Problem with Zero TDC Flywheel. Help Please!!

[viseven]

Hello all.
I knew this forum some time ago as I have a Volvo 745 D24T with +710.000km's and run very well, but now i have a problem.

A few days ago i started my car and the engine feel unstable, smoky black, got worse until the engine stalled.
The pulley of injection pump is skidded (surprisingly, not have cotter pin in the keyway) and the motor is stopped by this problem.
When I put the pump back to her point, I checked the distribution timing was correct, and saw that it was not correct.

My d24t has two marks on the flywheel, a line and a zero ( http://i49.tinypic.com/19pefo.jpg ) . I removed the first injector and used a very thin steel wire to feel the T.D.C., which coincided WITH THE LINE on the flywheel.
However, in the Greenbook there is no mention of this line, and makes reference of the zero "0" as T.D.C., which is a few degrees AFTER T.D.C. Any body out there who could tell me which mark to pay attention to? I'm worried of mistiming the camshaft and ending up scrapping the motor.


Thank you very much for your attention and dedication.

Jorge.
