i hvae some of them and they will self clearance which is not good, so deburr ahead of installation. it's not hard to do or time consuming.

Yes I see what you mean. Of cause there will be metal dust in oil, if they don´t move smoothly, witch they like you say apparently don´t do.
Is a fine paper enough, or may be a hand tool is faster and more efficient?
Thank You for you advice.
