The Cam locks are used in disassembly, assembly and final adjustment. The factory tools are pretty basic. Why Jake developed his is a good question, they may be superior in some manner to the factory tools.

Well, I can tell you the others, including some shops that have gotten themselves into trouble not using them, would not agree with your assessment. After you hear the same scenario for the third or fourth time, particularly from someone you know fairly well, you have to consider it as a potential fact. We have never encountered this issue in my shop, but my guys always use the cam locks, regardless of how many chains the engine carries.
