Default Re: Help.. Broken Bottom engine casing.

The woodruff key should fit fairly snug in the groove (keyway) provided in the crankshaft. If it doesn't you might consider replacing it. If the keyway is worn then we have a more serious problem. I'm sure someone is going to suggest JB Weld for this fix too but as I said before, I'm not a JB user. There are epoxy based products with much more strength that I would use to hold the key tight. Devcon makes an industrial metal repair material, Liquid Steel, that would assure the key would stay. Let's determine first how well the key fits the keyways in the crankshaft and gear. If you find the fit good, no slop, you can try a small dab of superglue to hold it in place while you install the gear. If the key rattles around in the grooves get back to us for more detailed help.
