Thanks for the advice, I was hoping you'd answer. I am contemplating using Loctite High Strength Sleve Retainer to take up the slack in the crankshaft keyway and/or main gear splines. The key fits snug in the cb gear but there is some play in the keyway as well as between the splines and main gear. The Loctite Sleve goo says it "restores fit to worn or out-of-tolerance assemblies". Also says you can disassemble part by heating to 500 degrees and use a puller to separate. Please stop me before I make a mess! Don't know what else to do if the new key looks the same as the other and fits sloppy in the keyway. thanks again rep p.s. The mangled lockwasher was only on one bent over.
