spacer

I am rebuilding the water pump on my Farmall H. I pressed in new bearings and seals. After I press on the pulleys and tighten the bearing retaining nut completely, the pulleys don't turn easily. I did add a new felt seal and there is some drag, but i believe it is more than is desired. The spacer that goes between the bearings may be worn, so when I tighen the bearing nut, I may be preloading the bearings.I don't know what the dimension of the spacer is to be. Does anyone have this dimension? I can't seem to locate a new one to purchase to I would like to machine a new part if needed.
 
Take the felt out and reassemble to see if it gets tighter as you tighten the nut. You can easily tell if it turns harder then. I doubt the spacer is the problem, those felts cause a lot of drag until they run a little while. Then put felt back in.
