Thing is, you may as well get the timing cover off and do your belt as well.

I had this last year, the outermost key had snapped and taken a chunk of the shaft with it. I managed to repair the crank with liquid metal and replaced both keys and the timing belt.

I take it you have the 300TDi engine (2xkeys?) The inner one drives the timing belt sprocket and the outer one the crankshaft damper. There's a lot of vibration when this sort of thing happens, so I suggest you strip it right out - if only for peace of mind. The 200TDi engine has one key and if you can get all the bits out, then you could just slot a new one in without taking it all apart.
As Dan says - you were lucky if it hasn't re-shaped the end of the crank nose.

yes but only half of the woodruff key drives the crank damper  :wink:
and thats the problem in the first place
expecialy if you have air con fitted  :roll:
everytime i do my timing belt when the pully is removed i always apply abit of locktight to help hold it into place
ive already had one wrecked crank, i dont want another  :evil:
