The injector pump on our Oka developed an annoying minor leak from the rear distributor head several years ago but recently it suddenly got a lot worse so I took the pump off to fix it.
It was not a quick or easy job and I've written up some notes on our blog here in case anyone needs to do something similar, or you can download a pdf of the same information from the Contributions category of the Documents and Data section here.

Peter, yes the lower flange bolt is a bugga and I didn't anticipate having to remove the hydraulic pump and oil filter/cooler to gain access to it.
Maybe there's a better way but I couldn't find one.
