Hone grit
Having a convo with another person as they were asking about dingleberry hone grit. He said someone told him to use an 800 grit ball hone. Seemed to fine to me. I would normally use a 400 on our bracket motors. What's yalls opinion on the 800? Assume moly or latest tech total seal rings

Re: Hone grit

Re: Hone grit
You'd panic then when the tech guys at Total Seal suggested finishing with 1000 grit levigated aluminum, counterclockwise for five strokes.

Re: Hone grit
Alan, if that's what they recommend then I would do 1000. I have been taught if it's too slick the rings wont seal. 400 works great on a bracket motor with no risk of a ring not sealing. I've never used anything finer but I know on a stocker motor that a ring combo can make or break you. That's why I asked.

Re: Hone grit
Like Alan said, call Total Seal and speak to Keith.
Piston ring material and technology has changed drastically. We are no longer in the era of breaking-in Chrome rings. |

This is what I've seen with my Mitutoyo SJ-210 profilometer after doing 20-ish strokes in clockwise direction, and 5-ish strokes counter-clockwise, with 400 grit silicon carbide hone, on Darton sleeves. In other words, excellent results. Mileage may vary. |
