I have a friend and he tore into the fuel pump on a F2400

[Butch]

I have a friend that is a maintenance man at a local Catholic school. What he asked me is light years above my pay grade regarding the school's F2400. Bottom line the engine was leaking fuel and he determined it was from the injector pump. He tore into it and now he has parts that came off/out of the pump that he has no idea where they came from and therefore no idea how it all goes back together.
Now with that being said and all that I have assimilated through osmosis from you all... I think he's in a world of hurt.
Is there a diagram that shows the "innards' of that particular injector pump?
He seems to think everything is like plug and play... easy peasy.
Any suggestions, comments or diagrams that I may point him towards? Thanks in advance!

curious, looked online ,Canada,eh.... pump is $2000 Cdn (NO internal parts....)

Sure pump repair is 'easy', IF you have the proper tools, IF you have the correct parts and YOU have the skillset to work on them.

Heck, there's fewer parts in the pump than an HST unit or a gear tranny BUT can HE fix it ?? Roll of the dice.

Big problem is WHERE was it 'leaking fuel' ? Sure hope it wasn't a simple gasket on the feed line..as no need to turn it into a 'science project' !

I'm sure others will reply...odds are option 'A', ''order new pump' or option 'B','take to specialized repair shop'

It does sound like he’s in over his head. Have him send it to a good pump repair shop.

I looked at Kubota illustrated parts list and Messicks and nothing showing for internal parts of the injection pump. All that was shown is below

But WOW I don’t think he is going to be happy about the price of new pumps. There is a break in part number for the injection pump so be careful with that

OOPS!
That's a costly mistake.
That pump is not a DYI rebuild.
If it was leaking fuel into the crankcase (which by the way is very very rare on these injection pumps) it need to be sent to a qualified rebuilder.
He needs to pack all parts up and send it off to a rebuilder.
It's a lot more common for the lift pumps to leak fuel into the engine.

I can rebuild them, but if it truly had a fuel leak it's not as simple as just putting it back together.
