Model T Ford Forum: Forum 2012: Piston Pin bolt notch

The bolt groove in the 4 piston pins that I used today was not ground deep enough. Has anyone had this problem? China pistons, bought about a year ago. Ended up grinding the notch .014 deeper.

If the grooves aren't deep enough, there may be other problems. Check carefully. A book like Audels has a lot of info on pistons. Be sure they're reinforced pins. If not, they may distort from clamping, and overheat the pistons. I know.
