advancing timing

[jamesstcox]

I'm replacing my IP on my 7.3 Idi(the motor is out and its a bigger injection pump then stock) I'm wanting to advance my timing 10-12 degrees. I have no clue where to really start on doing this task any advice would definitely help.

Have you searched this forum at all? This topic has been covered dozens and dozens of times. Basically loosen the three nuts on the pump and turn it towards the passenger side. Best way is to get a timing meter.

Also, I don't know your experience level so hopefully no offense - never loosen the three nuts or try to change timing with the engine running...

I probably have 20 or so timing threads in my IDI timing Folder, here is one of them.

How to set the timing on your 6.9 or 7.3 IDI and how to buy timing equipment.

This thread is how to set timing on your NA or Turbo 6.9 or 7.3 F250 or F350 pick up. When should you check your timing? Every 30,000 miles. As your pump and injectors wear, they begin to open sooner generally. (Lower pop pressure.) This changes your engines timing. As an IP wears it may take...
