[Vwdiesel] Rebuilding injection pump

[S Boser]

Hi All

Seems around here our injection pumps are starting to leak. A friends 1980 Rabbit was leaking for a while and he didn't notice it, his wife was driving it and the fuel had saturated the belt and of course the belt let go. She's trying to talk him into a new TDI
A couple days later I noticed a shiny spot from under my car after a typical Oregon rain, on closer inspection, it appears my injection pump front seal is leaking too.
I've bought a rebuild kit for my pump but of course there is no directions, can anyone point me to an available reference to rebuild this sucker? 
I have a bosch book on VE pumps but its more of a text book than an actual repair manual. 
I also have a couple of spare pumps so I plan on disassembling one of them first. And I am working on a test bench where I can operate the pump with an electric motor and measure the outputs on the bench.

Thanks in advance

Steve
