1945 TD9 Bosch Injection Pump rebuild in IH Construction Equipment Posted September 24, 2021 Thanks. It was "fun." It sure was a lot cheaper and easier than trying to switch over to an IH pump and injectors. It also gave me some more experience on my lathe making the fittings and such so now I'll know how if I need to tackle something like this in the future. By the way, I now have a pop tester that I hope I will never have to use again if someone else needs one. I'd sell it or loan it if someone has a need.
