[QUOTE="ossagp, post: 197648, member: 1650"] If you had the cases apart and then back together you usually get a certain amount of bind when the crankshaft goes back into the main bearings. The simple fix right now is to take a plastic mallet and smack either or both ends of the crank shaft at about a 45 degree angle. Widely used method for relieving the stress by engine builders who squeeze them together. If you want to learn a gentler method of assembly I have that too, but guys that build them for a living using the presses end up having to do that frequently. it also happens when they just go together cold by hand sometimes. So give that a try before you tear down again. Since you have about a 50/50 chance it will still slobber after you get it running, check back for the fix for that too. [/QUOTE]
