Yes.. Nobody here will attempt to rebuild one. The clearances are less than 1/2 thousands and a flow meter bench is needed for recalibration. [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Problem is, this is such a specialized device, that it truely requires specialized training and tools. For example, if your advance piston has the slightest slop in fit, it won't work. Rebuilders shine a light through the bore with the piston in it, and study it for many minutes trying to determine if the slightest bit of light is getting through. If it is, then the bore must be rebored and an oversized piston installed. This requires a lot of machining experience and precision equipment. I have a big Index brand 32" verical mill in my basement, and I know I would not be able to do this operation with the precision that is needed.
Believe us when we say, this is a job left to Superman or a professional in injector pumps.
You'll save alot of money and time just taking it to a good injection shop to have it rebuilt.
Seattle Injector here will rebuild a pump for the 6.9 for 500 bucks and turn it up a notch for you if you want.
