I plan on doing the job as Sixto suggests without the basket. I will look at the removing the timing gear when I pull the vacuum pump. I think ya'll are right there is not enough slack in the timing chain.The FSM is incorrect on setting TDC for a 606.910. The FSM says to look for the pin punch mark on the 606.910 there is no pin punch mark. If one goes to FSM cam timing procedure you will see that it explains that there is a hole in the cam and the cam tower on the 606.910 to set TDC. The car has been sitting since July due to a family emergency and misc. other problems. I do not remember positively how I set TDC in July. I probably removed the #1 glow plug and felt for the piston and compression since the procedure was wrong and I did not look at the cam timing procedure. I set the timing when I checked it in December using the hole in the cam gear it is very easy to see the hole and set TDC visually. In neither case did I pull the cam cover.
I am really not sure what the index on the injection shaft set at I will check. Why can't you just take the link out of the timing chain and reattach the link?
