    Summit K8600

    Thanks to this post and a few others regarding the Summit (or anybody's) cams, I did a little more cam inspection than usual. Anyhow my new K8600 looks good regarding lobe surface, oiling holes and front journal grove, etc. (FWIW: I believe Summit indicated to me that Crane grinds their cams.)

    One question though, at the edges of the lobe are sharp edges. (Not burrs, and not on the lobe surface, but rather on the side of the lobe at the 90 degree intersection of the ground surface and the cast lobe.) Should a guy carefully chamfer this?

    Sorry to answer so late, but this is important.

    Should not be necc. to chamf., but make sure the oiling holes are thare. It might be a good idea to run a pipe cleaner down the holes as well to make sure thare is no sand still in the cam.

    Thanks for the reply. Looking back it seems like kind of a dumb question, but I was being pretty anal when I assembled the motor, especially w/the cam due to some apparent issues others were having. Fortunately, I've never (knock on wood) had any cam issues in any of my motors.

    Does anyone take the time to thoroughly clean the cam, before lubing and installing?
    In America, there is no natural, moral, or legal right, to obligate another person or persons, to your dept or desires.

    Define "thoroughly clean" . . . shooting brake cleaner though the oiling holes and washing the outside down count

    I always run mine thru the solvent tank, rinse thoroughly, and blow dry with compressed air before applying the assembly lube. I do the same with cranks and rods. Engine blocks get hit with soap/water and pressure washer, all passages cleaned with brushes. Everything always has to be clean.
