Last winter I replaced the bearings and seals on my Harley rake. After about 40 hours of use this season it is pouring gear oil out of the bottom of of the chain box between the roller and chain box. Is there a secret to keeping the chain box sealed up other that the stock parts (o ring)? Other than this issue it works as it should. To my way of thinking it would be a great place for an HTD belt drive.View attachment Harley Rake.pdf
