"Back to the OP, I've run inserts for tens of thousands of hard miles towing a camper) without trouble. As for inserts only being available in 0.010" increments, I agree, that is a big minus. Maybe vendors would be well advised to offer them in 0.005" increments."

I guess I would agree it would be nice to see sizing increments of .005" but the tooling to create another size in between the existing sizes may be costly. With the extra sizes each close size would only sell at about half the present rate. The cost of the present inserts would have to be more to cover these costs.

Having built over 150 of these engines with inserts, I think if two sizes could be added to the present mix of availability the most needed sizes would be: .025" and .035".
I find I use .020" and .030" sizes at a ratio of 2:1 over .010" and .040".

I just received an order from my supplier on main bearing inserts. The next time I talk to him, I will ask him if it would be economically feasible.

Good Day!
