I will soon change the timing chains and tensioners on my 2000 XKR and thought I could make the camshaft locking tools my self.
It would be nice if someone could tell me the dimensions.
I do have the special tools for the crank pulley, but do not want to spend the extra cash for the locking tool that I will use only one time.

 

I think on that engine you are just making sure the flats are in alignment so a straight edge can be used to check it once you have the chains on.

 

If you do make a tool make sure you make it from steel. Aftermarket tools made from ALU. will allow the cams to turn (reported many times) and the result is not satisfactory. Best of luck.
