What's to prevent oil from leaking from the back side of the hub through the bolt hole?

It's a precision taper fit, and damn tight, once the bolt is torqued to a mere 18 ft/lbs. The o-ring behind the hub seals the joint between the crank and the hub, the radial seal between the hub and the case. if your hub was loose, I'd REALLY carefully inspect the surfaces of both the crankshaft and the hub. use a bright light and magnification if necessary. Also look at the key and the keway in the crankshaft. Perfection is a must here, anything less can cause the hub and crank to separate during operation, and that's something you REALLY don't want to happen.

The Cap'n Yeah, make sure the hub is not damaged at all, because if it is, your wood drift key will never last. |
