Simplicity 9518 rebuild

[Johndeere3720]

while i was working on my tractor today, i found that i had 2 extra parts that arent for my tractor. These must have accidentally been put into my parts bag when i picked the tractor up from NewHolland. One looks like a fuel pump/filter of some sort (i may be wrong) and the other looks like some sort of pressure reliefe valve for oil??? anyone have any ideas?

well, here is my old pump. i put the red caps from the new one on the old one to keep dirt from getting in. Two of the bottom rollers are sunk in and one isnt. Would this pump be fixable? and not be to expensive? I have never taken one apart, would it be dificult to do if i did? the guys at NewHolland said that all the seals are shot in it. I wonder if they are still available yet this pump is about 30 years old so i dont really know for sure.

well, I just applied the silicone gasket maker to the mounting hole for the fuel injector pump. This should help with the air leak that i was having yesterday. I only tightend the bolts finger tight (to allow the silicone to set for an hour before tightening all the way). I hooked the kill switch back up and put some silicone gasket on the side access panel for a better seal even though it wasnt originally leaking.

well, i hooked the pump back up again. :confused2: tried cranking it, even sprayed a little eithur in the air intake but is just wouldnt fire. Checked the glow plugs, theyre fine. so you probably know what this means, time to take it back apart again.

well, i yet again have taken it apart, wondering why the pump isnt pumping enough fuel to start er' up. I checked out the cam and it is fine. rotates like it should, isnt wore out. So i brough the new used pump to NewHolland and a mechanic checked on it. he took it apart and said it was in fine mechanical condition but since it isnt pumping at 4000 PSI, i should send it back. So i called Roberts Tractor and i will be sending back this pump and will be getting another one off an Allis Chalmers 5015. The mechanic at NewHolland said that the pump appeared to be rebuilt. So i guess my tractor will have to wait yet another week-2 weeks until it will start. You can see in the first picture, it is very dificult to put it together and take it all apart.

You (and others) may be interested in knowing that the same pump is used on Massey Ferguson compact tractors model 1020 (and possibly 1010, 1030 etc.) which all use Toyosha diesel three cylinder engines.
My pump says Diesel KiKi Made in Japan and the other numbers may be misread either on your or my pump: I read NP-PFR3KD55/TNPT.
It also says (license BOSCH)

well, for a short amount of time, i got pump #2 from Roberts. This one was actually worse than the first corrosion wise. It too was a Diesel Kiki pump. I tried it out, and brought it to my mechanic at newHolland who advised me to send it back. But he did know a source that had a brand new one for $650. So as you may guess, i ordered pump #3.
