  1. I've been finding a lot of stuff across the web lately but geeeeez its a pain to find it all. I'm compiling everything I have found into this thread. What I have found is really good info and tells just about everything about the p7100. This concerns specs/teardown diagrams/all kinds of stuff. Clicking on these "[source]" takes you to where I found it. I don't like stealing people's info without giving them credit. Pump Specs There are 2 number plates on the P7100, one is underneath the throttle plate on the drivers side of the pump so you have to take the 3-10mm screws out and take that plate off to see it. That number plate concerns the front half of the pump. The other plate is on the very back of the pump and dictates governor characteristics. The numbers on the back of the pump will be something like RQV400...1150PA1172K Which decodes to: R = Governor Q = Transverse spring V = Variable speed governor 400 = Rated minimum speed (idling speed = 1/2 engine speed, engine idle 800RPM) ... = controlled range 1150 = Rated maximum speed (= 1/2 engine speed, engine max speed = 2300RPM) P = P series pump designation A = Modification letter 117 = Type code 2 = Suffix K = Torque matching by characteristic. [source] The numbers on the side of the pump (under the plate) will look like this: PES6P110A120RS7213 0 402 736 906 96628 08721 The first one can be decoded like this: PES6P -Denotes number of cylinders and Basic Pump Model 110 -Denotes Barrel & Plunger Size in MM A120RS -Denotes Cam rotation direction (Cummins is Right) 7213 -Denotes Pump series (2000, 3000, 7000, etc) [source] The next line of numbers seem to be a cummins lookup thing, but this website has put together a list of them, among other things. http://www.chathamfuel.on.ca/generic.asp?pg=appl_59&ti=Applications - Cummins 5.9 Here is that chart in a little easier to read format. Timing Lift values are found here. Timing Lift values expanded version. Injector Size Specs. Delivery Valve Flow Specs. Diagrams/Pics Big article on how the P7100 works (PDF) P7100 Dissected [source] [source] [source] Delivery Valve Dissected Injector Material Injector Dissected That should do it for specs and diagrams. More stuff to come another day..
  2. I finally got around to doing this, well not really I just threw it all together so it is kinda repetitive and you'll just have to excuse my horrible skills at showing people how stuff works. BUT, this shows a crapload more than you'll ever see anywhere else and I should probably be getting paid for it but oh well. Without further delay, heres 25 minutes of explaining. Everything else has already been explained in a write up: [*]Fuel Plate [*]Fuel Shutoff Solenoid [*]Smoke Screw [*]AFC (Starwheel) http-~~-//www.youtube.com/watch?v=Z3S65hqFaUo Some things to note that I forgot to mention: This is a 215HP pump, as you can tell from the retarding notches. The notches are on the very top of the plunger, you can see a slight recess up there, all other pumps are completely flat on top. It retards the timing because the spill port is left uncovered for just a bit longer since it travels into the notch rather than being covered by the plunger and allowing fuel to compress, this delay means injection happens later, retarding the timing. It is 4* delayed at the most recessed part of that notch. Another thing is that the oil inlet is TINY, it restricts the flow of oil into the pump so that it has a constant slow oil feed. It drains out the front very slowly. Any more questions? Feel free to ask.
