I have a slight oil leak from behind the front sprocket on the freshly built SH2 engine. I need to investigate a little more but assuming the front sprocket nut is still tight the next likely candidate is the output shaft oil seal. If it is can it be replaced with the engine still built and in the frame?

My thinking is to remove the front sprocket, the oil seal retainer plate, the sprocket spacer, and then leaver the seal out. Replace the seal with a little oil to lube, replace the o-ring in the sprocket spacer, stick the retainer plate back on, and finally the sprocket.

How does that sound?
