woodruff keys

[eugene]

replaceing crank timing cog could some one tell me how to get the cag ontothe woodruff key
without the key sliding up the shaft and is it meant to be a very tight fit as this is
doing my head in 

[extreme90]

i use bearing fit to glue the keys onto the cranks
but usually
by holding the key as a slight angle down and a quick sharp tap with  a copper mallet on the gear sends them home

Grease or like he said, bearing fit, it won't do any harm at all.
