i was goin to change the tioming belt today on my 94 wrx and wheni took off the cover i noticed that that srocket on the crankshaft was off centre so took it off and the woodruff key has wore the crakshaft a small bit,, when i put on the new sprocket i could rattle it a little bit with a new woodruff key,, is there any thing i could to to make it solid i was thinking of putting a few small spot welds around it and ideas appreciated

 

e metal maybe ? weld would heat it up and prob destroy crank seal , which then in turn if woodruff key is welded in place crank seal will not go over it ...

 

or one i did ages ago was real bad so i thread locked the sprocket on too .. but would be real hard to get off next time

 

i was thinking of puttting a few spots of weld around the crank sprocket would it hold,,, did the tread lock hold

 

yeah thread lock goes solid mate with the heat , try to leave it a while to cure though..

 

think crank and sprocket will be different typres of metal and would not weld very well ..

 

cheers mate got liquid metal today gonna try get the woodruff key right with that and then threadlock the sprocket onto the crank triedto get some today but they had no strong stuff just medium strength
