Check IP Timing:


Timing the IP:
Edit: to advance timing, the top of the injection pump is rotated away from the engine, i.e. CCW looking at the IP from in front of the engine (end edit)

Some hints that I pulled from my thread on IH8MUD....Credit to longbow and doug720.

To remove if its in the truck:
- Do not need to drain oil from engine
- Used long extension with a universal to the inside IP bolts
- "I had to twist the pump out and back in from the gear sets which makes it easy to get a tooth off on reinstall." - Doug
- "Open up the little timing window cover and rotate the engine until the timing mark is dead on the pointer and then remove the pump. Try and make a witness paint mark or something on the IP drive gear location after you remove it so you can put it in the same spot when you re-install the IP so that it will be back to dead on the pointer when it is bolted back up." - longbow
- Remove the rear bracket off the IP to make re-install easier and then put the mount back on once it was positioned correctly and bolted up front.
- "Getting the pump out is tricky and takes some jockeying around to get it out of there." - longbow
