Sears / West Bend Lower Unit Gear

[KingsPoint]

I have a model 571.58301 West Bend air cooled, 1.25 single cylinder engine. I have it all taken apart and am restoring it (ie: cleaning and painting) piece by piece. When taking the driveshaft out, I accidently split the pinion gear (the one mounted on the engine shaft) in half. <br /><br />Anybody know a source for these? Is it a standard part? It's a beveled gear, with a tapered hole that holds it onto the shaft. It turns another beveled gear on the prop shaft.<br /><br />Thanks.
