My pump is leaking between the end housing that the injector lines come out of and the main pump body. Doesn't appear to be that difficult.
Posted a pic of where I'm at but nervous about what the next step is. The housing moves a little but won't come out. Looks like I need to replace the #44 oring in the diagram. Appears that those two shafts need to come out to get the housing off. Any tips.

Was lacking a bunch of info.

It's a 1979 ih574.
Pump is a va4.
Runs great but is leaking more fuel than I'm comfortable with.
 
I just went through one last month, my advise? Don't have a patch job done on that pump! Have it completely resealed, other seals are going to leak soon after if it's not completely done. Also, be aware if ANY parts are damaged by untrained hands, good luck finding parts. That's NOT a pump for the novice to handle. The stop and throttle levers have very fine splines, and need to be verified they are back on correctly on a test stand after re-assembly. That pump is hydraulically governed too, no flyweight assembly like the Bosch VE pump that replaced it. If you have more questions E-mail is [email protected]
 
"doesn't appear to be that difficult".. Famous last words of a fella getting ready to mess up bad..
Its VERY difficult.!!
It needs to go to the fuel shop..
Those 2 shafts have tiny springs & shims, that if lost, are almost impossible to buy.
& like DT said, the levers & shafts are splined & can go on 8 different ways..
Do yourself a HUGE FAVOR & STOP..
That 3.00 oring will end up costing you 3 Thousand dollars.. either for a pump or an engine.
Good luck with whatever you decide to do.. TPG
 
Thanks for all the tips everyone. I stopped where I was and put it back together today and it ran just the same but leaked worse. I'm sending to a shop not far from me to have it built.
