Recently did a metering valve removal on a CP4 pump. Now that’s a scary job. Mechanical injection diesels are pretty good on handling small amounts of contamination. CP4 pumps on the other hand will eat them selves and trash the whole fuel system. $7000-$10,000 worth of parts at times.
Man thanks a lot for this video. It has been really helpful as I have this exact job to do next week on my Kubota D950 as diesel is leaking out the top of the injection pump. One question - seeing as I am going to be replacing the O rings on the 3 delivery valves, while I am in there do you think I should also replace the copper seals on the 3 delivery valves as well? Thank you.

I’ve heard you got to be carefully or it will change injector timing ?
Re sealing the injectors should not effect the injection pump volume or timing.
