I had to share the sprocket, the correct one is on the right.
I’m pretty sure the one on the left was modified because someone had built a pump with the cam plate 180 off., now I’m unsure if my leaking pump that I pulled is 180 off or not. I’m assuming it is as I usually keep the sprocket with the pump when I remove them from the engine.
If you look closely you can see the factory notch has a chip in it and the 180 notch looks factory, but it’s actually cut deeper now that you compare a factory sprocket with it side by side. Crazy! I don’t know how many needless hours I spent tracking non-issues because of that sprocket!
