HD wrist pin lock rings are used on the oem pistons in the panheads and shovelheads. The newer HD’s, and most of the aftermarket replacement pistons use the spiral-lock method of piston pin retainer.This is a HD spiral-lock installation tool, it is NOT a HD lock ring install tool, they are very different tools and function in very different methods. This is a very good tool for the spiral-lock installations, but it is mislabeled! Jims should know better then to label this tool a “wrist pin lock ring tool”, it is not.Here is a photo comparing this tool with a lock ring install tool:[…]
