opinions on this damaged camshaft

[st220kyle]

Inlet cam was damaged today due to the person changing my cambelt not using the locking tool for what it was intended for.
Pics to follow, but opinions on whether this is ok as is or whether it needs to be replaced?
Thanks

There is no locking tool for the camshaft only a timing tool. If you use the timing tool as a locking tool you will break off the end of the camshaft. You should use the timing tool to get the camshafts in the right place and the use a big spanner (22 or24 mm) to hold the cams whilst you tighten up the camshaft sprocket bolts.

Hi Barry

This should explain my question on another thread about swapping/replacing a camshaft!

As long as there is enough profile left for ful insertion of timing tool, providing the position notches are not affected in any way and all of the material that broke off is removed, it should be fine as this is not functionl part of camshaft in any other way bar for the timing procedure

You just use a spanner but...no idea if oil can attack that open metal seeing as its got no surface.
Ensure no small bits of metal are in the head at all.
