DRESSER GALION A606 injection pump

This Dresser GALION a606 came with injection pump removed. The unit has been rebuilt and ready to install.
I am sure it was removed with no thought to timing or any other pre removal engine positioning. What am I going to need to do to install this injection pump properly so this machine runs again. What info do I need to provide? Can you point me in the direction to obtain the appropriate shop manual? Thank you in advance.
