what's involved in removing an injection pump on a yanmar 2gm?

Hi all.
Just looking for a little help on removing my injection pump.

[sawingknots]

not much at all,remove the fuel lines [to the injectors and from the transfer pump],remove throttle linkage and the 2 retaining bolts,note the timing shims!

why are you removing it?replacing,rebuilding?if you put on a different pump it will need to be retimed using shims

I'm sending it out for rebuild. Sent the injectors in, they had lots of corrosion. Looks like I having governor problems with the injection pump.
This is a yanmar 2gm. Aside from the 4 nuts up top and the fuel lines I can't see anything else to remove but don't want to break anything.
My backround is with vw diesels. I don't have much background with these yanmars and up until recently haven't had to do much to mine other than service...

the lines are easiest to remove by using a wrench to hold and another to turn,if you arrange them fairly close together then use one hand to squeeze,i would strongly advise you to get a mechanic's manual for that engine,its been a long time since i worked on a 2gm but i'm fairly sure about the shims,it may require retiming

Sawingknots is correct on the use of timing shims for the reinstallation of the injection pump. A manual is a must read for this project.
