Another option might be a "Tach N Tune" It's like setting the timing on a gas burner. It has a crystal pick up on the #1 injection line that senses the injection pulse. You mark the dampner at TDC and use a timing light. An LCD display shows the degrees of advance. There are other names for it I can't think of right now, but it is comonly used on marine diesels that use Bosch or Stanadyne pumps. Also used to time John Deere engines and they have their own tool, but it does the same thing and can be used on any PLN engine.

If you have a Deere dealer or repair center near you they may be able to do it. It's a dead on accurate way of pump timing. International used them on the 6.9, 7.3 DT360, DT366, DTA366 engines. Their part number for the tool is ZTSE4141. One of their older dealers may still have one laying around too.
