KAMA with injector pump leak

[Paddy]

I have a KAMA 454, 45 hp with a 3 cylinder diesel. I have noticed where the lines come out of the top of the injector pump, they are leaking. It's not the nut where the line tightens but under the hex just below. see photo. With tractor off, you can see the leak by using the priming pump. When running it just drips. What is the sealing method that has failed?

It runs fine. And will want to address before it doesn't!

Its just an oring.. should be 2.. Behind the hand primer is the pump name plate.. get the #'s..
DONT SCRAPE IT.. get some gasket/paint remover in a spray can..
U see the "slots" under the nuts?? that's how u set the equal delivery for each cylinder..
IF u get THAT OFF, it'll skip alittle.. just mark it to the housing.

the pump guy,

Thanks. I put a black arrow showing where I see the leak. The red arrow is the slot that needs to be put back in the same place if moved?

Does it look like I can replace the O-rings without taking the bracket off? I might be able to pull the 3 lines off and then spin the nut below?

Oh OK..
Yes u can unscrew the black arrow w/ little consequences.
You'll find an oring on the "delivery valve" holder & a copper gasket under it.
Be careful when lifting the holder.. there is a spring & possibly a valve{volume reducer} in the spring..
I would tighten the 2 nuts down BEFORE I loosened the dv holder.. JUST TO MAKE SURE it didn't turn..
IF u have a torque wrench.. & you'll NEED ONE to put it back together.. TRY re-torquing the dv holder to 65 FT LBS before ripping it apart..
