I pulled the crankshaft sprocket off of my 1999 Legacy (2.5L). It was a bear of a job and required a lot of prying. At one point I got careless and had my prybar applying pressure directly to the back of one of the tabs on the rear side of the sprocket---it snapped off.
Here's a photo:
I assume these tabs are used by the proximity sensor to tell the computer the crankshaft's position. Therefore I assume I must replace the part. But before I order it, I wanted to verify with the experts here. Can I get away with not replacing it?
