[SEL] Babbitt Lapping Compound

[jbcast at charter.net]

I use the yellow time saver, medium grit. It will dull the shaft but does not cut the steel. I tried the green one time and it cut the steel. After use I clean everything and polish the shaft. We use this on antique two cycle marine engines where crankcase seal is accomplished by bearng fit, no seals, and it's critical to have a good fit. These engines are run in boats under load with no problems.
