Response to The permatex is used...
Reserve that for the last ditch effort to save any given part.
If you look at a pin and bushing like its a 2 piece bearing then figure out which one you would like to wear-out
On the pump I would say no wear on either part.
Then you would go with equal quality steel with the same hardness.
Take 2 drill rods of the same material quality one bigger then the othe drill the large rod so the smaller one fits on the inside then harden both parts to the same hardness and you will have what you need.
Others will take an oil impregnated bronze rod make a bushing then use a steel rod and use it for the bearing.
With the amount of pressure exerted on the pin and bushing I would go with steel making sure the pin had the harder surface this would simplify disassembly for repair.
For a simple set up go with grade eight qualities.
Start with medium carbon alloy steel, drill and cut to size then harden it.
