With a new impeller and liner most of the shims should be on the nut side to start with, all but about 1 or 2 usually. As the impeller and liner wear you move 1 or 2 to the top or inside of the impeller to move it closer to the liner to keep the tolerance correct. If I'm reading correctly you are starting with most of them on the wrong side.
No, I had three shim washers on top (bearing side) of impeller and the spares on the bottom (nut side) and it was contacting tge liner so I moved one from top so it gave the impeller more clearance. As the liner wears common sense tells me I will move more shim washers to the top of the impeller to maintain proper clearance.
I am just wondering why my shaft is moving so much and if it is normal. There is at least 1/16" play left to right but none up and down. This tells me there is no way I can get .030" tolerance with that much movement.
I guess what I'm saying is I must be overthinking this and I should just not shim my impeller at all and go from there. Sound about right?
