I picked up a scrap P7100 a while back and just got around to destroying it to see how it all worked. One side done, need to flip it over and do the rack side, then widdle it a little more to see everything better, then work on the governor portion. I don't want it to be apart enough for it to not operate, as in parts falling out.. There is a cut away view of a P7100 floating around that everyone has seen but I want to see how it works as in operation. I will make a video of it all and show how everything works together. The pump side is pretty straight forward, it's the governor side I really want to see in operation. The theory of the governor is simplistic as well but if you look inside at the governor on these pumps you don't exactly see anything simplistic. Kinda like saying an engine works by injecting fuel and igniting it, yet pop the hood of a new car and explain where the simplicity takes place and what everything else is for.. Without further delay, here's what I got so far.

Right on... Thank you for your time and effort in done these pictures...

I can't believe how some parts of the thing are completely unheard of concerning pics. I have searched for rack and come up with absolutely nothing, which is why everyone thinks it's a gear, it's not. I searched for plunger and all you will ever find is the barrel. The entire thing above the cam comes out (all of that is considered the plunger assembly I assume), this is the reason for the 6 holes on the bottom of the pump. You take the cam out then you can pull the plunger assembly out, though it might be a little more involved than that. The rack will tie into it on the other side. I did find some good cutaway pics while searching around. Nothing of the rack of course.. But they all fall short because a picture does not show operation. The good thing is that the governor doesn't seem to be implemented into the housing very much so I an cut away everything and see every part of it in operation.

If I ever get lucky and find a VP44 core I can rip apart I would do the very same thing but its so rare to just find one laying around... But once again for bring this information to the site so others may learn...I know your going to be building a article of this right?

I thought I always read that people had junk vp's laying around. I was gonna ride today but I am not going to try and ride soaking wet in 40f weather lol. Which means I'm gonna spend all day cutting this thing apart. Maybe ill post some vids of what I'm doing throughout the day.

Update to this. Here is a video I made. I have it on another forum too and that's why I said what I did, I know you guys are used to me doing all this crap

I had to go up and rate the thread excellent... Wow! You did a awesome job cutting that pump open to see the guts... More! I want to see more videos...

I did find something else to help me with disassembly. http://www.competitiondiesel.com/forums/showthread.php?t=80597
