I got my stuff back from the machine shop & put the crank in the block. My machinist camfered the bearings for me, but not the thrust bearings. Looks like the thrust needs to be chamfered also? Anyone run into this? Anyone have camfered bearing in stock? I blued the thrust to see where it's has to be chamfered. This is on the edges of the main journals,not the thrust sides. Thanks Charlie
 
Usually the bearings come chamfered but not enough for the rolled fillet radius. I would be hesitant about chamfering the thrust.

Post a pic of the thrust bearing where you "blued" it. Maybe there is problem with the China crank with workmanship :rolleyes: . Where did you buy the crank from?
