An IP Setup Question
I have all the gears lined up on my '88 7.3 and I'm ready to put the IP on and I realise that I don't know if the IP has any internal timing built into it.
So my question is if the IP can be setup at 180° out?
I haven't seen anything on this list or in any of my manuals that would indicate orientation, but I really don't want to get the whole thing set up and then have that kind of problem to solve.
Thanks.

I Thought once all the gears are lined up then thats all the alingment you need. When you put the ip in (or at least I thought) it only goes in the gear 1 way where the notch in the shaft lines up with the gear, so I didn't think you could get it 180*. I guess you might be able to get it 120* or 240* off since it does have 3 screws if there is not a pilot notch. I know I have changed them before and had no trouble and never even thought about.

Yes, but the IP still has a 1/1 internal ratio. You can spin it around and just line up the dowel pin in the gear (if you are at #1 TDC). If you have taken the IP apart you can inadvertently be 180* out on the input shaft to head timing.

Im not following the issue. The only way to get it out of time is if the gear housing was taken off. Otherwise, just stick the pump in align it up an go. I have changed about 10 of these in the past coupple years, (only 2 or 3 being defective) and never encounted what you are describing or any problems as that goes. I didn't even pay attention when I changed it if that says anything cause I can barly remember what it exatly looks like. The only way it could be 180* out is if the gears were moved. It doesn't matter what position or degree the crank/cam is in when it is installed as long as the dowl pin is in the slot then your good to go.

I'm comfortable with the setup, I just wanted to be sure that I hadn't overlooked something. This thread answered all my questions.
Thanks.
