Crankshaft Thrust Surface Condition

[DeNoZZo]

I recently had my crank worked on. I had the rod journals cut .020, the mains/rods polished, and the soft ball plugs replaced with set screws.

I noticed the other day that there were some issues with the fillets on some of the rod journals. And also that there was still bearing material on the rod journal that suffered a spun rod bearing.

Today:I also noticed today while inspecting at the crank again that there is a small step (around .003) around the radius of the pressure side of the thrust surface about 1/8" from the journal. On the side where there is no pressure from the clutch, it is a clean surface. I believe I should take the crank back the the machinist and have the old bearing from the rod journal removed by acid, and the step I noticed today on the thrust bearing removed before I assemble. Any input?

If you had the crank worked on and that's how it came out, I'd take it back to the machinist and show him.

Yes I'll definately be taking it back to have that bearing material removed from the rod journal. But what really concerns me is that step on the thrust surface. If I have that removed I am afraid my crank endplay will be out of spec. Does anyone know how far the crank endplay can go before hitting the crank trigger sensor?

That crank is done. It has obvious heat damage and still has an irregular surface.

Just out of curiosity where do you see heat damage?
