fingers crossed! Im grasping at any glimmer of hope ...
Divenut; I think this is what im looking at too. RRR; I failed to trust my old gauge.
I think I get where you are going, but im having a hard time figuring out how to precisely measure that distance. Let me ask you this? Are the two radii (cam gear and shaft gear) supposed to meet exactly at their widest points? Mine was more difficult to remove this time. It was slightly below the apex of the cam gear radius. My priming tool extends down 11 11/16" from the top of the block down into the pump.
